Check out the most recent PhantomAudioDriver; it has optimized Altivec
routines for doing this. Very thoughtful of Apple - I was able to just
drop them into my driver.

Instead, you should use the blitters in the AudioConverter.
how fast is the AudioConverter compared to sample/32768?
The AudioConverter blitters use Altivec, are fully optimized, and
take advantage of a few neat math tricks so they're a ton faster.
Jeff,
Where can I get more details on these optimizations. I'm thinking about
putting them to use in CoreAudio drivers (clipOutputSamples() and
convertInputSamples()).
Thanks.
Devendra.
