Doh!

for i in *.mp3; do
  lame --decode $i temp.wav
  lame -b 64 temp.wav $i-64.mp3
  rm -f temp.wav
done

You will end up with some files called filename.mp3-64.mp3, so you can fix
that with rename:

rename .mp3-64.mp3 -64.mp3 *mp3-64.mp3

Which will replace all filenames.mp3-63.mp3 with filenames-64.mp3
