Abstract
Head-tracking comprises remixing audio input data or channels to discrete device audio reproduction channels, to alter the audio input data or channels' perceived location in 3D space, in a manner compensating for relative head movement (compensatory manner), based upon provided head location data. Phase (delay) of the desired audio input data or channels is altered to shift the perceived sonic image location in 3D space, in a compensatory manner that correlates to a desired location relative to a designated device reference point. Amplitude of the desired audio input data or channels is altered to shift a perceived sonic image location in 3D space, in a compensatory manner that correlates to the desired location relative to the designated device reference point. Altering phase (delay) is performed using a constant delay function for each of the desired audio input data or channels that is independently varied based on current head location data.
