You can write a simple script:

#!/bin/sh

for i in `find . -name "*.mpr"` ; do
  mpg123 <options> $i `basename $i .mp3`.1.mp3
  ...
done

But this will break if there are spaces in the file names. A reall
straight forward solution could be then writing the filenames into a
file and use an emacs macro to explicitly construct the commands...
