Subject: SoX bug: smpl chunks deleted

I noticed that when converting stereo sample files to mono, the 'smpl'
chunks (which encode loop information used by sample players), SoX omits
the 'smpl' chunk in the output file.

For example,

sox input.wav -c 1 output.wav

sums a stereo input.wav to a mono output.wav.  However, the 'smpl' chunk in
input.wav is discarded.

I have a workaround; I wrote code to extract the smpl chunk and append it
to the output.  But it would be nice if 'smpl' chunks were supported by
default, at least for the easy cases.  (I realize it could be difficult or
impossible for many cases.)

What's the best way to file a bug report?

BTW I'm new here.  SoX RoX!
