To get you started:

for file in /opt/*.wav; do
	oggenc -q 4 $file && rm $file
done
# forget about compressing the files because they're already compressed
mv *.ogg /opt/mp3backups


Note that I use oggenc here, because I'm not familiar with the command 
to convert to mp3, although I imagine ffmpeg would do it.  If you find
you need to specify an output file name, you could do it like this:

$(basename $file wav)ogg

That would remove the 'wav' extension from $file and replace it with an
'ogg' extension.

You might want to specify a working directory for the script to run in.
Maybe start it off with:

cd /tmp

Others here might have an opinion on that.
