Title:
SOUND SOURCE SEPARATION PROGRAM, SOUND SOURCE SEPARATION METHOD, AND SOUND SOURCE SEPARATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/172524
Kind Code:
A1
Abstract:
This sound source separation program causes a computer to acquire an acoustic signal, convert the acquired acoustic signal from a time domain to a frequency domain, and perform sound source separation on the acoustic signal converted to the frequency domain by iteratively minimizing an objective function including the quadratic form of a separation vector and the determinant of a separation matrix by performing an update based on an elementary row operation on the separation matrix.
