Abstract:
1. A method, comprising: receiving input signals from at least two microphone arrays each comprising at least two microphones to generate microphone signals; supplying the microphone signals to a beamformer comprising a wanted signal beamformer and a blocking beamformer, in the wanted signal beamformer, combining the microphone signals with a computer processor such that signals from a wanted direction corresponding to a first one of the microphone arrays and a given speaker are transmitted substantially without attenuation and signal components of directions other than the wanted direction are substantially attenuated; and in the blocking beamformer, substantially suppressing at least one of the microphone signals from the wanted signal direction, and transmitting with minimum distortion at least one of the microphone signals from directions other than the wanted direction.
