>Subject: Creating MP3s

Language study at the University of Chicago is moving (fairly abruptly) 
into digital delivery. I have captured audio from tapes as .wav files 
(40 kHz, 16- or 24-bit). I want to convert these to mp3s files, but I 
find that iTunes (which I am using right now) gives me three pre-set 
options and then I can customize as I choose. Can anyone tell me what 
perceptible differences they have noticed among these various options? 
Good (128 kbps) and Higher (192) (both mono and 48 kHz) sound basically 
the same to me, with a 13 MB difference in size for the same material. 
What would 320 kbps get me? (Is there anyone out there doing phonetic 
analysis of language audio?)
