Title:
SOUND SOURCE SEPARATION DEVICE, SOUND SOURCE SEPARATION METHOD, PROGRAM AND RECORDING MEDIUM
Document Type and Number:
Japanese Patent JP2017187687
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a sound source separation device that suppresses unwanted sound coming around from other sound sources and separates sound of a main sound source.SOLUTION: The sound source separation device includes: a gain calculation unit 130 for calculating a gain G(ω) from a power spectrum P(ω) of a frequency domain signal X(ω) and a power spectrum P(ω) of a frequency domain signal X(ω) (k being an integer of 1 or more and N or less, except m); and a gain multiplication unit 140 for generating a post-correction frequency domain signal Y(ω) as X(ω) G(ω) from the gain G(ω) and the frequency domain signal X(ω).SELECTED DRAWING: Figure 1
