I only ever do edits to songs and I only use Audition. I was wondering what effect or method to use to make vocals appear as “part of the music” instead of just slapped on top of the track, ifyou know what i mean. If i just do a mix paste, obviously it sounds awful and very amateurish.
I don’t know what Audition is, but it’s a matter of making a good mix.
Making different elements sound good together is pretty much the
definition of a mixing engineer’s job. There’s no tricks apart from eqing,
compressing, gating and adding reverb or delay.
That being said, it’s of course very important to have the vocals
in the same key as -for example- your bass line.
Or a related key like the dominant (5th / +7) or possibly subdominant (4th / +5) keys. You can tune the acapella and/or instrumental accordingly. DJing software like Virtual DJ can help you to detect the key and tempo and sync and retune the parts.
Here’s the circle fifths to see the dominant (clockwise) and subdominant (counterclockwise) keys.
