I'd suggest reading:
http://interface.cipic.ucdavis.edu/PAPERS/Brown1997(Efficient3dHRTFModels).pdf
It's quite short and to the point, and shows another take on what
to do for 3-D when you're very cycle-constrained. I implemented
this as sfront's implementation for Structure Audio's spatialize()
command, and was quite happy with it. The paper above is short
and to the point, a more theoretical (and longer) version is:
