post a .wav file? Before and after your EQ? and a file w/the vox in the mix? It's impossible to say "here's how you do it" with zero information about what you're working with? There are dozens and dozens of things that could be suggested, but with no information? It's a little difficult... i.e., how are they mixed? How is the song mixed? What plugs are used? Are you doing any M/S processing, and if so where? etc. etc. etc...
It's like saying, "How do I get a girlfriend, who's hot?"
BTW? How do I do that? (and one that puts out, but is not too clingy, or demanding, or witchy? Who is younger, but not too young? Who is interested in a relationship? But not wanting to pin me down? And doesn't spend too much of my money?"
P.S., she must have a job (a good job) and be self supporting, and not depressed, or on any anti-depressants, or any other psychoactive drugs of any kind (stimulants, depressants, anti-anxiety or bi-polar drugs) and
NOT going through a crisis "of any kind"...
P.P.S., you tell me how to do this? And I'll fix your vox, "Guaranteed..." And I will pay you to do so. See? It's really not that easy..
