Re: Octave and sound in/out

[Ronan Scaife]

Dear all,

Torsten Marquardt has written an excellent set of mex files for
Matlab to do simultaneous sound-card multi-channel input-output
under Windows.

The code (although written for Microsoft VC++ 6) is well
documented, and could probably be easily ported to Octave.

He has made the source code available at:

Best Wishes,
