One channel ripple delete (ripple left of right chans but not both).

[Zoe7traveller]

Heya - I have a stereo file where I'm wanting to a ripple delete on only one channel (either the left or the right), but I can't seem to do so.  When I attempt to delete a selection of one channel, it doesn't ripple that side.  Rather, it just creates a big blank silent spot.  Is there an easy way of doing this?

Just in case my question if confusing, I created a quick video which might help clarify my issue.

Thanks so much!!

IMHO Audition is doing this correctly. There is no way that you would normally want to remove time and upset the syncing of one channel within a stereo or multichannel audio file. That is why in the Waveform view (which works in the destructive edit mode) when you use Delete it deletes the audio ie. silences it, but it doesn't and shouldn't remove time.

If you wish to do destructive edits separately to the two channels of stereo file the proper way to do it is to split the stereo file into two mono ones from the Edit menu 'Extract Channels to Mono Files'.

But may I ask why you need to do such a time/sync destructive edit to a stereo file?

I'm afraid that Audition won't do this - even though on one level, ryclark notwithstanding, it's strictly logical as an operation goes, I suppose; as it is, it appears to delete a section of the other channel even though it's deselected, and that shouldn't happen. Hmm...

But let me try and explain why: There's a major difference between Goldwave and Audition, and that is that as you've noticed, Audition has a multitrack view. And because of that, any sort of operation that you'd think you might want to carry out like that has effectively been shunted off to that view. It makes sense, too - if we take your example, what you'd do is go to Edit>Extract Channels to Mono Files, dump them straight into a multitrack session, and then you could slide one against the other easily, whilst monitoring the effect, making it much easier to line the channels up where you want them. Make a time selection, export it and you're done.

Now you may say 'but I want to do this in Waveform view'. And that's fine - put in a feature request. But I can tell you now that the only logical reason for implementing it is that strictly speaking, Audition isn't doing the thing it's indicating that it will - it's supposed to be leaving the deselected channel alone and it isn't. But in principle, doing this sort of operation in that view isn't the way Audition is intended to be used, simply because it is, at heart, a multitrack editor.

There is another snag too. You have to bear in mind also that you're only looking at this in stereo, and Audition supports multi-channel files, not just stereo ones, which Goldwave is restricted to. Whilst I'm not saying that it's impossible to implement this, I suspect that it might not be quite as simple as you'd possibly expect...
