Document Type and Number:
WIPO Patent Application WO/2021/193093
Kind Code:
A1
Abstract:
Provided is a signal processing device comprising: a reference signal generation unit to which a mixed sound signal picked up by microphones disposed at different positions and obtained by mixing a target sound and sounds other than the target sound is inputted, and which generates a reference signal corresponding to the target sound on the basis of the mixed sound signal; and a sound source extraction unit which extracts, from the mixed sound signal, a signal which is similar to the reference signal and in which the target sound is further enhanced.
