SOUND SOURCE SEPARATING APPARATUS, SOUND SOURCE SEPARATING PROGRAM, SOUND PICKUP APPARATUS, AND SOUND PICKUP PROGRAM

摘要

There is provided a sound source separating apparatus including a bidirectionality forming unit configured to form a bidirectionality by use of a sound signal picked up by two microphones which are located to be horizontal with respect to the target direction, among three microphones disposed at vertexes of an isosceles right triangle, a unidirectionality forming unit configured to form a unidirectionality by use of a sound signal picked up by two microphones which are located in a same direction as the target direction, among the three microphones, and a target sound extracting unit configured to extract a target sound by performing a spectral subtraction of all outputs from the bidirectionality forming unit and the unidirectionality forming unit from a signal.
