Abstract:
An audio processing device includes a sound source localization unit that determines respective directions of sound sources from audio signals of a plurality of channels, a setting information selection unit that selects a setting information from a setting information storage unit that stores setting information including transfer functions of directions in advance for each acoustic environment, and a sound source separation unit that separates the audio signals of the plurality of channels into respective sound-source-specific signals of sound sources by applying a separation matrix based on transfer functions included in the setting information selected by the setting information selection unit.

Claim (Index 4):
The audio processing device according to  claim 1 , wherein the setting information selection unit is configured to record history information indicating the selected setting information, to count a frequency of selection of each setting information on the basis of the history information, and to select the setting information from the setting information storage unit on the basis of the counted frequency.
