Somewhere Apple has some prerolled high performance float to int
conversion code available for you to convert arrays. I can't remember
where it is.

PCMBlitterLib.c/.h is in one of the Core Audio examples, either in the SDK or in /Developer/Examples/(probably)Darwin/iokit/etc, IIRC.

AltiVec can beat it, but you have to arrange for the data to be aligned properly.
