lIn
Ambisonics, the directive microphones IRs are simply matter of changing the gain (and perhaps the polarity) of a Dirac’s delta function
lIn the
binaural case, instead, a complex stereo IR is required for any direction-of-arrival
lA large data
base of stereo binaural IRs (HRTF) is available from MIT-Medialab
lA proper
routine has been developed for interpolating
the required IR starting from the knowledge
of the direction of arrival of each discrete
early reflection.
