Description
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.
