If you're going to disable the AGC on each playback deck, then consider running all mp3s through mp3Gain
http://mp3gain.sourceforge.net/But for SS2 in the final output section, I think you can get better results by using just the AGC in each deck (NOT the multiband or limiters) and make the deck AGC nice and slow, with lots of gating. I have presets for what I'm talking about, for people subscribing to get my private files.
grb, why is your stream in mono now?
