Wouldn't you want to record sound into a memory buffer then pick the
samples out that you wanted????, eg if its coming in at 8khz, and you
want 800 samples / sec, just pick up every 10th or something?????
I would imagine there is code out there to do the sampling, tho. Maybe
the SDK for winamp would be a good place to start - I think they have
the output plugins there....
