[Sumover-tech] RAT on OS X

That sounds like a great project - A better OSX driver would be very
useful to alot of people. RAT is currently supports up to 32Khz on
quite number of platforms (so OSX shouldn't be a problem) - above that
it can behave slightly strangely.  The current driver was written for
OSX 10.3 but the sound support was a bit more limited in that version
of OSX - however we can only afford the resources to support it on OSX
10.4 which is better and has all the functionality to support higher
sampling rates (and more channels etc) in its CoreAudio API's:

A couple of people are working in this area though people haven't had
the time to work on it directly so far - I'm sure we can assist as
needs be - just send questions to the list.

We look forward to some developments in this area!

Thanks,

Piers.
