General Ideas....as always it's source dependent.....
I usually use 2 layers of compression on vocals. One that's a general squash with 4-6 db of reduction on the loud sections, and then a limiter type stage as a safety net and to lift the vocal a little. Back when I did alot of pop stuff I'd absolutely floor the compression on vocals but now I'm backing it way down...
as machinated said....quick attack, medium release, and I usually go 4:1 with about 6db of reduction or 8:1 with 4db of reduction.
I AUTOMATE vocals alot. Tails of words, the breaths up and down depending on it's emotional relavence....
EQ- This is really hard to say cause it's soooo different person to person. For me, I do some cutting on shit that bothers me (wierd honks and rings and other annoying things) and then a gentle (key word GENTLE) lift in the top end to add some air.
Hope that helps a little
