Hi Dave, just a clarification, Algazi & Duda’s system does not use binaural recordings, it approximates them using a spherical microphone array, not dissimilar to ones used in ambisonics. But instead of combining all microphones to generate the binaural directivities (as in ambisonics), it interpolates only between the two adjacent microphones that should be closest to the listener’s ears. Otherwise, it does not capture pinna cues or cues from a non-spherical/assymetrical head.
To be honest, the ambisonic recording and decoding provides a better framework for imposing individualized or non-individulized HRTFs on the recordings (it is harder to do that in their method), but you need high-orders to capture the high-frequency cues.
