Audio processing system and method

摘要

A system for receiving and processing audio signals includes a handheld audio processing device and an audio receiver unit. The handheld audio processing device has a plurality of microphones located on the handheld audio processing device that define a surface and at least a pair of intersecting axes on the surface where each of the axes is defined by at least two microphones. The handheld audio processing device also has a processing subsystem configured to receive audio signals generated by the plurality of microphones and to spatially filter the audio signals and a transmitter configured to transmit the spatially filtered audio signals. The audio receiver unit is located remote from the handheld audio processing device and configured to receive the spatially filtered audio signals transmitted by the handheld audio transmitter.
