I'm wondering if anyone knows of an MP3 encoding software that will allow you to encode MP3s in mono and/or at lower sampling rates than 44.1 khz? I have "Siren" from Soundforge, but it automatically assumes you're file is stereo/44k. Basically, I'd like to take advantage of the smaller file sizes afforded by mono/22k (1/4 the size), but "Siren" treats my mono/22k .wav files as if they were stereo/44k. Any suggestions?
