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.

Abstract: In a sound source display system, an omnidirectional camera captures an image of a monitoring area. A microphone array collects a voice in the monitoring area. A monitoring monitor displays the image of an imaging area captured by the omnidirectional camera. A sound pressure calculator in a directivity control device calculates a sound pressure indicating a source of a sound in the image of the imaging area using voice data of the voice collected by the microphone array. An output controller in the directivity control device compares the sound pressure and threshold values (first threshold value, second threshold value), and causes sound image information in which the sound pressure is converted into visual information according to the result of comparison, to be displayed on the monitoring monitor so as to be superimposed on the image of the imaging area.
