Anyone have any tips on recording a large vocal "crowd shout"? For example, the tail of the choruses on Atreyu's "Falling Down" from the album Lead Saild Paper Anchor, or the beginning of "Lay Your Hands On Me" by Bon Jovi? I am trying to make it sound like a very unison, very tight "yell" and would like to avoid recording twenty five tracks of the same line. (It is difficult to get it tight enough using this approach, and occupies quite a chunk of disc space). Just curious if there may be another approach that the pros use to create this effect. Any advise is much appreciated!! Thanks!!
