- Hello, I'm Mike Russell from MusicRadioCreative.com.
In this video, we'll look
at the Adobe Audition preferences menu.
This is a mini series where I'm covering everything
in Adobe Audition preferences.
And today, it's audio hardware and channel mapping.
(bright upbeat music)
Let's hop to it.
And remember, before I get started,
if you wanna never miss a video again, first of all,
let more people know these videos are good
by liking this one, then click the subscribe button
and get every video I ever release notified straight
to you by dinging that bell.
Okay, here we are in Adobe Audition
and I'm gonna bring up the preferences menu.
Again, multiple ways on PC, it's Edit, Preferences.
On Mac is the Adobe Audition menu, Preferences
or you can hit Control or Command + comma
and bring it straight up.
And we're gonna look at channel mapping and hardware.
Audio channel mapping, and audio hardware.
Now, it's best to start with the audio hardware
before you go into the channel mapping.
And on a PC, it's a little more complicated,
'cause you've got all kinds of different device classes.
You got ASIO, you got MME, you got WASAPI.
Generally, I stick with ASIO.
I like to work
with audio interfaces that are ASIO compatible.
And as you'll see here, I've got all my devices available
to me that I have plugged into my computer.
I use a Soundcraft USB mixer called
the Soundcraft Signature 12 MTK.
It's really, really good.
Down here, you can see
I've also got Focusrite interfaces plugged into
my computer as well that I can also select.
If I hit Settings here,
it will take me to my Soundcraft settings
and it will allow me to tweak them a little bit further.
If I wanted to change certain settings
with my Soundcraft desk using
the Soundcraft software itself.
But of course, if you're working on Mac,
you don't need to do all of that.
Most of the drivers are installed automatically
for you on Mac.
And to be frank, on Mac, setting up audio hardware
is a lot easier.
You can change the I/O buffer size.
I have got mine locked to 512,
but you'll often find
this can range to a large number, to a small number.
Really, the ideal situation
for I/O buffer size is to go as small as you can.
But when you start getting it too small,
your computer can't keep up very well and you get clicking
and popping in the recordings that you make.
So, if you get that error
if you get clicks, and pops, and crackles,
and distortion, and any kind of weirdness
when you are recording audio
in Audition, increase this number.
You wanna make it the smallest it can be
without affecting the audio.
So, this might be a case of trial and improvement,
where you just go through increasing that number slowly
until you find a number that works for you.
For me, I can increase and decrease that number
in the Soundcraft settings and I've found 512 works for me.
Sample rate is the sample rate you wanna be working
in with your audio files.
Most audio that we work with as producers, podcast editors
will be 44,100.
So you can leave this as 44,100.
If you are working with video files mainly, 48,000
is the one you want to go for.
And here, you've got a tick box Attempt to Force Hardware
to Document Sample Rate
if you really wanna make sure some hardware,
for some reason, tries to switch a sample rate
or insert incorrectly.
If you really wanna make sure you are always working
in 44,100, tick this box
and it takes everything outta control
and Audition tries to force those settings
to your audio interface.
Okay?
So that's that.
You can also Use the Machine Specific Device Defaults,
so whatever you've set up in your control panel on Windows
or in your settings on Mac will be generally applied
there to your audio hardware.
So, that's audio hardware in a nutshell.
Make sure you get it right,
otherwise you won't be able to play or hear any audio.
Now, the reason I went through this one first
even though it's below channel mapping,
is you can't set up audio channel mapping
until you've set up the hardware device
you're gonna be used to play back and record audio.
So, let's switch over to Audio Channel Mapping
and you'll see here, you've got the Default Stereo Input
and the Output, which are both my Soundcraft mixer.
Now, here for me, as the input
I can say which channels
I want to record from my Soundcraft.
Channel 13 and 14 are my stereo mix.
And, then I've got loads of other channels
here that I can record.
They're all different tracks and inputs on my mixer.
Let me give you an example.
If I go into Waveform and I start a brand new audio file,
and we'll call this Audio Input like that,
and I start recording hello, this is me.
This is a stereo mix of me recording.
Okay?
That is my stereo mix.
Back into Adobe Audition,
and I dunno why I just minimized it,
let's go back into it.
There it is.
I hit Control + M instead of Control + comma.
There we go.
Okay, here we are back into Adobe Audition.
I could change this Analog One, which is my raw microphone.
And when I do that and click Okay,
you'll usually have to start a brand new audio file
and say Audio Input One like that.
Hello, this is me with my raw microphone.
So, you'll see how this has recorded
my stereo mix, hello, this is me.
Okay.
And then over here,
this has recorded my raw unprocessed microphone.
Hello, this is me.
Much quieter, this is pre-fader essentially.
Hello, this is me.
And this is post-fader.
Hello, this is me.
You can hear the difference.
But for me, I'm gonna go back to Audio Channel Mapping
and make sure I'm always recording my process stereo mix,
as that is what I want for my voiceovers.
And then over here for Output,
I've got stereo channel seven and eight on my mixer.
For you, this might be channel one and two,
but for me it's seven and eight.
And if you're working in surround sound,
you can actually assign this to different speakers depending
on what kind of audio interface you've got.
But generally, for most users, you'll want to select
this as left and right channels
and it'll be a stereo feedback.
And for most of you,
if you're not using a multi-track mixing desk,
this will generally be Analog One
or Output One, sorry, and Output Two.
And, that will get your audio out.
So generally, for most people, audio hardware
will just be a case of selecting it, making sure buffer size
and sample rate are correct,
and then selecting the input as channels one and two,
and selecting the output as channels one and two.
Don't worry about any of the rest of this,
unless you're working in 5.1 surround or ambisonic audio.
You can just stick with the basics there.
And, that will get you up and running
with your audio hardware
and your audio channels all working.
This can be such a crucial part of setting
up Adobe Audition, 'cause if you get it wrong,
you won't hear any audio
or be able to record any audio.
Remember, if you wanna learn the full processes
that work inside Adobe Audition, go and check
out my courses.
They're open for enrollment right now
at mrc.fm/learn.
That's mrc.fm/learn.
