ABSTRACT:
A sound is picked up using a plurality of microphones that are arranged so that respective directivity axes of the microphones differ from each other or so that they function as a plurality of microphones having directivities in different directions by performing a calculation on sound signals output from the plurality of microphones. Rotation of the plurality of microphones is detected, and the sound signals output from the plurality of microphones are processed according to the detected rotation so that a change in orientation of each of the microphones is canceled. The processed output sound signals are output to a reproduction side.
