I need a little help on setting up compression levels for a lead vocalist (he is a really good singer, but we dont have the best equipment to say.) I just ordered a presonus firepod but its no in yet so i want be on top of things when it gets here. But ive been using just an sm57 to record him through a nady mixer. It doesnt sound bad at all, just sounds like somebody is stepping on his crotch because the vocal track sounds really shrill, and im just curious is there any compression method i could add to this to help make it a little warmer?
