On this topic did anyone else see the NHK broadcast a few months back
about a digital version of binaural recording that alters the phase
frequency response of the high end of close miked material to extend the
stereo sound stage vertically. The trick works by tweaking the frequency
phase relationship to match what the ear expects from a wave incident at
a given angle. It just sounded odd on loudspeakers.

Was this some kind of dummy head recording or some kind of ambisonics
(Gerzon) WXYZ recording ?
