I'm mixing an acapella choir in pro tools with 20 tracks. There are a lot of times when one singer or another isn't singing the same rhythm as others.
I know there is a plugin that can sync the rhythm in different tracks together. Anyone know it?
Re: @coaxmw 's answer
Both VocAlign & Re-Voice are good tools, but I'd be careful of 'over-aligning' a choir - I once did it [with VocAlign] & ended up with 80 tracks that sounded like 6 people & had to start over to preserve the 'size' of the end result.
A choir really doesn't align that precisely, even when they're 'good'.
Melodyne might be a better bet, though more manual to implement, you have more flexibility over how much to push each syllable/word/phrase.
Sometimes it might be better to just align the more noticeable aspects, P's, T's, S's etc & allow other segments a little more freedom.
One trick is to group the tracks & give them all an identical tiny fade out at the ends of phrases, based on the tracks closest to your intended phrasing. The artificial endings imposed on subordinate tracks will really not be noticed [caveat for phrases ending in a P or T, of course]
All this, of course, depends on just how close the original takes were in the first place - if they were miles out from each other, then some manual cut/timestretch/paste might be the quickest start-point.
You may try a simple sidechain gate/expander setup. I used this to control dubs several times with success.
This way you "sync" the start and ending of all the sources with just one or two, and you won't loose the wide image choiry image that arise from not having perfectly aligned phrases etc.
