does anyone know how to change them?
To less i mean, obviously you can't improve the sound quality of an mp3!
Ive got a load of mp3's in 320kbps quality, which are just taking up too much space on my limited iRiver!
I need to cut them down to 160/192 kbps to make room for more stuff
(and no - i can't just re-rip them, they're not from my cd's)
