Abstract:
A method for improved virtual localization of sound comprises making a sound at an origin point, recording the sound with two or more recording devices at, two or more different distances from the origin point, generate a head-related transfer function (HRTF) for each of signals received from the two or more recording devices at the two or more different distances from the origin point, convolving a waveform with a localized HRTF generated using at least one of the HRTFs, and drive a speaker with the convolved waveform.

Claim (Index 15):
(currently amendedl) A system for creation of multiple Head-related Transfer Functions comprising:\n a first recording device placed a first distance from an origin point; a second recording device placed a second distance from the origin point; each of the first and second recording devices comprising:\n two or more microphones separated by a horizontal distance between ears on an average human head and a head analog comprised of a material chosen to simulate a density of a human head; \n a processor coupled to the first and second head and ears analog; a memory; instructions embodied on the memory that when executed cause the processor to carry out the method comprising:\n a) recording a sound with the first and the second recording device; \n b) generating a head-related transfer function (HRTF) for each of signal received from the first and the second recording device at the first and the second distance from the origin point respectively; \n c) convolving an input waveform with a localized HRTF generated using at least one of the HRTFs to generate a convolved waveform, wherein convolving an input waveform with a localized HRTF further includes choosing a first HRTF that was generated with a first recording device from the two or more recording devices, wherein the first recording device is nearest to a chosen point from the origin point; \n d) driving a speaker with the convolved waveform.
