mpg321 will do this if you're after a command line tool (which also means 
you can script it!):

sudo apt-get install mpg321

Then simply:

mpg321 -w wavfile.wav mp3file.mp3

Done :) Plus it's much faster than "real-time", unlike the Xmms option which 
will only be done at normal time while you listen to the tracks.

To script a whole directory into wav's you might want to try something like 
this (untested off-the-top-of-my-head hack):

for MP3 in `ls -d *.mp3`
    WAV=`echo $MP3|sed s/\.mp3$//`
    echo "Converting $MP3 -> $WAV.wav"
    mpg321 -w $WAV.wav $MP3

This script assumes it is running in the same directory as the mp3's and 
your mp3 collection all have extensions with ".mp3" (ie lower case).  Play 
with the WAV=`....` if your filenames aren't output properly :)


Too much of everything is just enough.
