1. Audacity intro vid 1: In this Udacity
Quick Guide course, you will learn how
to make your audio better and that too quickly. Okay, we'll start right from downloading and
installing the Odacity, setting up the audio
recording editing. We'll also learn few
effects and at last, we'll see how to
save the project and export the audio if
you're interested. What are you waiting for?
Let's see you inside.
2. 2 Record edit and effects basics: Let's get started by downloading
and installing Audacity. To do that, you need
any web browser. So I have opened my
Google Chrome here, and I'm searching for Udacity. Here we go, Download Udacity. I'll just simply click on it. Now as I'm using Windows, I'm downloading it for Windows. You may also download from Mac, Linux as per your requirement. So I'll just simply
download for Windows. Now the download has started and it has completed
successfully. I'll just simply click on this. Click on Okay. I'm satisfied with the language English,
so I'll click on Okay. Click on Next. Next.
Next I'll say yes. Click Next Install. Now finally launch
Udacity is ticked. When I click on Finish, it'll automatically
open Audacity. So here we go. We
have successfully downloaded and
installed Udacity. And now we don't need
this web browser. So I'll just close it now. I'll maximize it now
to record an audio, the first thing I would do is I will just check my audio set up. So I'll just simply
click on audio setup here and I'll see what
is my playback device. My speakers are
selected, that's good. Now what I'll do is I'll check
the recording device here, my mixer is selected, so that's totally fine. Again. Now again, I'll see
the recording channel. I want to record it in mono, single track, if you want stereo track, you
can do that as well. So I'll just go for mono. Okay? Then to record,
to start recording, I need to simply click on
this Record button with the shortcut for this is R. And if you want to
record it in a new track, then the shortcut is Shift plus R. You can see here itself, it's showing you, I'll just simply click on this
and it starts recording. Now in case you want to pause your recording
in between not stop, pause, you can simply click
on this pause and it pauses. Okay. If I click on that, it'll continue
from there itself. It'll start recording
from there itself. No, you want to
stop the recording. Then you can simply click on this Stop button and it stops. Okay? Now, if you want
to record from here, just give a click here and
then click on Record again. It starts again, but
what if I want to start in a new track as
you have already seen? It's shift to place
R. Let me press Shift and R here you can see it started recording from new track to start in the new track. You might be thinking
that, why did the recording start from
here and not from here? Because I was clicking
this position, you can see that it
started from there. Now in case you want
to just play and see, you can click from wherever
you want to start playing. And you can click on
this Play button. If you want to pause,
you can pause it. It'll stay wherever
you paused it again. If you want to play from
the place where you paused, you can just click on the
pause and it charge back. Okay? Instead, if you click
on Stop while playing, it goes back to the initial
position where it started. Okay, See I'll just
play Show you start recording now in case.
And now I'm giving Stop. It won't stop here. Instead
it will come back here. Okay, so if you stop, it gets back to the
initial position. So I'm just playing it again. So how can we do it
with the shortcut? So if you want to
pause it, you may press from a keyboard. And to play it back
from there itself, you can press P again
in between, okay? And if you want to
stop, it's Spacebar. And if you want to
start it's Space Bar. Okay. To stop and start,
you can use Space Bar. So I'll just remove these tracks now by pressing
this close button. And one more thing that
you need to look at is, here is the recording meter and here is the playback
meter, Okay? When I record, and now you can
see whatever I'm speaking, it's showing me the level. Okay? And if I stop it and if I play now, okay,
you can see the level. Whatever I'm speaking,
it's showing me the level. Okay. Now let's remove this and let's record
something properly. Okay? So I'll just close this. Hello, I'm Minder and
you're learning audacity. I would request you to make a practice that whenever
you start recording, please be silent for a couple of seconds so that it can
record the room noise. Okay? And once you're done, please wait for a while Okay, so that it can record
the room noise. So now let's see how to
remove the noise if there is. Okay, so you need to select
the portion where you did not speak and just go to
the Effects menu now. Noise Removal and Repair. And then click on
Noise Reduction. Okay? And you need to click
on the Get noise profile. Okay, So what it'll do is the portion that you selected
where you were silent, it'll just take the
noise profile from that. We need to remove noise
from entire area. So what we'll do is
we'll select everything. You can select the whole track by just double clicking it. Okay. Or else you may also
press controller here. I have selected the ten track, now effect noise
removal and repair, and again, noise reduction. Now just simply click on. Okay. And please abso
here, here and here. If I click okay, see the knot. Something like that. For
let's once play and check it. Hello, I'm mind and
you're learning Day. Okay. If you want, you can remove the
unnecessary portion. That's up to you. I'll
just remove it simply. Hello, I'm miner and
your learning Udacity. Now what I'll do is I need
to increase the volume. It's very low, right? So what I can do is
I can just select the track again by
double clicking on it. I'll go to the effects
volumen compression, and I'll click on Normalize. Okay, Normalize, I'll just
make it up to minus three DB. Okay? For instance, you can
also go with minus one D B because I want to show you some more effects which
will increase the volume. So I'll just keep it up to minus three D B here. And
click on Apply. And now you can see
it has increased. But you can see
another thing that is they are not equal, right? Means some part of it is loud
and some part of it is not. I mean, they are
not equal in level. So let's play and see once. Hello? I'm him in there and
your learning day, okay? To level them up, we use
something called compressor. Okay? I'll just select
the track effect, okay? And then I'll go to
volume compression and click on Compressor. I'll not go in depth because
this is a quick guide. So you can go with
defaults and it does a good job if it
is not on default, it's moved here or there. What you can do is
you can simply go on presets and settings
factory presets, defaults, and it'll
make it default, okay? So the only thing
I'll do is I'll just reduce the
attack time, okay? And then click on Apply. Now you can see the
compressor has done its job to show you this was
before and this is after. Okay, to show you
before and after, what I have done
is I just pressed control to undo and
again control y to redo. Now let's see. Hello, I'm miner and your
learning audacity. So I have not covered
compressor in detail. We have gone with the default, so don't worry about it. As of now, you can see there are a lot of peaks here, right? So another way to
remove those is go to Effects Volume and Compression
and make a limiter. Okay, what I'll do is here you can see
Limit to D, B, okay. I'll make it as per my
requirements and click on Apply. And now you can see
there is limit, okay? Now if you wish to, you can again normalize. If you normalize, this time
I'll go with minus two V. Now, hello, I'm Minder. And your learning audacity. Okay, so far so good. Now to get some base
boost or Treble boost, what we'll do is
we'll just simply double click to select it. We'll go to Effect, and then we'll go here
for EQ and Filter. So we'll go for filter Q. Now by default it
doesn't come like that. You can just click on Flatten if it's not
available like that. Okay, So what I'll do is
I'll just click here. Okay? Raise this bar up. What this does is it
base your treble. Okay? So let's apply and see
Now, let's listen to it. Hello, I'm in your
learning audacity, Okay? That's the difference.
Now I'll select it again. I'll go to filter. Okay? And then I'll show
you by another method, graphic Q. This time
we'll go for that. You by default have
presets, okay? No need to go with
these things directly. Go here, Presets and Settings. You can click on
Factory presets, you can click on Base Boost. If you want to
increase the boost, what it does is it
increases the base part. If I click on Apply, and now let's see on Hello, I'm mind learning Udacity now. You can clearly see
the difference. Okay. You can see your audio
has already been improved. Hello, I'm miner and
your learning Udacity. If you want to boost
the travel again, you may do that, but I
don't think it's essential. So let's see, Once first I'll just double
click to select it. I'll go to effect Q filters, graphic EQ preset and
settings factory preset. And then I'll do a travel boost. Okay. If I click on. Okay. And now see Hello, I'm Minder and your
learning Udacity. Here you can see some portion is just going beyond the limits. So what we can do is
we can add limit here, effect volumen
compression limit. Okay? It's already up
to minus three DB. You can experiment
with it. I'll just apply this and see, here we go. Hello, I'm miner and
your learning udacity, You can do it as per your taste. Let's see next. I'll
just remove it. I'll record something. Hello, this is he. Now, here you can see that
some portion of it is too loud and some portion
of it is not okay for that. I already showed
you how to do that. But let's see, another method. If you want to selectively
increase volume, I'll just select that portion. I can go to Effects volume
compression and amplify. You can increase
the volume here. Okay. So you can see
that if I go too far, the preview and Apply
button gets faded out. If you want them to come back, you need to click
on Hello clipping. But I wouldn't recommend
that that would go too far. So what I'll do
is I'll just come to the place where they
don't get fade out. Click on Apply and you
can see it has increased. Okay, Let's hear it again. This is, you need to keep in mind that I have not done
the noise reduction at all. Okay. What I'll do is I'll
just select them now and just click on
Volume Compression. And I'll just go to
Normalize and click Apply. Now you can see it's with the
noise Hello, This is Amend. I forgot to do the
noise reduction, but I would always recommend
doing the noise reduction. First, select the noise portion, go to Effects, then go to
the noise remote and repair. Click on noise reduction,
get the noise. Then select the entire track. Okay, Then go to Effects Noise, remo pair noise
reduction, and click on. Okay, that does the job. Hello, this is this part. You can see that it's not
that clear because it was recorded very low and
we increased the volume. It's still not that good. This is okay. I'll just delete this
and record a new one. Hello, this is Men and
your learning. Udacity. I'll just remove the noise
select noise noise reduction. Get noise profile. I'll select
the entire track effect. Noise remo noise reduction. Okay. Now the noise
has been reduced. I'll just get it normalized. Volume compression,
normal apply. Now I'll show you how to
change the pitch off it. Okay. I'll just double click it to
select the entire effect. And then pitch in tempo
and click on Change Pitch. What change pitch does is it changes the pitch
off your voice. Okay? If you drag
it towards left, your voice sounds thicker. If you drag it towards right, your voice sounds
like a chipmunk. Okay, let's see. First with the left side. I'll just move to
the left side a bit and let's see the preview. Hello, this is Ember
and your learning dack. I'll just do it a bit more. Preview. Okay, if I just get back to zero here now you can see
it's almost zero. And now if I go towards, right, Hello, this is Amanda, and you're learning Audacity. Okay. I'll just
do it a bit more, ma, so you get an idea
how to change the voice. Okay. If you simply click
on Apply, it'll be applied. I don't want to do that, so
I'll just move it up. Okay. Next I'll show you how to change the speed and the difference between the speed
and tempo, okay? So if I click on Effect, this is selected.
Keep that in mind. Click on Effect, go
to pitch and tempo, and then select
the change speed. Okay? If I want to
make it slower, I'll pull it towards the left. If I want to make it faster, I'll pull it towards the right. Okay, so first let's go
with the slower one. So I just pull it back.
Let's take a preview. Hello, this is member
and you learning mode. Now you can see that it's
just slowing down my voice, but it's also changing
the pitch off it. Okay, so this is the problem
with the change speed. If I just pull it forward
to make it faster, let's see that preview. Okay, It's making it faster, but also changing my
voice like a chipmunk. If you don't want
to change the pitch off your audio while
changing the speed, then you need to
use the temper one. Okay, select this, go to
Effect Pitch and Tempo, and click on Change
Tempo Instead, if I just slow it down by
going towards the left one, I'll just hit the preview
button here, Learning Day. So now we can see that it
has not changed my pitch. Instead it just slowed
down the audio track. If I just move it towards
the right and now let's see, hello, this is learning day. It has changed the
speed of my audio but did not change the pitch. That is changed tempo, so now let's see reverse first, I'll remove the unnecessary
part from here and here. Okay, And I'll
select this track. I'll go to Effects Special. And here you can see
something called reverse. If I click on reverse now
it'll be interesting. Let's listen to it. I have
never learned this language. Hope you might have also
not heard it right. It's simply reversing
your audio, which sounds like this song. A. I'll just undo it by
pressing control, and now. Hello, this is Amanda and
your learning Udacity. Okay. Right. Now, in case you want to repeat it
multiple number of times, what you can do is
you can simply go to effect special repeat. For example, I want to repeat
it two times more, okay? So I'll click on Apply. And you can see it
repeats two more times. So I'll just remove them in case you want to cut from here. Okay, You want to
make a cut from here. What I'll do is I'll
put the cuss at that point and you can press
control to split it up. When you press control, it
gets splitted into two parts. I'll just delete the
entire track and let's record another track
to show you the next thing. In some movies you
might have seen, wherever the person is saying some bad words,
they just beep it up. Right? Let's see how
they beep it up. Hello, I'm hem, I
want you to beep this word right now
here I'm cursing, Okay. So this should be beep. I'll just simply normalize
it without just doing the noise reduction thing because that would
save some time. Okay. I'll just normalize it. Apply Hello. I'm ma, I want you to
be wherever I'm saying. Beep. I want to beep it up. Okay. I just selected
that portion. Okay. Now, in case you want
to select it precisely. Okay. It's going
somewhere like this. If you want to
zoom it, if you're using mouse and
you're on Windows, hold the control button
from your keyboard. Okay? Place the
cursor wherever you want to zoom and scroll it up. Okay? This will zoom it up in case you
don't have a mouse. What you can do is the numbers which are on the top,
not on the side. You can press control
one to zoom and control three to zoom out in case you don't want
to do it like this. Here is the shortcut, okay? Zoom in control one, you can see zoom
out control three. You may click these as well. Can now adjust it like
this. One more thing. If you want to make your track
fit to the width control, you can press and if you want to fit it to the
height control shift F, okay, I wouldn't do that. If there are multiple tracks, you can do control shift
to fit it to the height. Okay. This thing
is selected now. Now I want to just beep it up. I'll go to Generate Here, and then here there is
something called tone. Okay. I'll click on that tone. Let's, let's see. I want you to this
word for example, this cursing is in
actual cursing, I'll just select that
thing, generate tone. So let's see here. Okay, so this should
be beeped. That's it. Now along with this, let's learn if you want to
silence something. Okay, so I selected this part. I don't want to delete it, I can just select it and press Delete Key from the keyboard. It will remove it, but I
don't want to remove it. I want that place, but it
should not sound anything. I'll just click on
Generate and Silence. Click on Generate. Now, see
it has got silence there. Hello? I'm in the.
Okay. Okay. Now I'll remove this and I'll just show you how to import
an audio inside. Okay, let's minimize this. On the desktop, you
can see there is an audio which I have taken
from my Youtube studio, Okay? So this is the track, okay? So I'll just get it inside. So there are a couple of
ways of getting it in. One, you can just
simply drag it inside. Okay, that's a method, one else you can click on File, Import Audio, and you
can select your desktop. And then select it, okay. In both ways, you
can get it inside. Once done, okay. It's in studio track, so it's visible like double. So don't worry about it
may reduce it as well. Okay, to get it full, I already told you that
you can just click control left and it
takes the full width. Now if I want to record
something in new track, you already know that
I can press Shift R. Hello. This is Amend. And you're watching
Audacity tutorial right now, Right with me. Let's see how to do auto duck. I have just recorded audio. Okay. What I'll do is
I'll just play Hello. This is Edata tutorial
with me for example, if I want this audio
after some time, after some time, music starts. Okay, So I'll just move it here. Let's hello, this
is amending now. Audio is not properly
audible, right? So what we'll do is we'll just
simply select this track. Instead, I would
like to just zoom it here by pressing hold control
and scrolling my mouse. Well, or else you can do it from here as well.
I already told you. Okay, I have zoom
this portion here. Now what I'll do
is I'll just first amplify my voice. Okay? You need to do noise
reduction and everything, but I'll just simply
normalize it as of now, volume
compression normalize. This time I'll go up to
minus one, D, B maybe. Okay, amplify. Now you can see this peak is
taking away all the room. What I'll do is
I'll just click on Effect limiter, volume
compression limiter. I'll just limit it up again. I'll normalize. Okay? You may do it more as per
your requirements, but right now I'll
just play it directly. Hello, this is an and
you're watching still. This is not clear
what you will use. You will use something
called Auto Duck. You need to select
that music track, double click it from Volant Compression,
click on Autodock. What is Autoche volume is it detects that and lowers the music volume
at that portion. Okay, if it goes suddenly
that doesn't look nice. What it does is it
fades and fades out. Okay? Before the, before
it ducks the volume. How much fade in? Fade out is required, Should
be selected from here. Okay? It's 0.45 seconds
and 0.38 seconds. Let's make it both 0.45 Why not? Okay. Now, how much the portion should you can select as per your requirement or else you can go with the
defaults as well. Let's apply and see, you should see the
change here, okay? Here and here, okay, apply. And you can see,
let's play and see, hello, this is amend and you're watching
Audacity tutorial. Okay, now let's do
another experiment. What I'll do is I'll just split the track
here, make a move. Split the track
here. Control make a move. Okay,
Something like this. And now let's
select this effect, Volume compression, auto duck. And this time I'll just make
it direct. Almost direct. Okay, So ten I guess. Let's apply and see. You can see wherever there is audio it has detected
and gone down. Wherever there is not, it brings the volume up
again. Let's explain. Hello, this is Evander Audacity tutorial right now. Okay, so I hope you understood
this Autodock feature. You might also have a doubt that can I do it
manually or not. So you can definitely
do it manually as well. So I'll just hit the
control head here. Okay. Now if I want
to do it manually, what I'll do is I'll just select this envelope tool here. Okay? The shortcut is F two,
so I'll click on it. I click here, once again. Here. Okay, till here. It needs to get hold of it. And from here I'll
drop it down again. I'll hold the second
point and make it down. Okay. I'm doing it in
reverse. Sorry for that. I need to hold it from here
and I'll take it down. Same here. I'll take it down
and increase from here. Now you can see this
is done manually using Envelope tool Hello. This is Vender. Okay. You
can do it manually as well. I'll just do it by
pressing control. I'll remove this audio
from the bottom. Now, I'll just get back
to the selection tool. Okay. And now I'll show you how to do the fade
in, fade out effect. For example, I'm
taking a Music okay, and I'm just cutting
it from certain point. For example, let's do
it practically, okay? So I'll just hit control F, so that the track fits
the entire width, okay? And I'll just select a
random portion and I'll make a split by using
control shortcut, okay? And I'll select
the starting part and remove it by
pressing delete key. And now I'm getting
it at the beginning. Okay, So I'll just
get it like this. Now if I play, it's
starting suddenly, right? So what I need to do is, and
also I need it till here, I'll make a cut again. Here. Control. I'll
split it up. Delete it. And now let's see
the ending as well. It's almost good, but if you want to make it
much more smoother, you need to use
fade in. Fade out. I'll select certain
portion here, go to Effect, and
then go to fading. And click on fade in. Now you can see it's
starting slowly. Okay? Something like that. The same thing if you want
to do with the ending. You'll select that portion
and go to effect fading. And click on fade out. Okay? Now in case, imagine you have
multiple tracks here. Okay? I'll just copy this. You can just simply select
click control D as well. It will give you more tracks. Okay, I already told you if you want to
adjust the height, I mean zoom in. Zoom in to fit. So you
can press Control Shift. And now you can
see it has zoomed properly so that everything
fits in almost okay. If there are too many
tracks, it wouldn't do that. It won't fit all at once, okay? It'll do the best. For example, you're working on multiple
tracks and you want to rename them or make a
color coding out of it. You can do that as
well. Here on the name, I'll just click on this
arrow and click on Name. And you can name
it, for example, one. Okay, Track one. You can name it something else. So that you can
name it like this. Two what we say, Music or something like that. You can rename it if you want to differentiate
them visually, you can do it via colors. I'll just select this wave color and I'll make it instrument
two, for example. Whatever belongs
to that category, I'll just turn them red. Okay? For example, I want
to change the color of it, wave color instrument
three, okay? This is for example, instrument for something like that you
can do the color coding. Okay. This will help you
understand it easily. I'll just delete them all. Once again, import the
audio track, okay? And I will record one voice
over here, for example. I'll just record my voice again. So I'll just press shift R. Hello. This is band and
you're learning audacity. Okay? So in case I want to listen only to this track
and not to this track, there are a couple of ways I can either mute it up and listen. Hello, this is okay. Else what I can do is if
there's so many tracks, I can't go muting each
and every track, right? So I can just simply
click on this solo here, so it'll mute
everything except this. Okay, Now if Hello, this is band you're
learn audacity. Okay. So in case you're using your
earphones or headphones, something like that, you
will feel this effect. Which I'm going to say now, sometimes you hear some music like playing in your left
ear ones and right ear on. What you can do is if I want this to be heard
in my right ear, I'll just pull this towards R. If this should be
heard in your left ear, I'll just pull
this towards left. I'm panning it. Okay,
so let's hear it once. Hello, this is band and
you're learning audacity. Okay. You can make efforts
like this as well. I'll just reset it. I'll just solo it once. Okay, And remove the
unnecessary portion. I'll just normalize it. Hello, this is band and
you're learning Audacity. Make sure you know that I have not done the noise
reduction part, so there could be
some disturbance. What I'll do is I'll just make
a copy of this track now, control D, and here we go. I'll select this track. I could directly apply
the next effort, which I'm going to show
on this track itself, but I would like to
do it separately. Okay. So that you can
have control on it. I would just remove
the solo from it. Okay. I will mute
the track for now. Now what I'll do is I'll
just select this track. Okay. And go to effect
reverb delay here, I'll use reverb is a room
resound thing, okay? For example, there
are several presets. If I go to factory reset
and if I select bathroom, let's hear a preview of it. Hello, this is band and you're learning audacity. So
something like that. Okay, so I'll just
go to the defaults and you can play with
the room size and all, so you get different variations. But now what I want to do is I don't want
to hear my vocal. I most probably want to hear the only sound effect that
the riva bits making. What I'll do is Vet only. But before that, let me
give you a preview of it. Hello, this is Hebda. You're learning audacity, okay? Now if I click on Only, okay. So this is the difference. So I'll just click on Apply. Now what happens is I can
just the volume from here, how much effect do I need? Okay, So I'll just play it once. Hello, this is Bender. Okay, now this is
also playing in. This is also playing, so we're
getting both the effects. What I'll do is I'll just reduce the intensity of it.
I'll mute it up. Let's play it. And I'll
remove the mute in between. Hello, this is Bender, and you're learning audacity. Okay. You can see the
difference for you to observe. I'll just make it a bit more. I'll mute it up. Play it again. Hello, this is band and
you're learning audacity, so you can see the difference. Okay, Now let's mute
the music as well. Okay? And I would like
to manually take it down a bit. Let's hear it now. Hello, this is band and
you're learning audacity. Okay. I have already
showed you how to increase the base and
treble thing also. You can try that as well. So I'll just select
this. Effects first, I'll go with the compressor. Apply. Okay, hello,
this is Hebdo is. I'll just simply go to effects filter curve and apply this. Hello, this is Hedda. Now if I want to boost the base, what I'll do is
I'll just simply go to filters, graphic resets. And then I'll just simply select base boost from here. Apply. Let's see, hello, this is Bender and you're
learning audacity. Okay, there's a lot
to learn in Audacity. This is just a quick
guide on how to record your vocals
and some basics. Okay, let's see how to save the project and how
to export the audio. Okay, There's a
difference between them. So I'll just simply click
on File, Save Project. Say Project As, or Save
Project, Whatever you can do. Okay. I'll click on okay. And now I'll select the desktop. And I'll name it, for example, my project, okay? And I'll save it up. Now if I close this, I can reopen my project from here and start
working on it again. Okay? You save the project
for the future references, for the future purpose
to edit it back. But if you want to
make it as an audio, what you will do is you can
