Abstract
A system for generating at least one remote virtual speaker location in connection with at least a partial reflective environment (or) 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 (or) remote from the audio speakers, by emitting ultrasonic sound from at least one parametric speaker (or) associated with the audio speakers and oriented toward at least one reflective environment which is remote from the audio speakers.
