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 2):
The audio processing device according to  claim 1 , wherein at least one of a shape, a size, and a wall surface reflectance of a space in which sound sources are installed differs for each of the acoustic environments.
