Abstract
An acoustic processing apparatus includes a sound source localization unit configured to estimate a direction of a sound source from an acoustic signal of a plurality of channels, a sound source separation unit configured to perform separation into a sound-source-specific acoustic signal representing a component of the sound source from the acoustic signal of the plurality of channels, and a sound source identification unit configured to determine a type of sound source on the basis of the direction of the sound source estimated by the sound source localization unit using model data representing a relationship between the direction of the sound source and the type of sound source, for the sound-source-specific acoustic signal.
