Nevermind. I think I got it. If anyone's curious I'm using mpg321 and oggenc.

mpg321 --stereo -w - filename.mp3 | oggenc -i - --resample 44100 -o filename.ogg

--stereo is to force stereo output "-w -" tells mpg321 to write a wavefile to stdout 
piped though oggenc "-i -" is input from stdin and we resample to 44.1 khz. Yay!

Anyone know of a utility to change the frequency of an audio file? I've got a bunch of 
mono mp3s and CD audio needs to be stereo/44100hz.
