Hello,

I seem to be encountering an anomaly when trying to load in sound files 
with libsndfile-1.0.12.

I was wondering if this is a Csound orchestra compiler error or an 
error in libsndfile ?

Appended is the output from Csound. The .csd example was the demix 
example Victor posted some days ago with commandline options:

-d -odac -b1024 -B16384 -+rtaudio=alsa

This is on Debian (unstable) kernel 2.6.14.

The audio file does not seem to be the issue as identical code seems to 
work just fine with libsndfile-1.0.11 on both Mac OS X 10.3.9 and 
Windows XP using this file as well as various other audio files as a 
source.

The resultant error happens no matter what audio file is selected as a 
source - the orc compiler thinks that the sr = the number of channels..

0dBFS level = 32768.0

It seems that you are trying to load a mono file into twe channels.

I would suggest that either:

  a) csound should flag this an an error

or

  b) it should convert the single channel into two channels.

Oops, missed that :-).

If you recompile libsndfile, make sure to run the test suite. Here's
what you do:

     ./configure
     make
     make check

The "make check" step runs the full test suite. If any test in
the test suite fails it will print an error message. If you 
see one of those, post it here.
