I have not really tested all functions in the audio package. I wrote my
audio functions since I needed a duplex (simultaneous play and record)
function for a paper I wrote to JASA last year. Then it was also relatively
easy to write separate play and record functions as well.

Not really sure. My functions is for ALSA only, that is, Linux only.

Not right now. It contains oct-files only:
ainfo.oct aplay.oct aplayrec.oct arecord.oct atrecord.oct
It is, however, not very difficult to add mex-interfaces since most of the
code is the same. However, for Matlab one can use the DAQ-toolbox for this
(I think).

Well I can add mex-interfaces (a couple of hours work). In the long run it
would be nice to have something which is platform independent. I am also
thinking of writing functions for the (real-time, low latency) audio server
jack:
http://jackaudio.org
which would make it really easy to connect to various hardware etc.
