3D Audio Unit + Sample Conversion + Performance Hit

The 3D Audio Mixer gives a pretty major performance hit -- I'm still
going to use it since it's a bit better than my quicky routines, but
the hit is noticable (about 5-10% at lower fps).

Next up: I do pitch by changing how I feed the data in the input. I
want to try out the conversion module and see how speed is on that.

I'm pretty sure I hook up kAudioUnitID_PolyphaseSRC audio unit, but how
do I change how it works? Do I setup the stream format on both the
input and output?
