It would not surpise me that Octave's audio processing functions do
not work correctly on modern systems.  They were written about a
decade ago to work with simple audio formats using external programs
that may no longer be commonly used, and they have not been modified
much since then.

I have not looked at what is available in octave-forge.  Perhaps there
is something better there?

In any case, if people want something better, I think the route to
take is to write the code and contribute it for everyone's benefit.

Thanks,
