editing left and right channels separately

[noneedforaname-1uaHUE]

Hi all,

I have a question about editing either channel in a single audio track. I know how to separate the channels, and how to edit them, but I have noticed that the master track doesnt change after editing. Am I missing a step?

Thanks

I was with you until you mentioned a master track. Are you editing in Multitrack view?

[noneedforaname-1uaHUE]

forgive any possible confusion. What I mean is that the main track that I imported into Audition doesnt change when I edit the left or right channel. Does that make sense?

You haven't answered my question! Are you editing in Multitrack or Waveform view? They behave completely differently!

Okay - what exactly are you trying to edit? If you try to remove time from a single channel, you'll fail completely - all that will happen is that you'll end up silencing that portion in the other channel. And no changes are permanent until you re-save the original file.

Mainly I am trying to edit audio levels on either the left or right channel. When I make the left channel louder in the split view, it doesnt change in the original track

Are you talking about using the the preview editor? It works fine for doing that here. If you click on the blue L or R on the RHS of the waveform you can edit a single channel, and if you highlight a section to reduce the volume on, the change is immediately reflected in the non-preview (lower) view.

So here's what I mean. I insert an audio file. Then go to Edit -> Extract channels to mono files. I then edit those mono files, but the original file is unchanged. How do I turn those edited mono files into one stereo file?

Why would the original change? You've created two new mono files from the existing stereo one, and edited them. You haven't done a thing to the original file at all!

If you want to alter the levels in one channel of your original file, then do as I suggested above (although you don't need the preview editor to do it); use the L and R buttons to disable temporarily the channel you don't want to edit, select the section you want to alter the level of, and use the HUD volume control. If that's not visible, then go to View>Show HUD and enable it. This will make a volume alteration to one of the channels, which will become permanent when you save the file.

To get back to a stereo file from your two mono ones involves copying one of them, and converting the sample type of the other one to stereo. You then select the 'empty' channel using the L and R buttons appropriately, and paste the first file into the space you've created for it. Basically it's a right palaver, with the possibility of getting the channels mixed up - and as I've shown, for this sort of operation, quite unnecessary.
