You can use mpg123 and sox to convert an mp3 to a wav file. And there is
for instances bladenc to convert it back to mp3. But think of it twice.
Changing the volume of a song can actually destroy the musical value of
the piece. And also, remember that mp3 as well es jpeg are lossy
compressions. If you uncompress and recompress, you will loose more
and more information until lowering quality well audibly.
