Have you actually used CoreAudio or done any measurements? I think that Paul is absolutely correct to fall in love with the best performing audio API available on any platform (which is also very easy to use). I would suggest that anyone who doubts that callback based APIs offer significant advantages use CoreAudio, ASIO, etc. before taking too strong a position. These platforms offer performance equal to or better than ALSA while making it much more likely that the average programmer can take advantage of that performance by providing a greatly simplified interface.
