At this stage, one has to wonder just how much need there really is for
matching HRTF's. I'm not so convinced these dys as I once was, at least if
headtracking is properly implemented, the few "fixed" parameters are
matched (like inter-ear distances) and there are good visual cues as there
are in modern VR systems.
