1. You can use lame to encode the WAVs to MP3s. Once wav file created using cdparanoia you can use lame to encode the file wav to an MP3:

   lame myfile.wav myfile.mp3

   lame also supports bitrate option for example to use 256 kilobytes bitrate you can use:

   lame -b 256 myfile.wav myfile.mp3

   Read man page of lame for all supported options.

2. to convert all mp3 files at once, do:
   for i in *.mp3; do mpg123 -v -w "${i%mp3}wav" "$i"; done

   1. nice

3. To convert all mp3 files, accounting for spaces in names and correcting the “filename.mp3.wav” naming, try:

   IFS=$'n' ; for i in $(ls |grep mp3$) ; do echo $i ; mpg123 -w `basename $i .mp3`.wav $i ; done

   1. You did not set back IFS:
      add last command :
      IFS=$’ nt’
