Underdetermined Sound Source Separation Using Power Spectrum Density Estimated by Combination of Directivity Gain
TLDR
A method for separating underdetermined sound sources based on a novel power spectral density (PSD) estimation is proposed that enables up to M(M-1)+1 sources to be separated when we use a microphone array of M sensors and a Wiener post-filter calculated by the estimated PSDs. Expand
