VIRTUAL REALITY SOUND FOR ADVANCED MULTI-MEDIA APPLICATIONS
First Claim
1. A method of generating virtual reality audio for a participant of a virtual reality simulations the method comprising:
- computing an independent audio profile representing participant-independent propagation of sound from a virtual source to each of one or more virtual objects in the virtual reality simulation;
determining a location and an orientation of a head of the participant;
computing a dependent audio profile representing participant-dependent propagation of the sound from the one or more virtual objects to the head of the participant based on the determined location and orientation of the head;
combining said dependent audio profile with said independent audio profile to determine a total audio profile for said virtual source; and
filtering said virtual source based on said total audio profile to generate said virtual reality audio associated with said virtual source at the head of the participant.

Abstract
The method and apparatus described herein generates realistic audio for a virtual reality simulation based on the position (location and orientation) of a participant'"'"'s head. The audio may be generated based on independent and dependent audio profiles. The independent audio profile represents the participant-independent propagation of sound from a virtual source to each of one or more virtual objects in the simulation. The dependent audio profile represents the propagation of the sound from each of the one or more virtual objects to the head or ears of the participant based on a position of the participant'"'"'s head or ears. An audio processor generates the desired audio signal at the head of the participant by combining the dependent and independent audio profiles to determine a total audio profile for the virtual source, and filtering an audio wave corresponding to the virtual source based on the total audio profile.
