Video and audio conferencing system with spatial audio
First Claim
1. A system, comprising:
- a first plurality of microphones;
a second plurality of microphones for producing an audio signal of a participant; and
a computing system coupled to the first and second plurality of microphones, wherein the computing system is configured to;
beamform a response of the first plurality of microphones to determine directional information for the audio signal relative to the first plurality of microphones; and
transmit the audio signal from the second plurality of microphones and directional information.

Abstract
In some embodiments, spatially realistic audio may be provided for a conference call. Voices from participants on the left side of a display, in a conference call, may be directed through audio on the left side of the display at the other conferencing system in the conference call (similarly for voices from the center and right side of the display). In some embodiments, two speakers may be used in the system to create synthesized stereo sound at a location specified by directional information received as side information along with the existing audio channel. The location may be determined by using beamforming with integrated microphones on a camera or speakerphone. In some embodiments, the audio signal and directional information may be sent in the form of a left audio channel and a right audio channel.
