Abstract
A beamforming microphone system capable of reducing a processing load caused by calculation of directivity and flexibly setting an area where sound is picked up. A beamforming microphone system according to the present invention includes: a plurality of microphone units; a signal processing unit that processes a sound pickup signal from each microphone unit at each predetermined time; and a storage that associates, for each sound pickup area, sound pickup area information with individual-sound-pickup-area position information freely set within the sound pickup area and stores the information. The signal processing unit includes a position information identification unit that identifies sound source position information, a signal generation unit that generates the sound signal corresponding to the sound from the sound source position, and a channel assignment unit that assigns an output channel, based on the individual-sound-pickup-area position information on the individual sound pickup area to which the sound source position belongs.
