Package: octave2.9-forge
Version: 2006.07.09+dfsg1-4
Severity: normal

The following small script:

clear
x = randn(1, 65536);
x = x / max(abs(x));
wavwrite('noise.wav', x)

seems unfailingly to write a WAV file which claims to have 32767
channels. It works fine with octave2.1-forge (with the parameters to
wavwrite reordered appropriately for the older API).

According to the documentation:

octave2.9:1> help wavwrite
 -- Function File:  wavwrite(FILENAME, Y)
     Write Y to the canonical RIFF/WAVE sound file FILENAME. A sample
     rate of 8000 Hz and 16-bit samples are assumed. Each column of the
     data represents a separate channel.

your input matrix must be organized in columns.  The following code should
do what you want:

x = randn(65536, 1);
wavwrite('noise.wav', x)

I am therefore closing this bug report.
