    m4a to mp3
      ffmpeg -i filename.m4a -acodec libmp3lame -ab 320k filename.mp3
      for f in *.m4a; do avconv -i "$f" -b 256k "${f%.m4a}.mp3"; done
      (ls|grep m4a) | while read f ; do (avconv -i "$f" -b 320k -c:a libmp3lame "${f%.m4a}".mp3); done

    rencode mp3
      for f in *.mp3; do lame --mp3input --preset cbr 320 -s 44.1 --bitwidth 16 "$f" "$f"; done

    WAV to MP3
      for f in *.wav; do avconv -i "$f" -b 320k -c:a libmp3lame "${f%.wav}".mp3; done

    
example usage

  this will take an mp3 file, reencode it to ogg and mp3 
  streams at 128kbs and stream them to an icecast server. 
  cat myfile.mp3 | 
  fan "madplay -b 16 -R 44100 -S -o raw:- - 
       | oggenc -b 128 -r -B 16 -C 2 -R 44100 --raw-endianness 0 - 
       | streamer 0 host port pass mount" 
      "lame --mp3input --preset cbr 128 -s 44.1 --bitwidth 16 - - 
       | streamer 1 host port pass mount"
