Abstract

See full text

A system for generating at least one remote virtual speaker location in connection with at least a partial reflective environment in combination with an audio speaker for creating multiple sound effects including a virtual sound source from the reflective environment which is perceived by a listener as an original sound source, by generating a primary direct audio output by emitting audio compression waves toward a listener, and generating a secondary indirect audio output from at least one virtual speaker remote from the audio speakers, by emitting ultrasonic sound from at least one parametric speaker associated with the audio speakers and oriented toward at least one reflective environment which is remote from the audio speakers, thereby indirectly generating sound from a reflective environment which is perceived as a virtual speaker, and synchronizing the primary audio output of the audio speakers with a secondary audio output from the at least one virtual speaker such that the listener hears a plurality of sound effects from a plurality of directions.
