Converting mp3 to wav

Hello

I have been using this script to convert my mp3's to wav so I burn my own
cd's.
#!/bin/bash
# mp32wav
mpg123 -b 10000 -s "$1" | sox -t raw -r 44100 -s -w -c2 - "$2"

Its great to use when there is only a couple of files. Its tedious when you
have alot of files.
I would like to convert a whole directory of mp3's to wav's. Is there a way
to automate the script to so this?
