Systems and methods are disclosed for a sound reproduction apparatus configured for receiving signals representative of the output of a plurality of microphones positioned to sample a sound field at points representing possible locations of a listener's left and right ears when positioned in said sound field at the location of the microphones, receiving a location of at least one sound source relative to said plurality of microphones, receiving orientation data of the listener's head, and calculating a binaural output using the sound source location, microphone output signals and orientation data. The binaural output includes the full-bandwidth of the microphone output signals.

Motion tracked binaural sound conversion of legacy recordings

A new approach to capturing and reproducing either live or recorded three-dimensional sound is described. Called MTB for 'Motion-Tracked Binaural,' the method employs several microphones, a head tracker, and special signal-processing procedures to combine the signals picked up by the microphones. MTB achieves a high degree of realism by effectively placing the listener's ears in the space where the sounds are occurring, moving the virtual ears in synchrony with the listener's head motions. MTB also provides a universal format for recording spatial sound.
