I just finished editing mine, I used the Envelope Editor in Audacity to level everything out, I think it worked better. It takes a bit more time, but I listened through and there's no jarring volume changes between the voice and music. I basically just played around and set it so that there's only a few spikes above the 0.5 level on the left. Seemed to work ok, I didn't have to bring the speaking parts up much, but I could bring the music down a good bit. I'll post it after Keith and Chemda finish thier show. My connection's too slow to run both at once.
