Hi Steve
Brian Willoughby wonderfully covered the question.
I was trying to be brief in the original post, because this topic skates close
to off-topic for the CoreAudio list.
For this kind of topic, music-dsp is an excellent mailing list (and archive of
code examples)...

One's optimizing strategy will depend on details of the target processor, and
how much time you can spend.
On PC, I use a collection of FPU ASM specialized format converter tight loops,
which are not rocket science, but took a couple of days work.
If faster PC performance was necessary, perhaps write the loops in Vector ASM,
which would take more work.
So far have only needed to do simple CoreMIDI on OSX, but if I ever need to do
CoreAudio, as long as the CoreAudio converters give acceptable performance,
would not want to spend a week rolling my own ASM converters.
