Does anyone know how to process the recorded lead vocal to sound like the chorus in the following song: http://www.youtube.com/watch?v=CP5fBx8JLoQ I know this technique is very common with this type of music (especially during the chorus). My guess is a harmonizer using the same vocal notes many times over with the original vocal. The sound is very "synthesized" and almost has a vacuumed effect. I know there is a standard harmony during the chorus, but I'm talking about the sound of the lead vocal itself. I noticed it falls back deeper in the mix during the chorus too. Thanks!
