i was just using my edirol r-09 in an interview situation, just me and another person. sadly, due to placement of the recorder, my voice shows up MUCH more loudly than the other voice, by about 2:1. our voices are quite different, mine is higher, his is lower and more raspy, and i'm wondering if there isn't some tweak i can do with audacity to lower my voice down to an acceptable level. possible? thanks!
