-------------------------------------+-------------------------------------
 when using ffmpeg for splitting to mono files
 (for example, to get only the left channel:
 ffmpeg -i test.wav -af "pan=mono|c0=c0" testmono.wav
 )
 the resulting wav file ignores any 'smpl' chunk.
 (which can contain loop information)
 I'll add a test.wav file containing a loop in the 'smpl' chunk.
