Well,
I went back into this thread and it seems to be also a problemk I am
experiencing... I'm using the HAL through Java to access the recording
(and playback) facilities. I want to perform resampling on the fly and
get crackling sound, apparently, between each chunk of audio that go
throught the AC.
Is that the same problem, and do I have to use the AudioUnits as well?
If so... What is the AC for?

The AudioConverter is not designed to change sample-rate on the fly like
this. The AUVarispeed AudioUnit should be perfectly adapted to this
application by tweaking the "rate" parameter on the fly.
OK, I'll try that. Is it using FFT or is it doing simple resampling? I
need the latter, that's why I tried the AUConverter. To me,
AUVarispeed sounded more like timestretching than resampling.
I suppose there's no other documentation than the WWDC presentation
Bill mentioned?
