how to un-ipod some m4a songs.

[Brian Dunn <job17and9@xxxxxxxxxxxxx>]

I'm trying to un-ipod some songs.
Does anyone know why the following command gives me an mp3 with a horid 
hiss?

#!/bin/bash
for i in *.m4a; do
       faad -o - "$i" | lame -m s - -o "${i%m4a}mp3"
done

using the faad plugin in XMMS gives me crystal clear sound on these 
songs, but stinking not so for this here command.
