Skimming the follow-up posts, it appears Rob got you started down the right path. Your producer either misspoke or was trying to give you an equivalent concept.

If you recorded a bunch of audio vocal tracks not sung to a click track, or less likely, a bunch of tracks sung badly in time to a click track, now you have a serious problem trying to align these tracks in your DAW. Is that what is happening here? If so, each DAW may have a way to do what Cakewalk calls 'audio snap' (or at least that's what they called it in SONAR; don't know about now). It is also possible to micro-manage each track, snipping them into pieces (called clips) and manually moving them left or right to fit, and/or tempo stretching a clip to fit. This is painstaking work, but sometimes it's the only answer. Your audio engineer will have good skills to do this most efficiently.

KGU 2, could you confirm if I'm on the right track here?
