I'm curious, I have a client who wants me to take the vocals they have in their mix and multiply them to give them more of a choir effect. (It's currently a small chorus and I need to make it a little grander).
I'm trying to think of ways to do it without destroying the mix entirely.
One idea i had was to use something like DrMS, separate the Mono/Middle and export it... then EQ it to try and isolate the vocals as best as possible, then apply some reverbs / delays and Antares Choir plugin to taste to create a full effect track, then remix that back in to the main mix-down.
Any better ideas?
