The AudioConverter blitters use Altivec, are fully optimized, and take
advantage of a few neat math tricks so they're a ton faster.
Hmmm, many applications/plugins of course need such tricks on a single
sample basis. For instance when there are dependencies or to generate a
wavetable index from a fractional counter etc.
Wouldn't it be nice to publish a small tutorial with ultra-optimized
example code and tricks for common problems? I.e.:
sin-cos approximation (getting both values at once)
pow( 2, x )
(float) int
(int) float
