Sound Separating Device, Sound Separating Method, Sound Separating Program, and Computer-Readable Recording Medium

摘要

A sound separating apparatus includes a converting unit that respectively converts signals of two channels into frequency domains by a time unit, the signals representing sounds from sound sources. The apparatus also includes a localization-information calculating unit that calculates localization information regarding the frequency domains and a cluster analyzing unit that classifies the localization information into clusters and respectively calculates central values of the clusters. Finally, the apparatus further includes a separating unit that inversely converts, into a time domain, a value that is based on the central value and the localization information, and separates a sound from a given sound source included in the sound sources.
