Sound source separation system, sound source position estimating system, sound source separation method and sound source separation program

摘要

Problem to be solved: to provide a technique capable of effectively utilizing characteristic sound collection results when a sound source exists at a position equal to a distance from a plurality of microphones.Solution: a collecting data acquisition section for acquiring the collected sound data collected by a plurality of microphones from a first sound source located at a first position in which the effective distance from the plurality of microphones is equal and a second sound source located in a position other than the first position are collected andBased on the sound collection dataA frequency spectrum acquisition section which acquires a frequency spectrum for two dimensions of the circumference and the time direction of the circle where the first position is centered and the effective distance is the radius isBased on the frequency spectrumThe first sound source spectrum and the spectrum of the sound output from the first sound sourceThe second sound source spectrum which is the spectrum of the sound output from the second sound sourceIsolateSource separation partA sound source separation system is provided.
