Topic: Pacthing snippet from one channel to the other

[Duncan]

Hi

So I've got a recording with a little bit of noise on one of the channels, clicks and things, and what I want to do is patch in the other channel to remove them. Only about 1 second snippets or less

Do you guys have a simple way of doing this?
I'm on a Mac so if it's a particular bit of software that has a good workflow for doing this it would have to be for Mac

I can do it but it's a long winded way in Peak that I can't use that any more due to a change of laptop

I might just go duel mono with the good channel but would still be interested in other options

No specific help from me but I would be wary of just patching in a second or two from the other channel - I worry that the sudden jump to mono could be quite jarring.

If I was going down this route, I'd consider a fairly long crossfade into each patch.

But have you tried a de-clicking filter first?

I'd be happy to do it with a longer cross fade but I don't know how to do that

It's not just clicks, a few times it's rubbing where I've got my mics in my collar and I've moved my head and caught the mic with my stubble

It's an Andy Mckee gig so it's a lot more noticeable that my normal fare of heavy rock

I'm not a Mac person, but I imagine that most audio editors would allow you to convert the stereo file into 'dual mono' so that each channel can be edited separately.

Then I would cut out, say, 5 seconds of the offending channel and highlight and copy the corresponding section of the good channel but with a good 3 or 4 extra  seconds (or more) at each end.

Then paste the good section over the gap in the good channel. Most programs will automatically perform the crossfades at the areas of overlap, so you'll just need to make sure the clips are synced up - zoom in and match up peaks on the waveforms.

There may well be a more straightforward way of doing this but I think this is what I would do as a first attempt.

I've done this once and the simplest way for me was:

1. Open in Wavelab (or any other DAW  / wave editor) and highlight the offending section of music across BOTH the good and the bad channel
2. Right click (or other selection method) and select the good channel only, whilst keeping both channels still highlighted
3. Copy that section of the good channel and paste onto the previously highlighted bad channel, if the paste is applied at the start of the highlighted section it will be perfectly synched

If it's only a few seconds long noise (it was for me) the difference will not be noticeable and I did not apply any fades etc, it was loud music though.

Clever.

You do need to watch for phase offset issues when doing this.  You may be time aligned in absolute terms but if the channels are not in phase then the part you copied from one to the other will be some milliseconds off and (depending on the software) may not join cleanly.  When patching I always look for a suitable place for the beginning and ends (if you just do the part with noise it may jump in at the middle of something which is more likely to be noticeable).  Zero crossings are the best spots for any splice/patch operations. 

I'd agree an editor with a click and pop function that can be applied only to the areas in question is the best starting point.  Another approach is just to zoom real tight on the noises in question and decrease their output level significantly.  That can fade them into the background and be less distracting than a mono patch.
