 Replying to [comment:1 Cigaes]:
 > FFmpeg includes some metadata in WAVE files that other software rarely
 use, your comparison may be detecting just that. You need to extract to
 raw PCM to be sure.

 Ok thanks for the info, but in this case output from ffmpeg and shorten
 still doesn't match:

 ffmpeg -i test.shn -f s16le ffmpeg.pcm

 shorten -x test.shn shorten.wav
 ffmpeg -i shorten.wav -f s16le shorten_ff.pcm
