ears are your best judge, but dont go by the crappy speakers that came with the computer. this is where a good set of headphones come into play.

there is a way to see the sound. cd wave shows how the sound "looks" and allows you to determine things like volume, if it clips, etc. after some time, you'll be able to look
at your "soundscape" and figure out when the snare, tom gets hit, if its an ambient passage, crowd yelling like mad, whistles, etc. make sure you do this with wav files

however, it does not tell you how it sounds. ears are the best judge.
