Abstract
An audio processing system, includes: an audio collector that collects audio in a non-directivity state using audio collection elements; an operator receives an input of one or more designation directions for audio emphasis for switching from the non-directivity state to a directivity state; an emphasis processor that generates audio data in the directivity state obtained by performing an emphasis process on the audio data in the designation direction from the audio collector using audio data collected by the audio collector according to the input of the designation direction; a volume adjustor that adjusts volume of the audio data in a directivity state; and an audio output that outputs the audio in a non-directivity state collected by the audio collector or the audio in a directivity state after the volume has been adjusted by the volume adjustor.
