I'm recording a song right now with my band, and I was wondering what effect or combination of effects could give the illusion of a large number of people singing the same part, like a crowd. Thanks in advance.
double tracking the shit out of the vocal part and then pan the tracks to seperate parts of the stereo spectrum is a good place to start
In some computer programs such as Audacity you can copy and paste tracks so you could take one track and copy and paste it into another one and then pan them. You could also do some harmony on it which gives the illusion of alot people singing. In Audacity you can for an example change the key of a track.
from experience, a little bit of delay helps
