1. Introduction and What you're going to learn: Hi there, It's Thomas George, and welcome to this
audio production class. In this class are
showing you how you can record and process better audio. This class is for video makers, audio engineers,
YouTube as podcasters, voice-over artists,
online course creators, or for anyone who wants
high-quality audio. In this class, I've got
loads of stuff to show you. I'll start off by teaching you all about audio recording gear. So things like microphones, audio interfaces and
microphone accessories will then look at
treating your room or professional and DIY methods so you can record high-quality
audio at home. We'll then look at
how to use Audacity, which is free open-source audio recording and
editing software for Mac and Windows, show the essentials of how you can use the software
for recording, editing, and processing audio. This includes
teaching you how to record or capture your
audio in Audacity, as well as how to play back
then export your audio. After this, I'll show you some essential editing
techniques in their software, as well as how to
process your audio. This includes how to
remove background noise, as well as how to use
EQ and compression. Okay, So make sure you join me in this class if
you want to learn the essentials of how to
record high-quality audio.
2. My Recommended Budget Audio Recording Setup: Hi and welcome to this lecture while I'm going to show you what equipment you can use to get high quality audio on the budget. So you'll notice here. I've got a few different pieces of equipment. I've got this microphone, which is a sure sm 58. I also just applied this foam cover. The shore, sm 58 does have a built in pop shield for live performance, but at home it is best, really to try and get the best quality audio at source. Having a pop shield is a better option. But a phone cover like this can still do a great job against some of those plus of sounds, which is a blast of air you can get from certain words. These phone covers as well only cost a few dollars. Okay, moving on. We also have this box here. This is an audio interface. This allows you to record the microphone into the computer. The one I recommend here is the focus right to I to this has two inputs on this. Really great. If you're starting out, is quite inexpensive around about $100 and allows you to record your audio into your computer, and also you can hook up your monitors or your speakers via this audio interface as well. There's also a solar version, which has one microphone pre amp so you can just plug in one microphone, which is even more inexpensive if you want to say even more money. If you do want to record more than one microphone, though, do you recommend getting there to input version, which is called the Focus right? Scarlett to I t. Another thing you'll notice is this Microphone death stand. These are great if you want to do podcasts or voiceover work at home, these are around about $20. The next thing we've got here is an XLR cable. To connect this microphone into the audio interface on XLR cable will cost you around about $10 and the next thing you'll need is a pair of speakers to monitor your audio or a pair of headphones or effects. Also, if you want to save even more money, you can probably get all of their second hand for under $150 1 more thing to mention is, if you do want to recall this audio, you will need a computer or a laptop with some audio recording software, so this microphone actually is an analog signal. We need to convert it to a digital signal with this audio interface, and then we need to record it in a laptop or computer to just be aware that you will need to record this with Eva, a laptop or a computer. If you don't have a computer or laptop that you can use, there are two alternatives. One is You can get an audio interface that records onto your phone or tablet or two is. You can use a handy recorder such as this one here, which is the zoom hate five that actually records onto an SD card so you don't need a laptop or computer. You can plug the microphone directly in one of these inputs on record onto an SD card will go over handy recorders in more detail later on, so you may not think this equipment is the most inexpensive. However, it will give you the best quality audio at source for this price points. I do recommend having a look at this microphone, this shore sm 58 or a similar dynamic microphone and also this audio interface. The focus, writes Scarlett. Try to or if you just want to record one, input the solo when mixing your audio A. Recommend using a pair of speakers or high quality headphones. However, when recording, I do recommend checking good audio to make sure it's not distorting or that there's too much background sound. So for this, a cheap pair of earphones can get started for recording. But I don't recommend this for mixing. So just to show you what you can achieve with this equipment, I have been recording this entire lecture with this microphone and audio interface. I'm sure you can hear that sounds pretty decent. There are other alternatives to the set up, including a USB microphone, which is at a similar price on doesn't actually require in order interface. However, I do feel having a separate microphone and audio interface gives you more options. For example, you can use this microphone in over situation such as location recording or even on stage. Having a separate audio interface also means you can upgrade your microphone or even use a different microphone, such as a shotgun microphone, which be looking at later on so thank you for watching this lecture. Hope you found some useful information. The next few lectures were going to go into even more detail about microphones on audio interfaces.
3. Microphones for Video and Filmmakers: Hello and welcome to this lecture where we're going to be looking at different types of microphone. You can use four film. So when recording films, sometimes you might not want to have the microphone in shots. However, the audio is still very important. So in this lecture I'm going to go through four different types of microphone that you could potentially use when recording audio for film. So the first microphone I'm not actually counted. It's the built in microphone on the camera, so this is the audio from the built in mic on camera. As you can hear, it doesn't really sound that good. This could be OK if you're filming a vlog, wake up close the camera or in situations by all here isn't that important, However, if it's the film, if you want to do something professional, definitely don't recommend using built in mic on your camera. Next type of microphone is a dynamic microphone, so this type of mike is great for any voice, servers or podcasts. For this example, I'm using the shore sm 57. However, if you want to film video, have Mike out of shocked. This may not always sound the best. This is an example of the audio from the shore sm 57 right now. And it's not the best for situations like this because it's just too far away. However, for voiceovers, this is an excellent mike for beginners. Moving along. We have a shotgun microphone. This is the type of microphone you want to use for film because you can have it out of shot because of hyper directional, so you can point out your subject from a distance. Obviously, the closer you are, the better it will sound. But it's still much better than using. A dynamic microphone had much better than using the built in mic on your camera. So this microphone amusing right now, is actually the road video Mike, and it sits on top of your camera. Sophie using a DSLR or a mere less camera where camera that allows you to plug in a microphone. This could be a great option so you can plug it in, and it will actually record the audio onto your SD card so you can plug it in and it will add the audio onto your SD card so you don't need to sink the video and the audio. In post, however, it does sit on top of your camera, and if you have any shots where you really are from a distance, it's still not going to sound that good because you want the Micah's close as possible, even with a shotgun microphone. But for vlogs or situations where you're up close to the camera, this could be a great choice for recording audio. With Phil on, the audio you can hear right now is actually being recorded on this microphone to run about four feet away. Still sounds OK. Could be best if the mikes up close. So if I was a lot closer to the camera on the microphone, it would sound a lot better. What we really want is a shotgun microphone up close, which is where a boom standard comes in handy right now. The audio you can hear is recorded for a shotgun microphone on a boom stance, so you can't see in shock right now. But if you swap to the other camera, you can see this microphone. So this is great for situations where you don't want the microphone, your shop, but you want them. Mike as close as possible. So if you're going to be moving around, you will need someone to operate. This boom stands. You can get Mike stands and have a shotgun mic on a mic stand if you're going to be stood in the same place. But if it's a conversation between two people or someone's going to be moving around, you'll need someone to operate boom sand. So using a microphone like the one you can hear right now is a great shotgun microphone for recording audio for film. You don't have to use this microphone. I do recommend they're having a shotgun mike and having as close as the actor as possible to get the highest quality audio. If you don't want the microphone in shop on recording audio for film on the next type of microphone is a lavallee, a microphone. It's actually recording onto my phone. You can get Love Mike's that plug into power packs, and you can plug them into your camera or into an audio interface or portable recorder. But for this it just lets you record onto your phone, which could be super useful If you're recording for film, I do recommend using a love Mike as well as a shotgun microphone as a backup on it can be useful for certain applications. This could be useful for really wide shots or when the actor is really far away from the camera on the boom. Operator can't get into the right position without being in shocked. So let's just do a quick test off the different microphones now. So this is an example off what the audio sounds like. This is an example of what the audio sounds like. This is an example of what the audio sounds like. This is an example of what the audio sounds like. So I hope you realize, now that using a shotgun microphone does make a big difference. You want the Michael's closest possible on out of shot, really when recording audio for film. And I do also recommend using a love Mike as a backup mike. And definitely don't use the built in mic on your camera unless you really need Teoh. And it's in situations where the audio isn't too important. But if you want to take this seriously, just remember, audio is very important. So thanks for watching this lecture. I hope you found useful. I'll see you in the next one
4. Different Microphones and their uses: Hello and welcome to this lecture where we're going to be looking at microphones. So if you want to record any kind of audio, getting an external microphone is very important. Of course, On a lot of cameras and laptops, you will have a built in mic, but it's never as good as having an external microphone. So here, right from 2 May I have a selection off different microphones. I'm going to quickly go through them now so you can hear what they're each individually sound like. So the 1st 1 here is the electro voice. Ari 20 Mike Number two is the shore, sm 57. The 3rd 1 is the zoom hate five. They're moving along. We have the shore sm 58. And then we have this microphone here, The blue Yeti. They're not here. I've got a rode NT G one. This is a shotgun microphone and then down about two lapel mikes. This is the first lapel mike, which is the road link and then below this I have the road. Smart laugh. Plus on. Now let's go into a lot more detail, starting with this first Mike, the Ari 20. Okay, so this first microphone is the electro voice, Ari 20. It's this microphone here, as you can probably hear it sounds great. The sound you can hear right now is the sound recorded into this electro voice, ari 20 of no processing apart from gain, because all of these mikes will be at the same volume level, because sometimes if you hear audio louder, your mind will play tricks on you and you think it's better. So it's a great clear microphone you may have seen it before is very popular for podcasts, for radio shows for voiceover work. Very classic microphone hasn't changed in such a long time. There are different models similar to this, but this is the one that I like. The electro voice Ari, 20 as you can see as well, is quite a large microphone, and it is quite heavy, so it may not be ideal for location recording, but it does sound great if you hear this microphone compared to the built in microphone on my laptop right now. So so much different on the built in mic on the camera. It's so much better than any built in microphone, but it is quite expensive, Mike It's a great one. If you want to consider doing a podcast work and the voiceovers or any radio shows, the next microphone is this one here. This is the Shure SM 57. This is another classic microphone. It's instrument Micah's. Well, you go to any big recording studio. There will always have plenty of these microphones. It's we kind of go to jack of all trades entrant microphones great for snag drums. Great for guitars. Also fantastic for live performance, you'll notice, though it doesn't have a built in pop shield. So we'll have to have a pop shield or pop filter. We may get some close ifs. It is very durable, though on it can withstand a lot of life performance. So someone knocks over laxed and it probably won't break. I don't ever recommend dropping the microphone, but these two microphones, especially the 57 58 we look at later very durable, so going back to the 57 you can hear now has a great tone. It's also being used for voiceover work. It's also even being used for presidential speaking, so it's a very good jack of all trades microphone, but especially great for instruments for a microphone is also quite inexpensive. It's around about $100 new. Or you could buy it second hand for a lot less as well, although it may not be the number one mike for voice overs, if you can find a great deal, it's a great my toe have as a backup, or it's a travel microphone as well. So if you're just starting out with microphones and you want to save some money and not spend too much on the mic, I do recommend having look at this all the one jack of all trades instrument microphone, the shore sm 57. Also, be sure to check out the PdF attached this lecture. Want more information about these microphones? Okay, going along. We have the zoom hate five in the middle here. This is actually a handy recorder, so it's more than just a microphone. We have this microphone on top this X Y pattern. This stereo Mike actually allows you to attach different types of microphones that up on the Boston we have two inputs, so you can actually recall two different microphones into this at the same time and record this one on the top. So this is great for filmmakers. Location recorders you want to be out about, But you don't want to actually take a laptop with you. This you can all record just on this one. Device on what you can hear right now is actually been recorded onto an SD card. There are various different handy recorders out there. Zoom on the main ones that actually create them. There's a zoom H one which is similar to this without the inputs. This is a zoom hate five. There's also the zoom hate six, which is very popular, which has four different mic inputs. So if you recording our location, you don't take a laptop with you on audio interface. I definitely recommend having a look at the Zoom Hedge. Five on moving along. We have the shore sm 58 similar to the short s and 57. However, this one has a metal pop shield, which is why it's very popular for life performance. So you don't read a pop shield like these over the top has one built in, so it's very durable, which is why it's also used for live performance. If you see your favorite rock band, a swing in the microphone around the cable. It probably be OK if it's the shore sm 58. It's also quite inexpensive, around about $100 on a great microphone for life performance similar to the 57 but mainly for vocal live performance. So if you want to sing or you don't do a conference, I recommend having a look at the shore sm 58. So for the short sm 58 actually all of these microphones here that I'm going to talk to you about there are over alternatives. Thes are really just the classic Go to Mike's. If you want to check out of a company's, please feel free to do that. Also, be sure to check out the PdF attached this lecture for more information about these microphones. If you can't quite remember everything that I'm saying, okay, going along, we have this USB microphone, which is the Blue Yeti microphone. It's a USB microphone because we don't need on audio interface on analog to digital converter. It's got one built in all. We need to do it. Just plug in the USB and we're good to go this microphone has different polar patterns, and it can be used in different situations. If you just wants to a voice over there like this, I do recommend using cardio, which would just pick up really the front off the microphone. If you are recording a band or room, you can use the Omni Polar Pattern on. It also has a figure of eight pro Lopata, which might be useful if you're recording to vocalists or two singers at the same time. In the PDF document attached to this lecture, I have included more information about polar patents. So this is a great, inexpensive microphone. If you just want to plug in and play and not have any audio interfaces you can use. This microphone is very popular for online course. Creators also live streamers. It doesn't quite sound as good as having a dedicated analog to digital converter or an audio interface. The XLR microphones, like these ones here will sound better, but it is good to start with. And if your brand new you don't to spend too much money on audio gear, I do recommend having a look at a USB microphone such as this one. The blue Yeti. Okay, and next is a shotgun, Mike. It's actually a condenser shotgun, Mike by road. This one is great for any video makers on. They don't want their mike in shot. So it's actually super cardio ID, which means it has a very directional pattern, so you can actually use it from a distance as long as you pointed in the right direction. So it's very popular to use a condenser shotgun, like in the movies, films TVs, but they don't want the microphone and shot. So this one's actually quite inexpensive for one of these types of Mike's So Ryan, about 100 to $200. But in the big movies, big TV sets there will spend a lot of money on these kind of microphones. So this one actually requires phantom power or additional 48 volts. He can turn on phantom power or the plus 48 V button. Normally on your audio interface or sometimes inside your computer, just make sure the gains all the way down before you turn on Phantom Power on gradually increase it. So this is a great mike. If you want to actually record audio for video and you don't want to have the mike in shot . Okay? The next microphone is a lavallee, a microphone. The notice Here I've got these two Clipper Mike's the top one here is the road filmmaking kit or road link on. This is great if you want to record audio video, so you'll see these clip on likes on a lot of new shows. A lot of interviews. So if you can't actually get a shotgun, Mike there or you want to have a mic closer to you can use one of these love Mike's. So this first microphone is the Road Link filmmaker kits that has two of these power packs . One of them attach is to the microphone, and the other one can attach to your camera or to your audio interface. So these are great if you're out and about and you want to record audio with video. These are quite expensive around about $300 on the next level. Air Mike is a lot more inexpensive I'm going to tell you about now, so there's microphone below. You might be able to hear the difference. This is the road smart love plus, and this actually attacked us to your phone so you can record audio into your phone, fusing iPhone. You might have to have a double, but it works absolutely fine. So if you're out on, all you have is your phone review that have a camera or on audio interface or a zoom H five . A handy recorder, for example. You could just grab this microphone on your phone and start recording high quality audio and even use the camera on your phone if you want to create a flog. So these are useful for YouTubers vloggers who don't want to take much gear with them you need. It's a small microphone on your camera. Okay, so I've gone through a selection off my favorite microphones here, and they all have different uses. It really depends what you want to record audio for. If you recording audio for podcasts or voice overs, you may want to consider this ari 20. If you want to record instruments or for live performance, maybe have a look at the shore s and 57. If you want to record vocals live or for conferences, maybe have a look at the shore sm 58 for a USB microphone This is a great one, This blue yeti. It's a lot more inexpensive than actually buying audio interface. However, it may not sound as good. Zoom hate. Five. This handy recorder is very useful for video makers who don't want to take laptops or order you interfaces with them. We need to take is this small little recorder. If you're recording for video and you do want to capture high quality audio, do you recommend having a look at shotgun microphones? This can be more expensive, but they do get a much better sound than generally one of these love Mike's, which is still great, though. So if you do want to clip on Mike, if you're doing an interview, that kind of thing I do recommend having their look at love Mike, the wireless power pat ones. This film making kit will generally sound better. The ones that go into your phone, however, is still very useful, and I actually carry this little smart left plus in my pocket at all times. So in case having an idea or a video American film it wherever I am, okay, just for another quick comparison. Let's go through what these microphones sound like So the 1st 1 here is this electro voice , Ari 20. The next one is the shore sm 57 going along. We have zoom hate five. Then we have the shore sm 58. Then we have the blue Yeti USB microphone up here we have the road nt do one shotgun microphone. Then we have these two lapel mics. The 1st 1 is the road link. This is the filmmaker Kit on the one blow is the road smart laugh plus then just for comparison, we have the built in mic on our laptop and then we have built in mic on that camera. So hopefully now you should realize not to use the built in mic on your laptop or camera and to definitely get an external microphone. So I hope you've enjoyed my selection of different microphones. We understand a little bit more about what they sound like and how they can be useful. So thank you for watching this lecture. I hope you found it useful. And I'll see you in the next lesson.
5. Microphone Accessories: Hello and welcome to this lecture. We're going to be looking at some recommended microphone accessories, so if you have a microphone and audio interface, you might want to consider getting some accessories for your microphone to help you improve the quality off your audio. This fierce accessory here it's kind of all in one package is a mic stand, a shock mount on the pop shield so this Stan could be useful when recording audio on your desk. So for a podcast or even a voiceover on the shot, Married helps reduce some vibrations. For example, bumps on the desk all movement of your feet on. Then we have a pop shield, so this is very useful for reducing some of the close of sounds. So these are blasts of air that come from saying certain words. One thing to know is this does not come of a microphone, however, is great for lightweight microphones such as the shore s and 57 or the short s and 58. But if you want to use a bigger, heavier microphone like this one here, the electro voice Ari 20. I don't recommend this mic stand this microphone stand package however, is great fuel beginner as it really is all the one device accessory. If you want to record podcasts or tutorials on next, is this one speaking into right now, which is the more deluxe and far superior version of what I just showed you? This is a lot sturdier allows you to move. The microphone, however, is a lot more expensive, but it doesn't allow you to hold much heavier microphones. I do you recommend this for podcasts, voiceovers, or if you want to record audio on your desk, these are excellent, but do cost a lot more than the first package that I showed you. So it only really recommend this. If you want to take recording audio seriously, if you're beginning, the first package is great for a lightweight microphone. If you're just starting out, though, I do recommend spending the extra money on the better quality microphone than just a boom stand like this. Okay, and moving along. We have this death stand here. This has a solid metal base and allows you to actually have much heavier microphones on this stand. This death stand is quite heavy, though I don't recommend it for traveling but it doesn't allow you to hold much heavier. Mike's such as this one, the electro voice Ari 20 and can be useful for podcasts or any work in the studio where you want your microphone on the desk moving along. Here we have this large reflection filter. This is great if you have a room that has a lot of reflections, and you want to make the room sound a lot better without actually treating the room. You can use a reflection filter like this, so this will reduce some of the reflections in the room. These can be quite expensive, but they can be great if you're using a certain type of microphone, such as a condenser microphone, which is more sensitive, then a microphone like this, which is a dynamic microphone but only really recommend having a look at a reflection filter. If you do have a room that doesn't sound the best and has a lot of reflections, I'd always recommend trying to find the best place to record audio. However, if it's not quite possible and you're still getting a lot of reflections, a reflection filter like this could be a great addition to your recording audio set up moving along. We have a pop shield here, so this could be very useful for reducing some off the close of sounds to These are the blasts of air that you may get from speaking into the microphone. Certain microphones, such as the Short s and 58 also the electro voice Ari 20 do have a built in pop shield, but it can be great to double up to actually reduce some of those Pelosis sounds. If you're using a condenser microphone rather than a dynamic microphone like these, I do recommend getting a pop shield as condenser microphones can be a lot more sensitive to blast of air. There are other types of pop shields as well, such as this, which are made from a tight light material. So these basically do the same thing, but they're less durable. They are, however, less expensive than the metal pop shields. If you're on a budget, though, or maybe even if you're traveling and you want to be lightweight, I do recommend getting one of these foam microphone covers, which can help reduce some of those place of sounds as well. It won't sound quite as good as a pop shield but could be better than not having a pop shield at all. So if you recording outside and using a shotgun microphone, do you recommend using a wind muffler so these could be very useful for reducing any wind sound? There are of a microphone accessories available thes of the main ones that I use. If you're just starting out, I do recommend getting this first accessory packs that talked about the stands for shock mounts on the pop shield. But this will only really work with a more lightweight microphone, however, is great for podcast or tutorials or voice overs, and it is quite inexpensive. So thank you for watching this lecture. Hope you found it useful. We understand now just some of the accessories you can use for microphones from recording audio.
6. Boom Operating Tips: Hello. Welcome to this lecture. I'm going to show you a few tips operating a boom stand, so tip number one is toe. Have the microphone as close as possible to the subject, ideally about two feet away, if possible. You also want to make sure that the microphone is pointing at the subject's mouth, not just in the direction you want to point out their mouth because this is hyper directional, and it will sound a lot better pointing at the subject's life, then just kind of in their direction. You also want to make sure that the distance is always the same. So if the subject is moving, make sure you keep the same distance between the microphone on the subject. This is important because it may affect the sound quality if the distance changes throughout the shot. Next is the know the script. So if there's a part of the script where the subject stands up or if they're moving or if there's two or more people, you may have to change the position of the microphones. We really need to know the script. Some top boom operators actually know the script as well as some of the actors. This is very important because you need to make sure that the microphone is in position before the actors start talking. It's also very important to remember that small movements can cause vibrations that will be picked up by the microphone. So using a big understand that allows you to put the cable inside can really help with this . Otherwise, cable will be on the outside and might actually bash against the stand to cause additional unwanted noise, moving your hand on a boon Stanick and cause additional unwanted sound. Do you really want to keep movements as minimal as possible? There is a technique, though, to actually move the mic without causing too much sound. So if you hold the boom stand between your thumb and index finger on twist with your other hand, you can rock the mic. This will cause minimal sound of allies. You're moving your hands around calls a lot of noise, which may ruin the shots. My next tip is about being aware off lighting. So if you controlling the boom, just be careful where you actually have it. You want it close a subject as possible. However, you don't want it causing any shadows. If you cause a shadow onto one of the actors faces, for example, you completely ruin the shot. So work where the camera operator and find the best place to have the boom mic without causing any shadows. Also, you may want to be more careful of the lights when you're in the studio rather than natural lighting outside on. The next tip is trying not to be too distracting to try not to make any sudden movements or noises that may distract the actors and also try not to be in their eye line or making the eye contact as it may distract them whilst they're speaking. Also, be aware of what kind of shoes you're wearing. Make sure they're not noise issues, or he may add some additional noise to the shots. There is something you can use called Hush heels, which is patting material which sticks to the bottom of your shoes to kind of mitigate any foot movements. One more thing to mention is I'd look at getting a shock amount as well, like this one here, as this will reduce vibrations on any unwanted noise. On the next tip is to learn some camera lingo. Maybe learn about lenders because you will be working with the camera operator. And you really want to know the language about filmmaking. We might embarrass yourself and not know where to actually go or what to do. For example, no in different types of lenses and how wide they are that you know how close you can get to the subject without being in shot. So these are some of my top tips for operating a boom stand. I found this lecture useful, and I'll see you in the next one.
7. Microphone Accessories to Reduce Wind Noise: Hello. Welcome to this video. I just want to show you some outside audio recording tips. So out now in the big park is a little bit windy, and you might be able to hear on the shotgun microphone. Now some of the wind sound. This could be very distracting when you're recording a video, really don't want the wind sound, especially if you outside there's a few different things you can do. So we can get is some wind noise reduction foam in sickness onto a shotgun? Mike, we should get rid of some of the wind sound. So let's add this now. We might be able to hear that it's reduced some of the wind side. If you're having a lot of wind sound, you can get a wind Mufleh, so it's a lot bigger. It's also called a dead cat. Not really sure why, however, Let's to touch this now, and you might be able to hear the difference, and hopefully it will reduce some of the wind sacked. If it's really, really windy, though it might not reduce. Also, just be careful and find a good location. Maybe that's surrounded by trees or isn't in a really windy location. Okay, now I've added the window flower you might be able to hear. That's reduced some of this wind sound. Remember, this is a shotgun, Mike. If you do want this out of shots, you can keep it further away. But just be careful with wind. Sound way you are Maybe not record audio on top of a hill or some of super windy, maybe by the beach. It's not going to get rid of all of the wind side, but will reduce it. Also notice here I've got a lapel microphone and level there, Mike, and this has a small wind muffler as well, so you can get these wind mufflers for this small clip on love. Mike's as well. I just want to make this quick video just to give you a comparison off the wind. Sound with and without any kind of wind reducing foam or even a win Mufleh. Another quick thing is, if you recording outside, try and point your microphone in the same direction that the wind is traveling so reduced that breeze sound
8. Audio Interfaces and Examples: I welcome to this lecture where we're going to be looking at audio interfaces. So in front of me now I have four different audio interfaces that each have their own advantages and that each at different price points. So in audio interface has a few different functions. And I'm going to quickly run through them, though. So this microphone here, this is plugged in Irvine XLR Cable on this will send an analog signal. So we plugged this XLR cable into our audio interface on Then we can increase the gain with the microphone pre ampere. Then after this, we're going to send the signal. So this analog signal into our computer so the audio interface actually convert cyst analog signal to a digital signal so we can record the audio with that computer. So this actually works that of a way to as a digital to analog converter so you can send us recorded audio to a set of speakers because the audio interface does convert digital to analog as well. It also can be high quality than the digital to analog converters on your computer. With an audio interface, you can also control the amount of volume being sent up to your speakers with unmonitored I'll also most audio interfaces will have a dedicated headphone output as well. So this first audio interface, this is the focus, right? Scarlett to I to I recommend this audio interface for anyone starting out. It's quite inexpensive around about $120 there are various different versions. This is a to I to so it gives you two inputs. There's also the solo, which is one inputs, and you can even get four on the eight input version. So the audio you're hearing right now is actually being recorded on this focus, right, Scarlett to I to So the microphone preempt might not be quite as good as the more expensive audio interfaces that we're going to look at later on, however, is still great. And if you're starting out, this is a great audio interface. To consider on the next audio interface is the Shore X to you. This is great because it's so small. The audio you can hear right now is being recorded into this audio interface, so it does have a lot of the same functionalities as the over audio interfaces. It allows you to control the game level On output level, however, is only one input, and you can only record on XLR cable of this. So if you want to record, say, a guitar or maybe a keyboard, it may not be able to do this with this short X to you. However, if you just recording a voice over or maybe a podcast, this could be great. One thing to mention as well is it doesn't have a dedicated speaker output, however, it does have a headphone out. It also has phantom power plus 48 volts, as do all of these over audio interfaces. So for certain microphones, you may need an additional 48 volts to power the microphone. This microphone, however, is a dynamic microphone and does not require phantom power. However, it's there just in case you're using a microphone that does require phantom power. So this is a great lightweight, inexpensive audio interface around about $100. The pre amp. May not be quite as good as these other audio interfaces, however. It's a great one to consider if you want to record audio whilst you're traveling, okay, and the next audio interface is this one here. This is the Apogee duet. So the audio you can hear right now is recorded through this order interface. So this is quite small. Obviously not a small lightweight as a shore X to you. They compared to this audio interface here it is very lightweight. So the main thing I like about this order interfaces how clear the mic pre amp sir, And you can actually add a lot of gain, which could be very useful for certain microphones that require more again, such as the electro voice Ari 20 to keep this audio interface slim line. The audio inputs aren't actually on this interface itself. On these breakout cables thes are combi XLR jack inputs. So you concert even XLR cable or a jack thes breakout cables also have monitor outs so you can plug this audio interface into your speakers. There's also a headphone out at the bottom off this order interface if you want to monitor with headphones whilst recording audio. So this apogee duet is a great audio interface. If you want to have some clean pre amps that can give you a lot of additional gain and also have an audio interface that isn't too big and bulky. It is quite expensive, though it can be up to $600 but it will give you a better sound than, say, the focus right to I two or the Shore X to you on the next audio interface is this focus, right claret for pre. You can get this with two pre amps. Four preempts on. There's also an eight preempt version. So out of these four audio interfaces, the focus right. Clara is the only one that requires mains power, so for the studio is great. But if you want to record when you're traveling on location, I don't really recommend it. The microphone I'm speaking into right now it's being recorded through this focus, right clarets, and as you can hear it sounds great. This audio interface has very clean and clear microphone pre amps. This focus right claret is a bit more expensive than, say, the scarlet. It is around $550. However, it has got really high quality microphone pre amps. So if you don't want to spend a bit more for a really great quality audio interface for the studio, I recommend having a look at the focus, right? Correct. One more thing to mention is the claret does have additional line level inputs at the back , which can be useful if you have any additional pre amps. Let's now have a quick comparison off these four different audio interfaces recorded with the same microphone using the same processing. The microphone I'm speaking into at the moment is the shore sm 58. The microphone I'm speaking into at the moment is a Shure sm 58. The microphone I'm speaking into at the moment is the shore sm 58. The microphone on speaking into at the moment is the shore sm 58. You may have noticed there that the more expensive audio interfaces give you a higher quality sound. However, the cheap audio interfaces a more than adequate for most applications. So each of these four audio interfaces do offer different features, and they do have different quality pre amps. There are different price points as well, so it really depends on how much want to spend. But if you're starting Garrett, I do recommend having a look at the focus right to I, too. If you want to spend a bit more money for the studio. A recommend having looked at the clarinet. And if you want to be more portable, I recommend having a look at the apogee Gerets. But if you want to save a bit more money and you still want to be portable than I recommend , having good look at the shore X to you. So thank you for watching this lecture. Maybe understand a bit more now about audio interfaces on. I'll see you in the next lesson.
9. Headphones and Monitors: Hi and welcome to this lecture. We're going to be looking at headphones on monitoring. So for headphones, you get two different types closed on open back headphones so the majority of headphones will be closed back. So this is where there's no sound coming out of the back of the head phones. Open headphones is where the sound also comes out. The back of the head phones. These can be useful for some mixing situations, but if you want to record audio that I definitely recommend getting closed back. Headphones, studio monitors and studio headphones are ideal as they don't have any built in e que, which adds color to the sound. However, if you have a pair of headphones or speakers that you're completely used to, then you can always mix on these as you know what they sound like. Let's now talk about reference tracks. I do recommend finding an audio example that you want your recording to sound like So. For example, if you're mixing a podcast, find another podcast that you want yours to sound like so regularly. Listen to it while you're mixing yours, so you know that your mix is always going to be in the right direction. It doesn't have to sound exactly the same, but using reference tracks is great for training your ears. I also recommend checking your audio on different systems, So whilst you're working on your audio and you've got it to a standard that you're happy with, it's worth checking this on different speakers, so make sure you check your audio on three different types. One mini set of speakers. For example, a blue tive speaker for your phone, one standard set of hi fi speakers and also your built in computer or phone speakers. Different speakers sound different. So if you're mixed sounds good on all of these different varying types, then it will probably same great everywhere. Okay, so that's just a quick overview of headphones and speakers. Hope you found this letter useful, and I'll see you in the next one
10. Room Treatment Tips: hi. In this lecture, we're going to look at some room treatment tips. So first of all, when the sound is created, for example, your voice, the audio will project out in all directions. The direct sound will travel in a straight line into the microphone, and the rest is reflected sound, which means it bounces between the surfaces off the room. A short time later, though, this will bounce back into the microphone, so the time it takes for the sound to bounce back and hit the microphone really depends on the size of the room. The number of times it bounced back into the microphone also depends on the shape of the room and how the room has been treated. Unless the room has been designed tohave pleasant acoustics than the reflective sound in the room will likely add unwanted room sound. Different materials can also change the frequency. Balance off the reflective sound, however, unless you're in a room that's being designed to sound good than it probably won't. For example, recording studios have some natural room reverb, but they have been designed carefully to sound that way. Another example is a cathedral they've bean designed like this to create a certain sound for the choir, as it can be very expensive to design a room in a certain way. An alternative is to treat the room in the way that reduces the amount of reflections. Now let's have a look at some top tips to treat your room of her any specialist equipment. It is important to realize that there's a difference between soundproofing on acoustic treatment. There are two things, though you can do to help improve the sound off your room. Number one is removed, the natural reverb off the room, and number two is to diffuse the sound of the reflections. The worst thing is to be sat in a small square room, which has hard surfaces all around it, such as walls windows, because the sound will just bounce back and forth between each off the surfaces. This will create a sound, which is a flutter echo, and it's not what you want. The rosters and things you can do to reduce this room selection is important. So try and choose a room that's an odd shape if possible. This way, the sound will bounce in different directions around the room and doesn't go back and forth directly between the four walls. Some rooms, however, just sound more pleasant and others just completely by chance. But try different rooms in your house or recording location and see which sounds best. First of all, remember, different positions off the room will have an effect on the sound I recommend against the common idea that covered with egg boxes is any good, because due to the walls being so close, the reflections will be much stronger on egg. Boxes are so thin that almost all frequencies will simply pass through them. Your best option is a medium sized room. Ah, good way to test the room is to just clap your hands in some bad sounding rooms. You will hear a heart wringing sound, which is flutter Echo on. This is common in small square rooms. Alternatively, in larger rooms, you're more likely to hear a pleasant reverb, which won't causes many issues when recording audio. So once you've chosen a room that sounds reasonable or you have no choice over the room, there are some things you can do to help. You can look at absorption so soft materials can help absorb some of the sound that bounces around the room. Also, you can close the curtains off your room or hang up a do they on one of the walls. You can also try leaning a mattress against the wall, and also try putting an extra rug down. You can also try having a sofa in the room, because this can help absorb this out a bean bag and generally anything soft can help. Also, thicker material can be great for absorbing those lower frequencies. Also, packaging foam on any insulation you confined could help absorb some of the sound that's bouncing around your room. The next thing you can do is diffuse the sound diffuses work by scattering the reflections off the sound so it doesnt reflect right back into the microphone so this can have a more natural, pleasing sound. There are different things you can use to scatter the reflections, which include furniture so cabinets, chairs tables. Also, bookshelves can be great if you also have a wardrobe full of clothes and shoes and toys, and open that up aswell. These things can help. The cheapest and easiest thing I recommend is actually hanging a do they are behind you and also putting up a mattress in front of the microphone against the wall. This could make a huge difference and improving the sound of your room. A combination of absorption on diffusion is really the best. Alternatively, you can buy acoustic treatment. So many companies sell foam acoustic treatment packages, which can make a huge difference when mixing and recording music based traps are probably the most important form of acoustic treatment. This will help treat the lower frequencies in the room. However, If you're working with audio just for a voice, you often cut out some of the lowest frequency. So these the ones that would have bean attenuated by the base traps. If you have the budget, I would definitely recommend getting based traps. But if not, I would spend your money on other acoustic treatments. Acoustic panels could be the most cost efficient way to treat your room. It won't give you an acoustically perfect room, but it will heavily reduced the amount of audible reflections in the room or elects make some great acoustic panels. But they can be quite expensive. I recommend having a look on eBay on when purchasing. Make sure you get the most dense ones you can find on. It's measured in kilograms per meter, cubed on around about 25 meters. Cubed is great. The other way, which is slightly more expensive, is using fiberglass insulation. Acoustic panels. Companies like Prime Acoustic make these. However. It costs a lot of money about $1000 for a full room treatment kits. You can, however, make some of these yourself by building within frames and purchasing the insulation material yourself. Realistically, if you're just starting out, you probably won't want to spend a lot of money on this. However, the sound of your room will make a huge difference. So do what you can with D i Y methods. But if you're still unhappy with the sound, a recommend looking into professional acoustic treatment. So there's just some tips about Reum sound hoping found this useful and I'll see you in the next lecture.
11. Room Treatment Example: Okay, so this is a standard kind of room that you may have to use for recording audio or mixing audio is far from perfect. It's a square shape, has a odd shape ceiling. Let's hear what this room sounds like. Now I'm just going to clap three times. You may have heard some flutter echoes there. It's not ideal. But what we're going to do now is apply some acoustic treatment. As you may imagine, not everybody can have their own specialist room just for recording audio podcasts. So for this, we're going to try and transform this room. Make it as good as possible for recording and mixing audio. Okay, Now, let's have a listen to a podcast microphone in this untreated room. Okay, So what you can hear right now is recorded through this dynamic microphone here on. This is very suitable for podcasts or voice overs. Now she can hear. It doesn't sound amazing in this room. On defy. Stand back, the quality you will get worse. So what we really need to do is be quite close to the microphone and also treat this room. Okay, Now, let's have a listen to this podcast microphone after we treated the room. Okay. Now, on speaking into a dynamic microphone, this electro voice, ari 20 on average distance you could use for voiceover or a podcast in this treated room on when I go back, you can tell the quality is not gonna be quite as good. But in the treat a room like this, it still sounds fine. Okay, And now we've treated this room. Some of this is professional acoustic treatment on some of this is D I Y. Now let's hear this room again. I'm going to clap again, and you should notice there would be less flutters than without this treatment. As you can hear, it's made a big difference. The room is no longer ringing out and just sounds a lot more suitable for recording and mixing. As you heard before. This room did sound quite bad, and now it's a lot more usable. So this is what you can do to your room with some simple acoustic treatment to treat this room. I use, um, d i Y methods, which included a large piece of foam. I also added some beanbags into the room on also put down a rug to help absorb the sound of the room as well. I use some professional acoustic panels which are hung on the wall also onto the ceiling. Okay, now, let's just do a quick comparison again between the untreated room on the treated room. So I hope you can hear that treating your room can make a big difference to the quality off your audio. So thank you for watching, and I'll see you in the next lesson.
12. My Recommended Audio Travel Gear: Hi and welcome to this lecture where we're going to be looking at portable travel recording equipment. So whether you want to film a podcast in Thailand or video course the other side of the world or maybe even you want to film travel vlogs having high quality audio still important . But when travelling, though really don't want to take too much. So I'm going to show you some of the recording equipment I take when traveling. So, first of all, I've got this here. This is a love mike, a level air mike by road, the road smart love plus and it literally plugs into your phone and you can record great quality audio off your phone. So let's have a demonstration there off. What? This audio actually sounds like this is a test off the microphone. Having high quality audio whilst on location can be very useful. And also here I've just got a portable power brick and just a plug for my phone so it doesn't run out of battery. And that's all you can literally take if you just want to be super lightweights. So you can actually film videos and it will record the audio onto your video for your phone . So if you on the budgets and you want still want great quality audio recommends Just getting a microphone that plugs into your phone. This one's around about $50. Okay, and now I've got packed number two. This all fits in this small bag. It is a bit more expensive, a little bit heavier than the previous level air Mike. However, it doesn't allow you a few more possibilities when recording audio. So festival here. I've got some closed back headphones. So when recording audio really want closed back headphones? These air Sennheiser hates due to five mark two. There are plenty of of a headphones available. These are just the ones I like when travelling. Okay, and then I've got a handy recorder. This is a zoom hate five. This has a built in mic on the top X Y microphone and allows you to plug in two different microphones here. The bottom and then the microphone are used with zoom hate. Five is the shore sm 58 because it's really durable. When traveling in May, drop your bags and yeah, this is built really well. You can hold it like So if you wish, a lot of people do hold, that s and 58. It's great for stage performance. Or you can use a little stand. Okay, so this is a travel stand with a shock amount on a pop shield, like said, within a short s and 58 you might not need a pop shield is good as well. Just in case you have any more PLO sieves, it will mitigate that as much as possible. So you can really put this on your desk and you can record voiceovers or podcasts just with the shore sm 58. That's the second option. And of course you'll need a cable which plugs into the bottom of the handy recorder. So let's have a demonstration there off. What? This audio actually sounds like this is a test off the microphone. Having high quality audio whilst on location can be very useful. Okay, And pack member free is a bit heavier and, to be honest, a lot more expensive. And this is what I'm currently using right now to record a lot of my podcasts and voice overs when I'm out of the main studio. So let me show you What's inside? So first of all, we have another power off closed back headphones. The's at the Sennheiser is hasty. Two fives on when we open this up. It's actually this microphone here that I take with me, but without the pop shield. So just the microphone. This is the electro voice, Ari. 20. Okay, and then I have a stand. This is a man photo stand. It's actually a camera tripod, but I've got this attachment here. Changes it from basically camera tripod into a microphone tripod. So this is useful if you just want a small lightweight tried. But then I've got a map but charger because I will be recording within that book. Then in here I've got my cables for my audio interface. On the audio interface I like to travel with is the apogee. Juliette. This has a really amazing signing pre amp. And you can still travel with this audio interface. It's not the smallest, however. It's still quite lightweights, and in here I've got the cables for this audio interface. I've got the XLR cable for the microphone and then I've got these breakout cables, so this allows you to actually input to different XLR microphones and that has some speak out cables here on then, in the back of this bag, I keep my map book. So let's have a demonstration there off. What? This audio actually sounds like this is a test off the microphone. Having high quality audio whilst on location can be very useful. Okay, so I've got free, different options here. It really depends on how much you want to spend, how much weight you have. Despair. And also how serious you want to take recording high quality audio. Option one is literally just really this love Mike. Option number two is the short s and 58. This dynamic a vocal microphone with a zoom hate five handy recorder on a pair of headphones and option than the free is this microphone you can hear right now. However, with this stands this audio interface, the apogee Juliet and it never pair of headphones. Let's hear what these free options sound like again. This is a test off the microphone. Having high quality audio whilst on location can be very useful. This is a test off the microphone. Having high quality audio whilst on location can be very useful. This is a test off the microphone. Having high quality audio whilst on location can be very useful. Okay, so you can probably hear there is a difference between the free options. However, they also much better than just using the built in mic on your camera or the built in mic on your phone. So these are my free options for recording audio when you out of the studio, it really depends on how much you want to spend. I'm really how much weight you have Despair because option than the free is quite heavy. Obviously does sound the best out the free, but it is heavy. Option number two it is a lot more lightweight. And this was my old travel recording set up an option number one actually have with me at all times. I make sure I've always got this microphone in my pocket. So if I want to record some audio, that microphones always with me. So I hope you found this lecture useful, and I'll see you in the next one
13. Audacity Introduction: Hi there and welcome
to this next section where I'm going to show the
essentials of recording, editing, and processing
spoken voice in Audacity. Audacity is free
open-source audio recording and editing software
for Mac and Windows. And the techniques
I'll show you in the next few sections could be useful if you create podcasts, tutorials, or videos online where you want to be
able to record audio. In the next few videos,
I'm going to show you how to record or
capture your audio, as well as how to play back
and export your audio. After this, I'll show
some essential edits and techniques and audacity, as well as how to
process your audio, including removing
background noise and how to use EQ
and compression. So by the end of the
next few sections, you should know the basics of using Audacity for recording, editing, and processing
spoken voice.
14. Audio Recording Setup in Audacity: Hi there and welcome to this
video where we're going to be looking at
setting up audacity. So you're ready to record audio. So when you open up Audacity
for the first time, it may look something like this. You can always click and
drag to resize or Udacity. I'm just going to click
and drag from the corner. The software fills up
the entire screen. You'll also notice that we have this blank space in
the middle here. And when we record our audio, this is where the audio
waves will be displayed. And we also have these
buttons at the top. The main ones we're going
to be looking at in the next few videos is this
transport section over here. And we'll also be looking at the input monitoring
section here as well. The first thing I
would do is actually change the sample
rate of the project. If we go down to
the bottom left, you can see the sample
rate is 44,100. And I would actually change
this to 48 thousand. So we can click on
the arrow here and change it to forty
eight thousand. Forty eight thousand is the
standard sample rate for audio when working
with video Music, 44,100 is often used. But if you want to
record audio for video, and I recommend using
forty eight thousand. Forty eight thousand
as well is one of the recommended sample
rates for YouTube videos. So let's just choose this. Next. Let's select our audio host. So this is the interface between Audacity and the sound device. If you're on Mac, it should
so-called audio up here. If you're on
Windows, I recommend selecting windows WAS API. This driver will give you less latency or recording delay. I recommend choosing Windows WAS API if you're a Windows
user in this box here. But for Windows users, if you experience any issues
when recording, it could try another driver as well to see if that
resolves the issue. Okay, next we have the
microphone inputs. So you can click on here and
select your audio interface. My mic is plugged
in this one here, Claret for pre USB. If you're using a USB mic, it should appear here as well. Going along, we can choose whether we want our
recording to be a mono or stereo microphone I'm speaking into right now
is a mono microphone. So I'm going to select
number one, mono. Also for most voiceover mix, the microphone will be mono. So if you are using a mono mic, I recommend selecting mono as a file size will be smaller. Some microphones for recording
music may be stereo, but generally microphones for podcasts or voiceovers
will be Mono. So I recommend
selecting mono here. Next we have the audio output. Here you can select where
you want to hear your audio. Headphones or speakers are
plugged into your computer. You could select
Built-in output. Or if your headphones
or speakers are plugged into your
audio interface, you can select your audio
interface from here. However, as I'm recording
this screencast tutorial, I'm going to select
the top one here. Okay, now let's monitor our audio to make
sure it works fine. So we have this
button up here that says Click to start monitoring. So let's click this now. And now you can see the level on the audio meter
when I'm talking. We never want this
to go above 0 dB. Because if it goes above 0 dB, it will clip or
distort our audio. And this won't
sound good at all. Generally, I want
my audio around about minus 12 and on the peaks or the loudest
points to be below minus six and
definitely below 0. If you order as too loud, you can turn it down on
your audio interface. Or if it's not
quite loud enough, you can turn up on
your audio interface. We can always turn
the audio up after, once you've recorded it, we wanted to make
sure it doesn't clip when we're recording. Depending on what type
of mic you're using, you may be able to turn down your microphone input
of this slider here. As I'm using an audio interface, it won't allow me to do so. Can change the gain on
my audio interface. Okay, so now we're all
set up ready to record. And in the next video
we're going to be recording audio into Audacity. Thanks for watching and
I'll see you there.
15. Recording Audio into Audacity: Okay, so now let's record
audio into Audacity. Before we record,
Let's make sure our microphone is in
the correct position. And let's also make sure our notifications and
emails are turned off. And it also recommend
putting your phone on airplane mode when
you record audio. I also recommend doing a
test recording in there. Everything is working fine before we do our
proper recording. Okay, so I'm going
to press Record now and do a test recording. Okay, So this is
a test recording. This is an example of the audio. And then I press Spacebar
to stop the recording. And let's play this back by
hitting the play button here. Okay, so this is
a test recording. This is an example of the audio. Okay, that sounds fine. I'm just going to undo
that recording by pressing Command Z on a Mac or
Control Z on Windows. Okay, I'll also recommend recording some room
sound as well. I'd normally record around five to ten seconds of the room. So I hit record and
then I'll be silent. And that way I recall the
ambience of the room. And this can be useful for any noise removal plugins or
effects when mixing audio. Okay, So let's recall the
actual recording now. It can go up to the
transport controls here and hit the
record button or use the key command R.
Remember I'm also going to record around five to
ten seconds of silence. Then I'll start speaking. Okay, so let's do this now. The microphone and
speaking into right now is the electoral
voice are E2E. This microphone is very
popular for podcasts, register shows, and
voice-over work. Then I stopped the recording
by pressing the space bar. If we wish, we can record onto another truck by pressing
Shift and record. Okay, so now I am recording
onto another track. There again, I
stopped the recording by pressing the space bar. We can select either track by hitting the Select button here. Say for example, now we want
to record again at the end. We can just go up to the
record button again. And it will record at
the end of this track. Now if I stop the recording
and then record again, it will again record at
the end of this track. Again, I am recording. But if we have the
other track selected, it will then record at
the end of this track. But for now, I'm
just going to delete this truck by hitting
this expert in here. And we can make this
bigger by clicking and dragging at the
bottom of the wave. The larger parts of the
wave or the louder parts. And the smaller parts of the
wave are the quieter parts. Okay, So that is how you
can record into Audacity. In the next video, we're
going to be looking at some more features
of the software. I'll see you there.
16. Playback, Zoom, Undo + Saving in Audacity: Hi there and welcome to
this video where I'm going to show you some more
features of audacity. In this video, I'm going to show you different playback controls, zoom controls, the undo
feature and how to save. Let's first look at
playing back the audio. If we click on the
waveform here, you'll notice we have
this vertical line, which is also known
as a play head ruler. If I press Play now
it'll play back from this play head ruler
or vertical line. So the microphone and speaking. And we can stop playback
by pressing space bar. If I click over
here, for example, and then press Space-bar
again by just shows. It'll play from this
area here again. And it will record at that. Notice when they
play back the audio, it will always go back to
this play head roller. However, we can actually
pause the audio. So if I play about
now the spacebar, the microphone and speaking, and then I can pause the audio. And then if I un-pause
the audio again, it will continue from where
the audio was stopped. Right now is, we can also use the key command P to pause
the electoral votes. Can also click and drag
on this waveform here. This will now play
from the start of the selection and we'll stop
at the end of the selection. Notice when we hover
over to the right to have this right
finger arrow button. And we can click and drag to move the end of the selection. And if we move over to the left, we'll have this left pointing
finger and we can click and drag this to move the
start of the selection. Now if I play this back, it
will start at the start of the selection and end at
the end of the selection. This microphone is very
popular for podcasts. However, we can actually
loop this back. So it continued playing
round and round until we stop by holding down Shift
and then pressing Spacebar. This microphone is very
popular for podcasts. This microphone is very
popular for podcasts. This microphone, and it'll continue going round and
round until we pause. This can be useful for
mixing audio if you just wanted to hear one particular
part over and over again. For editing and mixing, we may also wish to zoom in
and zoom out on the waveform. We can go up to the
zoom buttons here. So we have the plus button
which will zoom in, and the minus button
which will zoom out. We also have key commands
that we can use for zooming. So we can zoom in
with Command on Mac or Control one on Windows. We can go back to the
original position by pressing Command or Control on Windows. And then we can zoom
out with Command free or control
three on Windows. Let's just go back to
the original position. We have Command T on Mac
or Control T on Windows. We can add new tracks by going
up to Tracks, Add Track. Here we can choose
the type of track, but for this, I'm just
going to choose mono track. Like I showed you previously. We can select the tracks here. If we wish to record this track, we need to make sure
this is selected. But if we want to record
on the first track, we need to make sure this is selected and we can
mute or solo the track. So with these buttons here, we can delete attract
with this X button. And you can undo by
pressing Command on Mac or Control on Windows. And you can redo by
pressing Control Y on Windows or Shift
Command Z on a Mac. We also can go up to View, and from here we can
go to our history. This we can go to a previous
point of our project. However, if we go back
and then make a change, we won't be able to
go forward for this. I'm just going to go
back to where we were. Okay, and now let's
save our project. We can do this by going to
File, then Save Project. Or we can use a key command, command S on Mac or
Control S on Windows. You may have this
pop-up box appear, which means you're saving
the audacity project. You're not saving the
individual audio file. If you want to use
your audio file in another application, you will need to export
the audio from audacity, but we'll be looking at
there soon enough for this. I'm just going to hit Okay. And then name is Project. And then choose a
location and hit Save. Okay, so that's some more
features of all dusty. In this video I've showed you a different playback controls, zoom controls, undo
features, and how to save. In the next video,
I'll show you how to export your audio out of all dusty so you can open this audio in another application
if you wish. Thanks for watching, and I'll
see you in the next one.
17. Exporting Audio out of Audacity: Okay, So in this video
we're going to be looking at exporting your
audio from Audacity. You can add it and process
your audio in Audacity. However, if you just want
to use Audacity to record your audio and then edit or process or audio in
another application, then you can just
export your audio out of Audacity once
you've recorded it. In the next few videos, I will be showing you
the essentials of editing and processing
your audio. But let's now have a
look at exporting. You can choose to either
export a selection of your audio or export it all. Just be aware though
if you have any tracks so load or muted
when the export it, there will be so load
or muted as well. Okay, so just for this example, if I've selected the
selection tool and I click and drag over this
selection of audio, I can export just the selection. To do this, we
need to go over to File and then go down to Export. And here we can export
the selected audio, which will just export
this area here. However, if we want
to export all of the audio that we wanted
to select, Export Audio. For this though, I'm just
going to export the selection. I'm going to choose
Export Selected audio. You can obviously name
your audio file here. And you can choose a location you want to save here as well. Going down with how file type. For file type, you
want to choose WAV as this is a universal,
uncompressed audio type. Aiff is uncompressed
and fine as well. But wherever is a standard, so I recommend choosing this. I don't recommend
choosing MP3 as this will compress the audio and degrade
the quality of the audio, the file size may be
smaller with MP3, but it won't sound
as good as WAF. For encoding, I recommend
choosing signs 24 bit PCM. So PCM is uncompressed and 16-bit and 24-bit other
standard encoding bit rates. I recommend using
24-bit rather than 16-bit as if you mix your
audio in another application, then you may degrade
the audio slightly. If you're using 16 bit
rather than 24 beds. However, this may be
unnoticeable a lot of the time, and 16-bit still fine, but I recommend using 24 bit as it has slightly
higher quality. Okay, and then hit Save. Then you may get
this box appear, which is a metadata tags box. This is data that's
embedded into the file, which we'll show in places like iTunes or Windows Media Player. Stuff like artist's
name and track title. I'm just going to leave
all of this blank though. So if you just want to export
your audio out of audacity, so you can edit or processor in another application that you don't really need to
fill any of their sin. Now let's hit Okay. And this will export the audio. Depending on the length of your audio and the
speed of your computer, it may take a few
moments to export. Now let's go over to my desktop, which was the location where
chose to export the audio. You can see here we
have the audio file. Now let's play this back. The microphone and
speaking into right now is the electro voice RE2. And this microphone is
very popular for podcasts, radio shows, and
voice-over work. Great. And if we wanted to
export all of the audio, it's the same process, File export, but just select Export Audio instead
of export selected audio. And just follow the same
steps I just showed you. Okay, so that's how you can export your audio
out of audacity in case you wanted
to edit or process your audio in
another application. Like I said though, you
can still add it on process your order in Audacity, which we'll be looking at
in the next few videos. So recommend watching
these if you want to edit and process your
audio in Audacity. Thanks for watching, and I'll
see you in the next one.
18. Audacity's Essential Audio Editing Tools: Hi there. Welcome to this video where we're
going to be looking at some essential editing
features for Audacity. I'm going to show
the tools toolbar, which are these six
tools at the top here. So these six different
tools contain a lot of essential things for
editing audio in Audacity, This video will be useful if
you want to use Audacity, not just for recording audio, but also to edit your audio. This isn't a complete
audacity course by any means. I just wanted to show you the essentials in
case you want to use this free application
for editing audio. So here are two mono
audio clips from a recent music production
tutorial that I produced and the person speaking and this
recording is Ian Alexander. Okay, so now let's have a
look at the tools toolbar, which is this area
at the top here. This contains a lot of essential things
for editing audio. I'm going to show you what
these six different tools do. And I'm also going to show you the shortcuts for
each one of these. Let's first look at
the selection tool, which is selected by default. The key command is
slightly as tall as F1 on Windows or
function f1 or Mac. So we have looked
at this previously, but I'll go over it again
in case you missed it. So with this tool,
you can click and drag over a certain area of audio and it'll just play back this area, for example here. Now I'm going to play this back. So let's press the Play button. Also want to increase
the velocity of the bass drum throughout
this two bar loop. And you can hear that
the Audio stopped when it reached the
end of the selection. Now let's click somewhere else
to deselect the selection. Now let's have a look
at the envelope tool. So that's the second tool here. And the key command to
select this tool is F2 on Windows or
function F2 on Mac. You'll notice when we
have this tool selected, we have this blue line at the top and bottom
of the order clip. And we also have these
two gray areas are darker gray area and
the lighter gray area. If I switch back to the
selection tool by using the key command F10 or windows
or function F1 or Mac. You'll notice the
order clip looks different to when we have
the Envelope Tool selected. So let's go back to
that by pressing F2 or function F2 on Mac. With this tool, we can adjust the volume of an
audio clip over time. Let me just zoom in
on this clip here. Let's use the key
command, command one to zoom in or Control
one on Windows. And I'm just going to click
and drag at the bottom of this clip so we can say a
bit more of this as well. Okay, so when we have this
envelope tool selected, we can click to add control
points in this gray area. We can click and drag
these control points to adjust the
volume of the clip. So let me show you now. Let me just play this area here where we have this mistake. Also want to increase
the velocity. Says the word no there. So it can actually click to add a control point
around this area. Just this word. Now, I'm going to
reduce in volume. Let's actually remove
this breath as well. Let's click at the side there. And here again, we have
four control points. I'm going to click
and drag this down. And you can see this wave
updates in real-time. And we've actually
turned this area to silence and got rid of that mistake and the breath sound, Let's
hit this button now. I also want to increase. So let me adjust the volume
with these control points. You can see the waves
update in real time. Obviously the smaller the way
of the quieter the audio. This envelope tool can
be useful for adjusting the volume of your audio
clip at certain points. I'm just going to
undo that now we've Command Z or Control
Z or the windows. These changes will still be that even when we have
another tool selected. Let's go back to the
selection tool by pressing F1 or function F1 or Mac. You can see that we have
this lighter gray area. And if I play this
back, you won't be able to hear that
mistake that was there previously. Also wanted to. Okay, so now let's have
a look at the next tool, which is the pen tool. We can access this by using the key command or
function F ray on Mac, the pen tool, we can adjust the individual
samples of our audio. Let me show you this
by zooming again. Let's zoom in with
the key command, command one or Control
one on Windows. Me zoom in far
enough, you'll see the individual
samples of our audio. So these dots here are
our individual samples. Let me just zoom
out slightly with Command D or Control
D on Windows. Unlike I said, with this tool, we can adjust the
individual samples of our audio so we can change
the volume of the samples. And this might be
useful if there's a click or pop sound
and your audio, and you want to go in and adjust the volume of that one sample. So there's Pen tool allows us
to really dive in deep and adjust the volume automation
of the individual samples. We can also click and drag
to adjust multiple samples. I'm just going to undo
this day by hitting Command Z or Control
Z on Windows, I would normally
only use this tool though if there's
a click or pop or an issue where I need to change a sample or a few
samples in my audio. If you have a click or
pop sound in your audio, recommend zooming
in so you can see the individual samples and then try and fix this issue
with the pen tool. Let's zoom out back to our
original position by using the key command and command
or control T on Windows. Now let's have a look
at the next tool, which is the zoom tool. We can also select this by using the key Command F4 or
function F4 on Mac. This we can left-click to zoom in or right-click to zoom out. We also have the key
commands to zoom in and out. Command wanted to zoom in
or control one or Windows. Command on Mac or Control
a on Windows to zoom out. And then command
to or control T on Windows to go to the
default zoom position. Let's now have a look
at the next tool, which is the time shift tool. And we can slap this
with a key command F5 or function F5 on Mac. This tool, we can
move our audio clips. We can also move our audio
clips between tracks. For example, here
I'm going to move the audio clip from
track to track one. This may be useful if you
want to record an overdub on another track and then
move it to your main track. However, you can't
move stereo tracks to monitor tracks or monitor
tracks to stereo tracks. They have to be the same type of track to move around like this. So just bear that in mind. Now let's have a look
at the next tool. And this is the Multi-tool. And we can select this
with the key command F6 or a MAC function F6. The Multi-tool, we
can do a lot of the functions from the other
tools in this one tool. If you know how to use
this tool properly, it can save you some time
rather than swapping between the individual
tools for each task. So depending on where
your mouse cursor is, you may have different
functionalities for this tool. So for example, right now at the top part of the
audio where the wave, as you can see, the mouse cursor is the same as the
selection tool. I can click and drag
to select a section of audio velocity of the bass drum throughout this two bar loop. However, if I move my mouse
up to this blue line here, you'll notice the mouse cursor will essentially be
the Envelope Tool. You can click and drag
here to change the volume. Let me just undo
this now though. However, if we zoom
in on the audio, Let's use the key
command, command or control one or
Windows to do this. And notice we can see
the individual samples. Now if you hover over
the individual samples, you'll see we have the Pen tool. Let's just zoom out again with command or control T on Windows. Now if we press Command on
Mac or Control on Windows, then it will become
the time shift tool. You can click and
drag to move Eclipse. Okay, So that is the
Multi-tool and it basically combines a lot of
the other tools and one, okay, So that is the
six different tools from the Tools toolbar. In the next video,
I'll show more ways of editing audio in Audacity. I'll see you there.
19. Removing Silence and Splitting + Joining Clips: Okay, so now we're going to
look at removing silence as well as splitting and joining audio files and audacity. Let's first talk about
removing silence. Notice in this recording here we have this large bit of silence. Let me just play this back now. And every beat. Also want to increase. Previously we used
the Envelope Tool to actually lower the
volume here of a mistake. But let's go back
to the Slack tool. So it's quite easy to remove
silence and audacity. Or you need to do is use the select tool and
then click and drag on the area he liked to
remove and then hit Delete. Then it will delete the
area you selected and the rest of the audio will
snap back into place. Now if I apply this
back on every beat, I also want to increase
the velocity of this can be useful for moving mistakes or pauses
in your audio. For example, here
that looks like there's another
unnecessary pause. Let's have a listen back
up the same amount. Again. I could use the Select
tool click and drag this area and then hit Delete. Now in the play this back,
the pores will be gone. Same amount. So I want
to keep my great. You may also wish to split your audio clips and to
do this is quite easy. Just select the area
you'd like to split. And then wherever
this vertical line or play head ruler is, there will be a split
once you hit Command I on Mac or Control I on Windows. Now you notice we
have this black line. Now let's click
over here to access the time shift tool or
use the key command F5. And then we can click and drag
these parts independently. This might be useful if you've recorded another
part which you'd like to add in here or move
your audio clips around. You can easily do this
by splitting your audio. For example, I'm just going
to move this clip over, then this one over. And let's say we
wanted to split here. Let's go back to the
Select tool by pressing F1 or function F1 or Mac, and then select this area here, and then hit Command I to
split or Control I or Windows. And we split this audio here. Now we can go back to the
time shift tool by hitting this button using
the key command F5. And we can move this
audio into the gap here. And I can move this
one over again. May wish to get rid
of this gap here. So let's go back
to the slip tool. So let's hit F1 to
access the Select tool. Click and drag over this
area and now delete this. Okay, so that is
how you can split audio and also remove silence. We can also make our
Eclipse a bit more organized by joining
our clips together. To do this, just make sure you click and drag with
the selection tool, either clip you're like to join, and then go over to Edit
clip boundaries and join. You can see there
that black line has disappeared and this clip
has now been joined. Just for another example, let's join these
two clips together. So click and drag each clip
with the selection tool. Go up to Edit clip
boundaries and join. Okay, so that's how you
can remove silence as well as split and join your
audio clips in audacity. In the next video, we're
going to be looking at some essential
keyboard shortcuts or key commands in Audacity. I'll see you there.
20. Audacity's Essential Key Command or Keyboard Shortcuts: Okay, so now let's
have a look at few essential keyboard shortcuts or key commands for Audacity, we do of course
have the basic ones that we have for
most applications, such as select all command a on Mac or Control a on Windows. On do we have commands that on Mac or Control Z on Windows? Redo a shift Command Z or
Mac or Control Y on Windows. And of course copy command C on Mac or Control C on Windows. And paste command V on Mac, or Control V on Windows. I'm just going to undo
what I did there. We have Command Z on a Mac or
controls that are windows. And delete, which we
looked at previously. We can select the area we'd like to delete with
the select all, delete this, and then the audio will snap back to
fill in the gap. Again, I'm just
going to undo this. We have Command Z or Mac
or Control on Windows. This isn't a key command, but I'm just going to show
fade in and fade out as well. I'm just going to
select the area at the end and then go
over to effect here, go on, fade out. We also have fade
in here as well. You can see the audio gradually
fade out here at the end. By just want it to be
a bit more powerful. Again, I'm just
going to undo this. We have commands at, at the start we can fade
in, for example. Again, let's go to Effect and theta velocity of the
bass drum on every beat. Again, I'm just
going to undo this. Fading in and fading out. Maybe more useful for music
rather than spoken voice, but that's how you can do it. And other key commands
is spacebar to play from the play head or vertical
line. So I'm going to slip. And we can loop the playback by pressing Shift and spacebar. So if we have an area
selected like this, we can loop this playback
with shift and Spacebar. I'm going to select all the
bass drums by clicking. So I'm going to select all
the base and we compose of b. Bye. And of course we can't record
with a keyboard shortcut. We can jump to the
start of the track with J velocity of the bass drum. We can jump to the end
of the track with K. And of course we have
the zoom controls which we looked at earlier. Command on Mac or Control
a on Windows to zoom in. Command T on Mac, or Control on Windows to go to the
default zoom amount. And Command D on Mac, or Control D on
Windows to zoom out. You can also zoom
in or zoom out. So the entire order
of your project fits on the screen by
using the key command, command F or Mac or
Control F on Windows. And of course we can save wave Command S on Mac or
Control S on Windows. And another essential
key command is exporting your audio. You can do this on Mac
with Shift Command a or Control Shift E on Windows. That is some of the
main key commands or keyboard shortcuts
for our Udacity, I hope you found
this video useful and I'll see you
in the next one.
21. Removing Backing Noise Introduction: Okay, So previously we looked at recording and editing
audio in Audacity. And now in the next few
videos we're going to look at processing the audio by looking at removing the
background noise. So ideally, don't want to have any background noise
in your audio. Rarely you want to record
in a place that's quiet. However, that's not
always possible. In the next few videos, I'm going to show
you how you can remove background
noise and audacity. I'll be showing
you the noise gate and also the noise reduction. In fact, these are two different types of
noise removal plugins. And like I said,
ideally you don't want to have any background noise. But again, it's not
always possible. Here I have an audio recording that recorded for this example. When I play this back, you may notice that there is
background noise, in this case a fan sound. Okay, so this is me talking
into the microphone. This room is quite noisy. You may be able to hear that, that is a fan sound. So a fan sound like this is a very common noise that
hair on recordings all of the time of a common
signs that you may hear on audio recordings
could be an air conditioner, Sound radiator, or even traffic sounds
from outside the room. For the next few videos, I do recommend
wearing headphones or using good-quality
monitors or speakers. That way you can clearly
hear what I'm doing. Okay, so now let's
actually make a copy of this audio track so we can refer back to it once we
process the audio. Also, when you add an effect
to your order in Audacity, this change will be permanent. So we can't just turn on
and turn off the effects like an other digital audio
workstations or software. So the effect she
applied to your audio will be permanent in all dusty. Do recommend having a copy of your audio track is unprocessed. So you can always
go back to this if you ever make a mistake. Let's now sell out their struck
by double-clicking on it. And then duplicate by
pressing Command D on Mac or Control D on Windows. So I'm just going to select
the first track again. Let's click somewhere
that isn't on the track, and then double-click on the first track to select it again. Let's now duplicate
this top truck again by pressing Command D on Mac
or Control D on Windows. Scenario how free copies of this audio on separate tracks? Bond will be unprocessed, will have no effects. The next one will
have the noise gates, and the third one will have
the noise removal plugin. That way we can solo each track to hit the
changes that we've made. In the next video,
we're going to be looking at using the
noise gate effect. And in the video after this, I'll show you how to use
the noise removal effect. Thanks for watching, and I'll
see you in the next one.
22. Audacity's Noise Gate Effect: Hi there and welcome to this
video where I'm going to show you how to use
a noise gate effect. Before we do this though, I'm just going to explain what
a noise gate actually is. Noise gate as an
audio effect that reduces the audio
based on a threshold. If the level of the audio
drops below a certain level or threshold that we can reduce this audio that's
below the threshold. The threshold will
be in decibels. And when using a noise gate
and the level that goes below this decibel
level will be reduced. We can even reduce this
to silence if you wish. If the background noise
is above the threshold, then we won't be
able to reduce this. So if you want to
use a noise gate to reduce background noise, then you need to make
sure the threshold is above the level of
the background noise. However, if the
background noise is there whilst the
voices speaking, then we won't be able to remove just the
background noise. We can only reduce
the background noise when there isn't any speaking. If you want to remove
the background noise whilst the voice is
speaking at the same time, then you may wish to use
the noise reduction plugin, which we'll look at
in the next video. But this video, we're
just going to be looking at the
noise gate effect. This allows us to
reduce the level of the background noise when their silence or when their
voice isn't speaking. So before I add
any audio effects, I'm just going to rename track two and call this noise gate. That way we know that it's this track that has
the noise scale audio effect on
track to let's click on this drop-down menu
here and then go to name. And we're going to
rename this noise gate. One thing to mention before we continue Is if you're using an older version
of Audacity than it may not have the
noise gate audio effect. So if you can't find the
audio effects than the recommend downloading a
newer version of Audacity. Also, if you're using
Audacity free points 0, there was an issue with the
noise gate in this version. Again, if you're
using this version, I recommend downloading a
newer version of Audacity. Before I apply a
noise gate effect, I'm actually going to
normalize the audio. If I normalize the audio, is essentially going to
make it louder and it'll be a bit easier to see
the smaller sinewaves. Let's actually apply normalization
to all three tracks. So when I compare the tracks,
there'll be the same level. So let's select all
by hitting Command a on Mac or Control
a on Windows. And then let's go to Effect. Then let's go down to normalize. This will essentially boost
up the volume so it's louder. And we can also see the
sinewaves a bit clearer. I'm going to make
sure the second setting normalized
peak amplitude two is set to minus one dB. Remember you don't
want this above 0 dB or the audio clip. So I recommend leaving
this on the default minus one dB as this will give us
a bit of room just in case. Now let's hit Okay. You can see that
the audio waves are bigger and the audio is louder. Now let's solo truck do. And we can see the noise
here a bit clearer. If there's just a
horizontal line, then it will be
complete silence. But if there's any
waves on here, then there will be some sound. Let's just go to the
normal Zoom amount by pressing command to. We can even click to
drag this track down, make these waves a bit larger. You can see some
audio here and we don't have complete silence. So let's just hit
this button now. Okay, So this is me talking
into the microphone. This room is quite noisy. Obviously, you
could hear the fan sound that and the audio. Now what I'm going to do is
play back the audio again. But this time I'm going to
look at this audio meter over here to try and find
the level of the audio. There was a spike in audio here where I hit the microphone, but the fan sound audio
level was around 40 dB. Let's remember this number. Let's now just click off the tracks and then double-click to select
the only truck to. Then I want the audio to
actually start around here. When I play back the audio
or preview the audio. And the effect is
going to start around eight seconds rather than
right at the beginning. That's because an effect we can only preview back five seconds. So we will just be playing
back the room sound. And I want to play back the
room sounds and the voice. So if I hover my mouse over to the far
left of this track, you can see the mouse icon has turned into this
finger pointing left. Now let's click and drag this over to around eight seconds. Here we will have about
1 second of room sound, and then we will have the voice. This will only apply
the noise gate effect to the selected area. However, once we've
selected our settings, this will be stored
in the effect. So we can always
select the truck after and apply it
to the whole track. Once we find our settings, we can always apply
it to the whole track afterwards if we wish. Let's now add the effect. We can do this by going into effect and then go
down to noise gate. Let's first look at
the threshold and I'll show you the other
settings after this. Okay. So this is me talking
into the microphone. This room is we're cutting
off a bit of the voice. May need to decrease
this further. But just for this example, I'm going to put it really high. Let's try minus eight dB. So now when I preview this back, you'll notice it's going to get or reduced down in volume, the room sound and
also the voice. Okay, So this is me talking
into the market phone. This is obviously that
setting is way too high. But if we have it too low, that's going to let through
anything above this number. Let's play this back now
and you'll be able to notice that it's not
going to get efficiently, and it's going to let
all the noise through the gate as well as the voice. Okay. So this is me talking
into the market phone. This room is I believe
for this around about 38 db should
be fine. Okay. So this is me talking
into the microphone. This room is but just
to play it safe, I probably would have it
on a roundabout minus 40. Let's now have a look at
the settings up here. At the top we have
select function. For this setting, make
sure gate is enabled. The other option is
analyzed noise level. This basically does
what we did previously, wireless and back
to the room sound. And I had a look at
what the level was. So I don't actually
like to use this as I prefer to do it manually
like we did before. As a fine, we can
get better results. The next control
is stereo linking. If you're recording and stereo
than the gate will only be applied when both of the stereo tracks go
below the set threshold. However, I'm doing
this and mono. And if you're doing any
podcasts, tutorials, or voiceovers, that's
probably going to be a mono. The other option is
don't link stereo. If you have this enabled, then the trucks can be
gated independently when one of the
tracks goes below the threshold rather
than both of them? Like I said, you probably
going to be a mono. So don't worry too
much about this, but I live on the default
link stereo tracks. Okay, then we have threshold, which we looked at before. Let me just explain
what this is again, as this is a very
important setting, this will apply the gate only to the audio below this
level set here. This is on minus 40.1, is only going to apply
the gate to audio below minus 40.1 dB. However, if the background
noise was a lot quieter, and maybe this could be on say, minus 50 db as with
only gate the audio or reduce the level of the audio
that's below minus 50 db. When the audio goes
above the threshold, the gates will be opened
and the simul pass through. So it won't reduce
the order level. Any audio that's below this
level for Gates will be closed and the level of
the audio will be reduced. The threshold will
normally be around minus 60 to minus 40 dB, depending on the
level of your noise. For this example, the
noise is quite loud, which is why it's on
minus 40 or months 40.1 dB in this example. Next setting below as
gate frequencies above, this will apply the gates only two frequencies above
whatever you set here. This may be useful for moving some hairs and the
audio, for example. But Settings below 0.1 kilohertz will actually
turn off this feature. One thing to note, this
feature may introduce phase shifting or
issues in the audio. Don't actually recommend
having this enabled. I'm going to leave this at 0. As I don't actually
want to use this. Below this we have
level reduction. So this we can set how much of the gated part of the audio
will be reduced in volume. If you want complete silence, I recommend reducing
the level to minus 100 dB as this is
the lowest setting. Let me show you now. Okay, So this is me talking
into the microphone. This room is. However, you may not wish
to have complete silence, as you may wish to keep some
of the ambience of the room. Not having complete silence will also sound a bit more
natural as well. Having some level here may
sound a bit more natural and may sound a bit smoother for sections with and
without the voice. I recommend testing this around minus 30 dB and
adjust from there. Okay, So this is me talking
into the microphone. This room is okay. Now let's have a look at
Attack, hold and decay. The attack and decay is how fast the gate opens and closes. Basically, attack is how long it takes for the gate to open. And the K is how long it
takes for the gate to close once a signal has
come pass the threshold, and after any whole
time, if any, is applied, the whole time
is basically how long it takes the gate to remain open once the signal goes
above the threshold. So before the gate
starts to close. Adding hold may be useful if you're getting any low frequency sounds that prevent
the gate from closing between the
waveform peaks. For these settings, you
will need to listen back. And if you audio
sounds quite choppy, then you may wish to
increase the attack hold and the k times to make it
sound a bit smoother. Let's just increase
these amounts here just for this example. Okay, So this is me talking
into the microphone. This room is it took far too long for the gate to open and close with those times. So do you recommend
decreasing this? Okay. So this is me talking
into the microphone. This room. Is that sounded a
bit more natural. Bumps still going to
use a faster time. Let's try about this. Okay, So this is me talking
into the microphone. This room is sounded
a bit more natural, but it could hear the voice
we're starting to cut out. You may have to adjust this
threshold to make sure you're gazing just a background
sound, not the voice. Then you can adjust how much
you reduce the audio that goes above this level of
the level reduction here. And then you can adjust
the attack holding decay. So this is how long it takes
the gates open and close. I don't recommend
having this too low, but I recommend having
a small amount of time. So it doesn't sound too choppy. If you have this
setup correctly, than negate effect will only work on the quieter
parts of the audio, not on where their
voice is speaking. Okay. So once we're
happy with the settings, we can go ahead and hit Okay. You can see that and the
audio that the noise we had previously has
now been removed. Let me play this
back to show you. This is me talking
into the microphone. This room is quite noisy. May be able to hear that
there is a fan sound. Settings are fine. Remember
if you made a mistake, you can always undo by pressing Command Z on Mac or
Control Z on Windows. But I'm just going to redo
this with Shift Command on Mac or Control Y on Windows. When the voice isn't speaking, the fan sound has
reduced in volume. However, when the
voice is speaking, still a fan sound, but the background sound can be masked when the
voice is speaking. If you want to remove
the background sound whilst the
voice is speaking, then you may wish to look at using the noise removal effect. We'd be looking at this
in the next video. Okay, so that is the noise gate. And this can be
useful for reducing any sound in-between where
the voice is speaking. In the next video,
we're going to be looking at a noise
reduction effect. Thanks for watching,
and I'll see you there.
23. Audacity's Noise Reduction Effect: Hi there and welcome to this
video where we're going to be looking at the noise
reduction effect. So previously we looked
at the noise gate effect, which allows us to reduce
the background noise when the level is lower than what we're set with
our threshold. The noise reduction
effect, however, allows us to remove
the noise throughout the audio, including
whether speaking. If you want to use this
effect on your own audio, I recommend recording
just the room sound to effectively
use this plug-in. If you haven't
recorded and the room sound at the start
of your audio, then you can always
find sections in your audio where there's no
speaking and try and use that instead for the
noise reduction effect to remove this background sound, it really needs to
be a constant sound like a computer fan for example. So the noise and this
recording is a fan, constant noise, not
spikes of audio. For example, here, we could remove the constant
noise starts, but we couldn't remove
this spike of audio. Okay, so now let's actually
solo the third track. Now I'm just going to click on this drop-down box above
and then go onto name. And let's rename this
to keep organized. And let's call this
noise reduction. Let's have a listen
back to this clip. You can hit the Start there
we have the background sound. So I'm just going to click and drag over this background sound. This is important for the
noise reduction effect, and I'll show you this now. So let's go up to Effect and then go down to
noise reduction. We actually have two
steps we need to do in this noise
reduction plugin. The first step here says select a few seconds of just noise. So audacity knows
what to filter out, then click Get Noise Profile. So that's why I did I
selected a few seconds there. It doesn't have to
be as long as this, but I do recommend
a few seconds. Let's now get noise profile. Notice the plugin is closed.
It's meant to do that. Now we need to go back up to Effect and then down to
noise reduction again. Now we're on step two. Now we can preview the audio that plays back
for five seconds. You can still hear the fan
sign, but it's not as loud. I'm just going to move
the mouse over to the left and right of
this highlighted area. So this finger icons appear. Just move it over here. So we got around a second of silence and then we
can hear the audio. When we apply, this effect is only going to be
applied to this area. However, after I've showed you the settings of this
noise reduction effect, I'll show you how to apply
it to the whole track. Let's make it a bit longer
at the end as well. Now let's go back to
effects and then down to noise reduction. And
preview this again. This is me talking
into the microphone. Let me just move this out of the way so we can
see what's going on. Okay, So this is me talking
into the market phone. Okay, now let's look
at the second step. The first setting here
is noise reduction. So this allows us
to select how much we want to reduce the
noise in decibels. Higher values will
reduce the noise more, and lower values
will reduce it less. However, if you
reduce it too much, then it may ruin the
quality of your audio. So I don't recommend
setting this to high. But just for this example, let's increase it
all the way to max, which is 48 decibels. Now abbreviate this back. Okay, So this is me talking
into the microphone. You may have heard that that the voice recording
wasn't quite as clear, but a lot of the background
noise was removed. But for this, I'm going to
drop it down to 12 again. Now let's talk about
sensitivity going down. And we have this
sensitivity slider. So the higher the value here, the more noise that
will be removed. So just remember the
settings that you apply here is applied to
all of the audio. So where the voice speaks
and where the voice isn't speaking, their
sensitivity slider, I recommend choosing between 15 as if you have
this set too high, then you may ruin the
quality of your audio. But just for this example again, let's use an extreme
one. Let's go up to 24. Okay. So this is me talking
into the microphone. You may have had there. It
did ruin the voice slightly. So let's drop this down a bit. I'm going to choose four, and let's preview this back now. This is me talking
into the microphone. We may have some issues or artifacts when applying
noise reduction. If you do experience this and I recommend adjusting
the sensitivity. And you may also wish to adjust the number of smoothing balance. Adjusting these bands is also
going to adjust the sound. So be careful as it may damage the quality
of your audio here. So make sure you use your
air for this one as well. If you do have any issues when
applying noise reduction, you may wish to increase
the number of bands. The default is free, but you can try higher
values if you need. So after pressing
preview and you can hear some artifacts are
issues in your audio. Then you may wish to increase the frequencies moving bands as this will spread
the noise reduction into neighboring bands. So this may smooth
out the artifacts and make them sound
more acceptable. However, again, if
you set this to high, then it may make the
audio sound less clear. But just for this example, let's try and extreme
setting again. This is me talking
into the microphone. Okay, it didn't sound too
bad of this high setting. But I'm going to go back to
the default which is free. This is me talking
into the microphone. Okay, let me now talk
about reduce and residue. If you have reduced enabled
and this will filter out or reduce the noise from the
audio that we have selected. When you press Preview, you can hear the audio
with the noise removed. However, if you have
residue enabled, then this allows you to hear only the audio that
you wish to remove. Just the noise that
you wish to remove. If we have residue enabled
and we listen back with a preview button and we can hear some of the
voice in the audio, then we know that
noise removal is removing the voice as
well as the noise. If that's the case,
then I recommend going back to the
above settings to adjust these so you can't hear the voice as much
in the playback. Let's have a listen back
with this on residue mode. We can hear a bit
of the voice that, but it doesn't sound like
too much of a problem. However, if I increase
sensitivity to max and then preview this back, you can hear that more of
the voice and the audio. So I recommend decreasing this as a voice may
sound a bit unclear. Recommend going between residue and reduce and finding
that sweet spot. We are moving the noise
but you're not damaging the voice too much. Okay. So this is me talking
into the microphone. We can still hear the
background noise, but again, at the background noise is quite loud and you tried
to remove too much, it may damage the
quality of the voice. Do reduce, say, 20 decibels. That increases
sensitivity slightly. You'll notice
there'll be less of the background noise and the audio won't be
quite as clear. Okay, So this is me talking
into the microphone. Of course, we can smooth this
out a bit more if you wish. This is me talking
into the microphone. It doesn't sound too bad, but if I do so
that residue here, you'll notice will be able to hear quite a lot of the voice. For this example, I'm just
going to drop this to 12. Let's put the
sensitivity on sex. Let's put the bounds
on for residue. You could still hear the voice, but it wasn't too loud. So let's change the mode back to reduction and let's
hear this back. Okay, So this is me talking
into the microphone. Not perfect, but it's
more acceptable. Now let's hit Okay. You'll notice that has
removed the background noise. As we can see, that
wave has disappeared. Now let's play this back. Okay, So this is me talking
into the microphone. As I just highlighted this area here is only going to
remove the noise from here. But if you want to
remove the noise from all of your audio, what you can do is undo
this by pressing commands, add on Mac or
Control on Windows, and then double-click on this
audio track to select all. Then go back to Effect, then go down to noise reduction. You can see that
saved our settings. And it's also saved the
noise profile from before. Now we can hit Okay,
and it'll apply this noise reduction to
the entire audio track. Now let's play this back and
hear what this sounds like. Okay, so this is me talking
into the microphone. This room is quite noisy. It may be able to hear
that there is a fan sound. Of course, we can still
hear the background noise. But if we compare it to
the original recording, you'd be able to hear
is a lot quieter. Okay, So this is me talking
into the microphone. This room is quite noisy. It may be able to hear. This is above the
noise reduction. Okay, So this is me
talking into the market. This is where the noise gate. This is me talking
into the microphone. This is the unprocessed audio. Okay, So this is me talking
into the microphone. Recommend learning how to
use the noise gate and the noise reduction effect and then apply them to your
clips if you need to. You can also try using
both the noise gate and the noise removal
plug-in at the same time. But to be honest, if
you want your audio to sound as good as possible, you want to try
and record it with as little noise as possible. If you do have any background noise that you wish to remove, I recommend using the
techniques or taught you and applying them
to your own audio. Noise getting maybe
more preferred as it doesn't actually
damaged the audio. It just turns down the audio at the quiet parts to help
remove the background noise. However, the noise
removal effect can remove the unwanted
noise whilst speaking. And also whilst
there's no speaking. It really depends on
which his best for you. But like I said,
ideally wanted to record out any background noise, but that's not always possible. Okay, So that is the essentials of noise reduction in audacity. In the next few videos, we're going to continue looking at processing the audio
with EQ and compression. I hope you found
this video useful and I'll see you
in the next one.
24. Introduction to Mixing and Processing Audio in Audacity: In this next section, we're going to be talking about applying audio effects and processing audio in Audacity to help improve how
the voice sounds. If you want to follow along
with me in this video, then be sure to check out the
downloadable resource which you can access in the
resources area of this class, which is in the projects and resources tab below
the video player. This is also the same
order file that we were looking at in the editing
section of this course. But you can actually apply the techniques I'm
going to teach you in this section
to own audio clips. You can follow along with me
with the exact audio clip. Before we get started, let's duplicate this audio
track so we can quickly AB or competitive pieces of audio
while we're mixing. So I'm just going
to double-click on the track header here
to select the track. Then I'm going to
press Command D on Mac or Control D on
Windows to duplicate. You can see here it's
duplicated this track. We also have this empty
track in the middle here. I'm just going to delete this by pressing the X button
on the track header. Just to keep things organized, I'm going to name
both of these tracks. On the track header here,
the small arrow button. I'm going to click on
that and then press name. If attract to this will
be the original audio. So the unprocessed audio, I'm going to call
it on processed. And track one will be the
track that has the effects. So let's click on
this arrow button on the track header,
then go to Name. And for this I'm going
to call this process. We can call this
whatever you like. Now I'm just going
to double-click on the top tracks header here. Just so I select only this track as we don't want the track to select it because
I'm not going to add any effects to that track. Also, when we add
effects to Audacity, these changes are destructive. That means when we
add an effect is actually going to burn the
settings into the audio. We can press Undo, but we can't simply turn
the effects on an afloat. We can add other
pieces of software or digital audio workstations. That's another reason
why we want to keep the original audio track just
in case we make a mistake, we can always go back because we have the original track here. I also recommend using
high-quality monitors or headphones to monitor
your audio for mixing. Mixing changes can
be quite subtle. So you really want to be able
to hear the audio clearly. Like I've said
throughout this course, if you have really
bad quality audio and applying effects and processing
the audio weren't ready. Fix this. You want to make sure your audio is recorded well to start with. Then we can improve
this by adding effects. In the next few videos,
we're going to be looking at EQ and compression, which are really the
main effects for mixing. Thanks for watching, and I'll
see you in the next one.
25. A Brief Look at the Filter Curve or EQ Effect: Hi there and welcome to this video where
we're going to be looking at EQ or equalization. We have two different
types of EQ in Audacity, graphic EQ and filter curve. Graphic EQ allows us to adjust
fixed frequency bands and filter curve allows us to have more control over
adjusting frequencies. For this example, we're going
to choose Filter curve. Let's apply this to our track. Let's make sure
we have our track selected and then go to Effect. Then go down to filter curve. If filter curve is
essentially a parametric EQ, but they call it a filter
curve in Audacity. Eq or equalization essentially allows us to adjust the volume
of different frequencies. We can use this EQ to
change the sound or just a frequency balance
of the voice if we wish. On this EQ vertically we have volume and this is
in decibels or DB. We can increase the volume with positive values or decrease the volume we have
negative values. And 0 dB is a level
of the audio. Before we've applied the EQ. Horizontally, we
have frequencies, so we have the lower
frequencies on the left and the higher
frequencies on the right. So this goes from 20 Hertz
to 20 thousand hertz. The human range of the
voice is generally around 100 to 8 thousand hertz. But again, it depends
on the voice. And the human range of
hearing is anywhere from 2220 thousand hertz, which is why this EQ goes
from 20 to 20 thousand Hertz. We also have these grid lines, which can be useful if you want to find exact frequencies. However, you can uncheck, Show grid lines down here if
you want to turn them off. But I find it useful
to have them up. So we can actually draw in different breakpoints on
this EQ by just clicking. Then these nodes will appear, which we can click and drag. For example, here I've made
a boost around 1000 Hertz. You can always go back to
default by pressing flattened. This will reset all the
changes you've made on the EQ. So the line will be
horizontal at 0 dB. If you just click above
like this and you'll have this horizontal line is just going to make all of
the frequencies louder. You will have to click to
add more breakpoints if you want to just boost or
cut certain frequencies. Let's add a few more
bright points around this. For example, here we're
boosting around 1400 hertz, or it can click and
drag down to cut or attenuate around 1400 hertz. We also have this
invert button here, and this will flip the
shape that was created EQ. Be honest though, I wouldn't
really use this feature. It isn't really that useful, but it's there just in case. Okay, so let's just
play the audio back now and then I'll make some extreme changes so you can clearly hear the difference. Let's go back to flatten and then preview this audio back. Also want to increase
the velocity of the bass drum on every beat. I also want to increase the
velocity of the bass drum. Now let's click the ads and breakpoints here
and I'm going to make an extreme boost and
the high frequencies. And let's play this back
by pressing preview. Also want to increase
the velocity of the bass drum on every beat. I also want to increase the
velocity of the base stroke. Obviously that is too extreme. It could hear the higher
frequencies were a lot louder. Now let's do the same
with the low frequencies, clipped out breakpoints
and click to drag this up. Also want to increase
the velocity of the bass drum on every beat. I also want to increase the
velocity of the base stroke. That is a bit more subtle
as a voice isn't as low. Let's try adding the shelf here, but for more low
mid-frequencies. Also wanted to increase
the velocity of the bass drum on every beat. Also want to increase the
velocity of the bass drum. That's a lot more obvious. Let's attenuate this now. It also wants to
increase the velocity of the bass drum on every beat. I also want to increase the
velocity of the base stroke. And let's press flattened again. And never extreme example here. That's attenuate the
higher frequencies by adding their shelf here. Also want to increase
the velocity of the bass drum on every beat. Also want to increase the
velocity of the bass drum. Let's go back to flatten. Now let's make some changes
that may be more useful. So I'm actually
going to filter out some low frequencies as
this goes to 20 hertz here, but the voice will not
be speaking this low. The only audio, a
big guessing that this lower frequencies here
will be low rumble noise, so we can filter or remove this. I'm going to collect, add
some breakpoints here. Then I'm going to start my
filter around 30 hertz. I'm going to preview
this back now, but the changes may
be quite subtle. Also wanted to increase
the velocity of the bass drum on every beat. Also want to increase the
velocity of the bass drum. You can hear though we went
actually filtering the voice. We would just
filtering any audio that was lower than their voice. Let's do the same, but for
the higher frequencies. So the higher frequencies here weren't actually be
the voice either. This may just be
some high-end noise. So let's filter out the
high frequencies again. Let's click to add a breakpoint. Then I'm going to filter
around 16 thousand hertz. I could probably move this
filter even lower to say, around 12 thousand hertz. But just to keep it safe,
I'm going to leave it here. The filter starts around
17 thousand hertz. Again, I'm going
to play this back, but the changes will
be very subtle. Also want to increase
the velocity of the bass drum on every beat. I also want to increase the
velocity of the base strokes. I'm also going to
add slight boost in the low-end, around 80 Hertz. I'm going to add a boost. So I'm going to click
the Add three nodes, and then the middle node
here I'm going to boost. Again. This may be quite subtle, but you may be able to hear a slight boost in the low-end. Also want to increase
the velocity of the bass drum on every beat. I also want to increase
the velocity of the bass drum can be useful
to make more extreme changes. So you can hear that
exact frequency and then pull it down to taste. But let's hit this back butt. This more extreme change. Also want to increase
the velocity of the bass drum on every beat. Also want to increase the
velocity of the bass drum. Let's put this down to around
five dB and play this back. Also want to increase
the velocity of the bass drum on every beat. Also want to increase the
velocity of the bass drum. Okay, I'm going to make
another boost now. But this time in these
high frequencies, I feel like the voice could
be a little bit brighter. Let's have this
band a bit wider. So around three to
6 thousand hertz. And then Adam node in
the middle and increase this, maybe even wider. Let's preview this back. Also want to increase
the velocity of the bass drum on every beat. I also want to increase the
velocity of the bass drum. Okay, That sounds nice. It might make this even wider. And just for this example, I'm going to boost it even more so you can clearly
hear the difference. Also want to increase
the velocity of the bass drum on every beat. Also want to increase the
velocity of the bass drum. And let's drag this
down to around about three dB. And let's
hear this back. Also want to increase
the velocity of the bass drum on every beat. I also want to increase the
velocity of the base strokes. We can make this even
wider if you wish, but I think it
sounded pretty good. Also wanted to increase
the velocity of the bass drum on every beat. I also want to increase the
velocity of the base stroke. I'm going to have
this boost start around 2.5 thousand hertz. That's some realistic changes
and they add to this audio. If you want to clearly
hear the changes back, I recommend starting
with extreme values and then moving them up or down to something more realistic. This audio was
recorded quite well. So I'm just making some
slight improvements here. But you can also EQ if
you have any problems, if there's a certain frequency
that's causing you issues, you can try and find the
frequency in the spectrum here and trying to
attenuate it or reduce it. But really you want
your audio to be recorded well and
to sound as good as possible before you add
any effects as adding effects to poly recording audio isn't always going to fix it. I also recommend not EQN
just for the sake of it. If your audio already sounds fine and the frequencies
are already balanced, you don't need to
make any changes. However, for this example, I think these few changes
didn't prove it slightly. Okay, another thing I want to mention is these sliders here. These allow you to zoom in positive values or
negative values. This can be useful if you
want to have a closer look. We also have this
checkbox down here that says linear
frequency scale. I recommend leaving
this unchecked as it allows you to add a bit more
detail in the lower ends. Notice here the frequencies
are equal distances. But if you uncheck this,
they're not at equal distances. But this allows you to add a bit more detail in a low-end. So I do recommend
having this unchecked. Remember you can
always go back to the default by
pressing flattened. But if you are happy
with your changes, I recommend actually
saving a preset. We can save a preset by going to manage and then go
down to Save Presets. I'm just going to
call this example. Now if I just flatten this, I can load that preset. Let's go to Manage and then
go down to User Presets. And here we have example. Go back to manage. We
actually have a number of different factory
presets as well. If we go back to Manage and
then go into factory presets, you can see here, audacity
has provided some presets. For example, let's
choose this one here. I AM radio. You can see that it's
filtering out a lot of the lows and the highs. But they do recommend adjusting the settings manually rather than using some of these presets that Audacity has provided. Let's go back to the preset
that we made by going to manage user presets and then
selecting it from here. Creating your own user preset
can be useful if you're recording with the
same equipment and in the same
room as next time, you can just load
this up instead of making it every time. Okay, so now let's
actually apply this to our audio
by hitting Okay. Now if I started this
track and play it back, we have those EQ settings
that we made applied to this audio piece of velocity of the bass
drum on every beat. I also want to increase
the velocity of the bass drum throughout
this two bar loop. So I'm going to select all
the bass drums by clicking. If I click and drag one of them. That is the EQ effect. In the next video,
we're going to be looking at the compressor. Thanks for watching,
and I'll see you there.
26. A Brief Look at Compression and the Normalize Effect: Okay, so the next
effect I'm going to apply to this audio is
the compressor effect. So a compressor effect turns
down the louder parts of the audio and then allows you to turn up the overall
level of the audio. This essentially
compresses or squashes of sine waves to give your
audio less dynamic range. This will stop the louder sounds jumping out in your
mixed too much. And it will also
increase the volume of the quieter words. So it's easier to here. This will turn down the volume of the louder sounds
or the louder, whereas in your audio. And it will also increase the quieter sounds or quiet,
uh, whereas in your audio, making them easier to here, I can press or effect is
very common in mixing audio, and especially for mixing voice. Okay, so let's make sure we have the top track
selected again. And now let's go to Effect
and then down to compressor. Like I said, the compressor
effect basically reduces the dynamic
range of the recording. So the range between
the louder parts and a quieter parts
will not be as much. Okay, so now let's have a look
at some of these controls. And the first one I want to
talk about is threshold. This is a very important
control for this compressor. The threshold is a
level that the audio can reach until
compression is applied. If anything above this
level will be compressed and anything below this level
will not be compressed. For example, right now
is our minus 15 dB. So anything above minus
15 dB will be compressed, and anything below minus 15
dB will not be compressed. Just for this example, let's put this to minus 12 db. And I'm just going to uncheck this makeup gain box down here. I'll explain what
that does later on. But now when I play this back, anything above minus 12 here on this meter
will be compressed. Let's just play this back now
with this preview button. Also want to increase
the velocity of the bass drum on every beat. I also want to increase the
velocity of the base drive. Change this to say minor six. And Ethan above minus six
here will be compressed. You may notice this audio isn't actually going
above minus six dB, so none of the audio will
actually be compressed. Also want to increase
the velocity of the bass drum on every beat. I also want to increase the
velocity of the base stress. There. The compressor wasn't
actually doing other thing because the audio was
below minus six dB. But just for this example, if I put this to minus 30 db and the thing above minus 30 db
here will be compressed. Also want to increase
the velocity of the bass drum on every beat. I also want to increase the
velocity of the bass drum. I'm going to set
this to minus 12 db. As I don't like to
compress too much and I don't want it to still
sound quite natural. Okay. I'll explain what noise
floor is in a moment. But now let's talk about ratio, which is another important
control for a compressor. This is the amount
of compression that's applied to the signal. Once it's past the threshold. The higher the ratio, the
more compression that will be applied to the signal once
they exceeds the threshold. I personally like quite
natural sounding compression. For this setting. I wouldn't really
put it too high, sudden normally have
this around free to one. I wouldn't personally go
past about five to one. However, if you want
a more compressed and maybe radio
style compression, then you could always increase
this ratio if you wish. Let me explain what these
numbers actually mean. So it's called ratio because
we have these ratios. 2-to-1, 3-to-1,
4-to-1, five to one, all the way up to ten to one. The larger the number, the more compression
you are applying. Ten to one would apply more compression to the
signal than say, two-to-one. Let me explain what these
ratios actually mean. So let's start with two-to-one. So here if the signal goes above the threshold
by two decibels, there'll be reduced
to one decibel. Three-to-one means if
the signal goes above the threshold by free
DB, or three decibels, it will be reduced to one dB or one decibel and tend to one means if the signal goes ten decibels above
the threshold, it will be reduced
to one decibel. Essentially, the
higher the ratio, the more compression
will be applied to the signal that
exceeds a threshold. If you don't quite
understand those ratios, it doesn't really
matter too much. Just remember, the more
you increase this slider, the more compression
you'll be applying to the signal once it goes
above the threshold. Let's now hear an
extreme example. Let's drop the threshold to minus 30 db and then have
the ratio on ten to one. Any signal that's above
this number here minus 30. This will compress any
audio that's above 30 dB, our ratio of ten to one. Let's hear this back now. Also wanted to
increase the velocity of the bass drum on every beat. I also want to increase
the velocity of the bass drum that
is quite compressed, but it is quite quiet. What we're actually
doing is we're turning down the louder
parts of the audio, which makes the
overall level quieter. This is where this
makeup game for 0 dB after compressing
checkbox comes in handy. I'll explain attack and
release it in a moment. But let's now enable
this checkbox. If I play this back now you'll
notice is a lot louder. Also wanted to increase
the velocity of the bass drum on every beat. I also want to increase the
velocity of the bass drum. In a compressor, makeup
gain allows you to increase the gain of the
audio that you've compressed. Like I said, when you
compress your audio, your turning down
the louder parts. This makes the overall
level of the audio quieter. After you've
compressed the audio, you can increase
the overall level. We have makeup gain. So if you have this box enabled, it's essentially going to
increase the peak levels or the loudest parts
of the audio to 0 dB after it's
being compressed. Some compressors do
have a Dalloway. You can manually set
the makeup gain. But with this one, we
don't have a dial, we just have this chatbox. So it's kind of an
auto makeup gain, but we'll set the
peak level to 0 dB. Now let me explain what
attack and release time is. Attack times the time it
takes for the signal to be compressed once it's gone
above the threshold. So it's basically how long it takes for the
compression to kick in. I don't recommend
setting the attack time super-fast as the audio may
sound a little squashed. But I also don't
recommend setting a slow attack time as a compressor may not
work effectively. For this, I'm going to
leave it on 0.2 seconds, as there should be fine for
a spoken voice like this. Now let's talk
about release time. So the release time is how long it takes for
the compression to stop working or to go back
to the uncompressed sound. Once you go below the threshold, It's basically the
opposite of attack. Fast release time means a compressor will
essentially stop working as soon as the signal
goes below the threshold. And a slow release time means it takes longer for
the compression to stop working once the signal
goes below the threshold. The spoken voice like
this are generally choose quite a fast release time
as if the release time is too slow than the compression may not work effectively. I do recommend starting with quite a fast attack
and release times. And if you do hear any
issues with the compression, there may be try increasing
these to see if it helps fix any of those issues.
Let me know. I mentioned this
other checkbox which is called compressed
based on peaks. If we have this
uncheck, the compressor will compress a signal that sees a fresh hold and won't compress a signal
below the threshold. However, if we have this checked
than the compressor will increase the level of the
signal exceeds the threshold, less than the level that
doesn't exceed the threshold. It will boost the gain of
the signal that's under the threshold more than the signal that's
above the threshold. I like to have this unchecked. As if you have this checked, it's going to boost the
signal under the threshold, which I don't really want. For example, it may boost any background sound
that you may have. That leads me onto this
last setting here, which is noise floor. This level here is what the
compressor will not boost. Anything below this number
will not be boosted. This can be useful if you have any background noise that
you don't want to increase. Right now it's on minus 40 dB. So anything below minus
40 dB will not be boosted or made louder with the makeup gain
if we enable it here. So if there's something
like a computer fan or a Hesse and you're recording, then you can set the
level of the noise here so the compressor doesn't
boost that noise. Otherwise you may
end up boosting the noise level to
which is not ideal. Let me now adjust these settings to something a bit
more suitable. I'm going to change the
threshold to minus 12 dB ratio to three to one. And I'm going to leave
the attack on zero-point two seconds and then
release on 1 second. I'm going to make
sure this makeup gain chatbox is enabled. Now preview this back. Also wanted to increase
the velocity of the bass drum on every beat. Also want to increase the
velocity of the bass drum. Okay, great, we are, I
didn't compression there, but it is quite natural
sounding compression. If you do want to
compress a little more, it could always
reduce the threshold and increase the ratio. For example, let's change
the threshold to minus 15 and the ratio to five to one. Let's say this. But now also wanted to increase the velocity of the bass
drum on every beat. I also want to increase the
velocity of the bass drum. Okay, that sounds fine as well. I'm actually going to
save this as a preset. So let's go to manage, then go to save presets. We're going to call
this example more. Then I'm going to change
the setting to minus 12. You'll notice as well this graph updates when we
adjust the settings. Let's change this
to three to one. I'm going to save
this as a preset. So let's click on
Manage again. Presets. Call this example less. Okay, so now I have two
different settings. One setting with
more compression and the other with less. But for now I'm just going
to use this setting here. One more thing to mention is this question mark button here. If you check this,
it will take us over to the old dusty site, which will give us a
bit more information about the audio effect. Okay, so I'm actually going
to apply this setting now. I'm going to hit Okay. And you can see that the
audio waves updates. Let's now apply this
backward of the space-bar. Also want to increase
the velocity of the bass drum on every beat. Also want to increase
the velocity of the bass drum throughout
this two bar loop, going to select all the base. Okay, so one more thing to
mention is if you find your audio too loud after you've applied this compression effect, then you can actually decrease this level by using
normalization. So many people use a normalized effect to increase the level, but you can also use it
to decrease a level. Let me show you how
to do this now. Once your audio
track is selected, go up to Effect and then
go down to normalize. We can actually turn it down
here by maybe one or two dB. I'm going to make sure
normalized peak amplitude two is set to minus one
dB for this example. Now the peaks won't be at 0 dB, there'll be at minus one dB. You can see the audio waves
are a bit smaller now, and the audio will be a bit quieter. Let's now
play this back. The space-bar also
wanted to increase the velocity of the bass
drum on every beat. There we go. Okay, So in the last few videos, I've already covered
the essentials for processing and mixing audio. I've covered noise removal,
EQ, and compression. There is still more we can do in terms of processing and mixing. But I've covered the
essentials in this class. If you're recording in the same place with the same equipment, and then you can save
your settings so you can use them again in
the next recording. We can do this by
setting up a macro, and I'll show you how to
do this in the next video. Thanks for watching,
and I'll see you there.
27. Setting up an Effects Macro in Audacity: Hi there. Welcome to this video where
we're going to be looking at setting up and effects
macro in Audacity. Saving a macro will allow you to save your effects
ready for next time. This can be useful
if you record in the same room with the
same equipment each time. You can of course,
create your own presets in these effects and
then add the effects individually each time we're using an effects macro
can be a time-saver. I forgot to effect now. And that's the filter curve. You may notice we have
the same settings that we made in the
previous video. And same again if
I go up to effect, but this time choose compressor. Again, we have the same setting that we made in the
previous video. And same again with
the normalized effect that we looked at in
the previous video. Thus the keeps the
previous settings that you adjusted
in your effect. This is useful for
making a macro as it's going to keep their settings
that we adjusted previously. Let's now make an effects macro. And we can do this by going to Tools and then go
down to macros. Now we're going to add a
new macro by pressing New. You can name your macro here. I'm going to call this
example and then hit Okay. Now we need to actually add the effects so the filter curve, so the EQ, the compressor, and also the normalized effect. And we can do this
by going to insert. This does look a little complex, but only it's doing now is
just fine filter curve. And this is alphabetical. So let's go over to F, and here is filter curve. Now let's press
Okay to add this. Now let's go on Insert and
then find the compressor. Here it is. Let's press Okay. Now I'm going to add the
normalized effect as well. So let's go on inserts. Then go over to n For normalize. Here it is. And now let's press Okay. We're going to make sure
that's after the compressor. We can click on
these and use them. Move up, move down arrows. If we wanted to
change the order, this is order I want EQ
compression that normalize. So now I've loaded my Effects, I'm going to press Save
and now close this window. Okay, so now I'm going
to add this affects macro to the unprocessed audio. I'm going to
double-click to select this track and then
duplicate this. So we still got a copy of the
original unprocessed audio. So remember you can
duplicate with Command D on Mac or Control D on Windows. Now let's solo this
bottom track here. Then double-click on
this track header and then add this macro. And we can do this by going to Tools and then go
down to apply macro. And here you notice
we have our preset, which is called example. You can see that the
audio waves have updated and we've loaded
the filter curve effect, the compressor, and
a normalized effect. Now if I play this back and swap between truck three
and track one, notice they're exactly the same because we have
the same effects. Also wanted to increase
the velocity of the bass drum on every beat. Also want to increase
the velocity of the bass drum throughout
this two bar loop. That's how you can
apply an effects macro. So it saves you adding
the effects each time. However, if you're going
to be recording your audio of different equipment
or in a different room, then you may wish
to manually add your effects and adjust
them accordingly. But if you are recording
with the same equipment in the same room and effects macro can save you
a lot of time. That's the end of this video. I hope you found it useful and I'll see you in the next one.
28. Outboard Gear - The DBX 286s: in this lecture. I want to talk about a microphone pre amp on process er to. This is a piece of outboard gear that could be used to actually process on change ineffectual voice before it's even recorded. So the signal goes from the microphone into this pre AMP this process and then into your audio interface and then recorded in your d aaw, such as logic pro. So this allows you to actually make sure microphone before is recorded, so this could be very useful. Four situations such as live streaming way, obviously can't mix your audio. This could also be useful for people who don't mix the audio for creators who want to have the audio mixed just to save time. Effort. Energy. So I've got video here of my friends Sonny, who is an animator. He creates tutorials about animation, and he uses this mic pre amp process er, just so it doesn't have to mix the audio because it's not an audio engineer on. He just wants his audio to sound as good as possible without mixing. So I'm going to walk through the settings he uses so his audio can be mixed before it's recorded so I'm going to show on screen now. The settings were used for this pre amp. Just in case this is something that you might want to think about, especially for situations such as live streaming. I do personally prefer mixing my audio in post. I do think I can get it sounding slightly better then free this pre amp. However, for situations such as live streaming. Do you think this is an amazing bit of gear? So let's have a listen to this. So as I was going into the phone is, I was going into the far subjects. Motion design is in between graphic design special effects on here is their pre on bypassed . This is what is audio sound like before I think separate pass. So obviously has you can hear there's a lot of gains, so we have input gain here. Think of design is like the graphic design and the special effects. Some microphones might not provide that game as the Ari 20 so this could Adgate. We also have a compressor. Part of Martian design is much more so you can adjust the drive and also the density off the compressor is the sort of things that we don't really have an opinion on. It's kind of how we think we also have a high pass filter, the graphic design and here again, is the pre on bypassed. So this is the original signal off the microphone. Beefy. How we see things, how we like certain colors we might like set of fonts, lights. Just adjust the dancer to again. Maybe Gotham. And maybe you want to clean up the turning off. And also, let's adjust this Dr graphic side of motion design. Socialize the demotion design side, she'll say. So really drive this compressor if you want a more radio sounding voice, how during a long we have a de ESA where we can adjust the frequency. Also, the threshold Number eight signal a number eight motion. Obviously, that's quite extreme setting. So let's just reduce. This was the number eight. You wouldn't have an opinion on it. You don't have a thought on it because there was nothing for you to see. For you to be able to see something you, for you to have an opinion, something. Then we have enhancer, which is similar to a Q. As you have a low frequency enhancer motion is the number one thing the human brain sees above everything else. The number two thing the human brand sees is lighting of brightness. We also have, Ah, high frequency and having cinema. Unless you said, there's a slight little light on on the cinema screen and everything else is black. Your eyes will immediately. What? Look at that, Andi. The third thing, our faces and going along, We have a gate. Sorry on the fault. So let's just adjust. The threshold here has on a picture on a screen on. Then we'll look at that face is something that we always and also the ratio. Obviously, this is quite extreme gate setting. Let's just dial it back to bring some of the audio for again, actually recording this in quite a noisy room. So this gate is very handy because there's a sound of his computer. I can actually hear the sound of a road on this. Also output go listen to. So let's get back to the unconscious site, which is the animation on DA then I like to think that as if design and special effects were like the clothes that you wear, motion designed the actual margin part will kind of be like how to turn the lights on in the room. I thought this was the microphone were sounded like four. We went through this pre empt. You need to have the lights on in the room to kind of show you off. And that's how I think of motion design. So this is just a really handy way to add some processing to your audio before it's actually recorded. So if wants to live streams or kind of a short cut in recording audio, this mic pre amp process is very useful. Like I said, I do think you can get a better sound overall if you mix your audio in a digital audio workstation such as Logic Pro. However, this is a great alternative. So do recommend having looked at it, especially for situations we can't mix your audio. It streamed out lives such as live streaming podcasts, YouTube live that kind of think so. Thank you for watching this lecture. I hope you found useful and I'll see you in the next one
29. Thanks and Bye + Class Project: Okay, So in now at the
end of this class, thank you so much for watching
and I hope you found it useful for your class project or what needs to
actually record, edit, and process your
own audio in Audacity. I then want you to
take a screenshot of this and then write a
few sentences about what you did to edit and process
your audio and then posttests as a class project so I can
see exactly what you did. So thank you again for
watching and bye for now.
