Patent ID: 7667728

Claim:
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; beamform a response of the second plurality of microphones to determine directional information for the audio signal relative to the second plurality of microphones; cross correlate the beamformed response of the first plurality of microphones and the second plurality of microphones to determine final directional information for the audio signal, wherein the final directional information indicates a left side or a right side of the second plurality of microphones; and transmit the audio signal from the second plurality of microphones based on the final directional information, wherein the computing system is configured to transmit the audio signal by transmitting a left audio channel and a right audio channel, wherein the left audio channel comprises audio from at least one beam on the left side of the second plurality of microphones and the right audio channel comprises audio from at least one beam on the right side of the second plurality of microphones.
