[linux-audio-dev] Additional chunks in WAV files with libsndfile ?

[fons adriaensen]

Hi all,

is there a recommended way to write / read additional chunks in
WAV files, using libsndfile (assuming it's possible at all - I
didn't find any hints to this in the docs) ?

What I need in particular is some way to calibrate the time 
axis - i.e. to say frame #N corresponds to t = 0, and some
other similar info, mostly sample indices.

TIA,
