More questions! Can't let you coast on your last few days!
What percentage of the tracks you get have fundamental flaws? What kind of flaws do you see - distortion on the vocal, inverted phase/polarity on the drums? meters hitting the red in ProTools, bad edits?
Not much, I'd say less than 10%. Our biggest problem is too many tracks, 4 kicks, 4 snares, MS gtrs, MS acs, Too many tracks and not enough voices(although, i'm getting a new rig soon) Bad edits on vocals ins't uncommon. Files imported from logic or nuendo lose their cross fades sometimes if they aren't consolidated.
