before you actually begin editing
audio in Adobe Audition let's get used to the play back and view controls as well as
is what we're seeing on the screen
right now we're seeing as I actually added three different audio files to
this project
right now I'm in waveform editing mode which means it can allow me to edit one
waveform at a time, so currently I'm
editing the moonlight serenade it goes from 0 seconds to about 3
minutes and 16 seconds you can see the actual
official duration of the audio file in the duration column with the files panel
so this is basically showing the minute you open it up
the minute you get this going so that you
can start editing it, its gonna show you the entire waveform from start to finish
if I double click this Glenn Miller documentary
narration I can double click it and this is only a 48 second file but it's still
showing you
the beginning all the way to the ending even though it significantly shorter
then the moonlight serenade file, so
when you actually editing a waveform
the one thing you need to really pay attention to is the play head
so the play head is this red line has a little golden pick
sort of thing at the top and this is gonna allow you to move backward and
forward through the audio file
it's also going to show you where it's playing currently
its gonna allow you to select different things what not so
if I move this forward and backward you're gonna come here scrambled sound
because
going to try to show you in real time what it sounded like so
if I move it backward and if I move it forward
so it's kinda trying to show you sometimes you can tell when it's
scrambling through and tell were errors are and what not
so that's basically how you move the play head around now if you click
in here and drag it's different than clicking up here and dragging if I click
up here and drag
it's actually just moving through the audio file
if I click in here and drag its actually selecting a portion of it
so be really careful with that because if you select a portion of it
and then accidentally hit the delete key on your keyboard
there's the potential that you won't actually even realize that you just
deleted the big
portion of your audio file, so in general
move your play head using this pick up here
and if you want to select, then you click in here click and drag to make a
selection
now sometimes I want to see
specific chuck's like if I really is editing
this first peace of it and he made a mistake with one the words or there's
kinda really big
inhale or exhale it's really hard to edit it right now because
I'm seeing the entire length the audio file
so what I need to do is come down here to the zoom control
we have a zoom in and zoom out for the amplitude that's kinda the spikes that
you're seeing here
and then we also have this zoom in time and the zoom out
in time, now when you hover over it you can see the keyboard shortcuts with zoom
in is gonna be
equal key and is the amount is going to be the minus key
so lets just hit this a couple times and its gonna allow us to zoom in
to time so if I wanna edit this chunk right here it's a lot easier now because
everything's kind of stretched out as you can see it starts at 0 seconds but now
it only goes to 12.5
the rest of the audio file is there there but I'm just seeing
this particular 12 seconds of time for this audio file
if I wanna see different spots of that audio file
I can drag this slider up here so I can go all the way from zero
to the end which is at 48 seconds the little red line
that you see here you can also see
in the slider control so that you can go back to where your play head
is playing now increase in the amplitude is weird because
you can increase the amplitude by actually
changing the sound because in amplitude is showing you spikes where it gets
really loud
versus really quiet so anytime you see a tall spike that means it gets loud at
that point increasing the amplitude is actually gonna change the volume level
but what if we just want to see bigger spikes
we don't want to get louder we just want to see the spikes in
kinda more drastic so that it is easier to edit
in will last three can use these controls to zoom in or zoom out to the
amplitude so
let's go ahead and zoom in and see how it's making those spikes bigger
it doesn't change the actual audio level at all it just kinda stretches them
out so that it
easier to end it and we can see kind in the gaps between
so these are personal preference you choose how you wanna watch
or a look at this actual audiophile and again you have all these different
keyboard shortcuts that
you should get used to you I'm because you're gonna be doing this all the time
now the playback control you can use these regular controls and here you can
stop it
play it you can use the pause button but again
as you can see every time we hover over them it'll show you what the keyboard
shortcuts are because most people when they're editing audio
they use the shortcuts way more frequently than they actually press a button
a couple these to note the red record button
don't hit that if you're in here if you don't intend to record
because if you select something here in action accidentally hit that
its gonna try to record over this portion audio
now another cool feature this is I can highlight this little
and section right here and I can hit the loop
and notice when I create a selection the plea had goes the very beginning
then when I can do is they can hit the spacebar and is gonna play
only once in that current selection and if I hit the loop button
its gonna keep playing and keep playing and keep playing its let's can help me
when it when I get into tricky spot with editing so let's go ahead and play it
glenn miller's glenn miller's glenn miller's glenn miller's
so that could be really helpful when you're kinda
in a spot where you're really trying to figure out where you should edit where
should cut where you should silence
what not, so I'll take that loop feature off, now
what I do is I actually don't use these controls at all
I use the keyboard shortcuts of I wanna play I'll hit the spacebar
if I wanna stop it on hit the spacebar again so I'll hit
spacebar to start represents a contradiction and space for it to stop
now
in addition something that you don't see here is you can use the J, K and L
keys on your keyboard to move forward backward
and to pause so the J key is gonna move things backward
so to the left the K key is going to pause it
and the L is gonna move it forward so if I had the J key once
its gonna play it backwards and then if I hit the K key it's gonna pause it, so lets
see that,
markets are as beer, and then k to stop it
so if I hit the L key, its gonna move it forward in real time
History of Jazz represents a contradiction and the K key is gonna pause it now watch what
happens
when I hit the L key twice the first time it's gonna move in real time
in the second time its gonna make it go a lot faster so every time you hit the
J or the L key
multiple times it's gonna go faster and faster and faster so
I'll hit the L key once though many jazz enthusiasts disapprove his
discipline, okay one more time, jazz enthusiast
think
and K to pause, so those are the basic playback controls
and view controls that you need to be aware of and use to when you're
working in Adobe Audition
