Vocals - moderate attack, slow release, moderate compression (4 to 1)
Kick - moderate fast attack, quick release, solid compression (10 to 1)
Just starting points. The setting on the compressor really depend on how hot the signal going into is.
Also, are you trying to control dynamic range (i.e. smooth out volume), or trying to change the envelop of the sound so that the initial attack of the sound is strong but the rest is minimized?
