Residual Noise Removal in of Sound Source Separation Signal by Spectral Replacement
Taiga Saito, Kenji Suyama (Tokyo Denki Univ.) CAS2023-122 CS2023-115
Abstract (in Japanese) (See Japanese page) 
(in English) Although sound source separation method based on a multiplication of multiple weighted sum circuits has high suppression performance, a residual noise remains in the time sections where the suppression is insufficient. The sound quality can be improved by removing the residual noise in the post-processing stage, but the output signal has no spatial information because of delayed sum processing. Therefore, a method without spatial signal processing is required. In this study, a method to improve sound quality by replacing spectrum in silent section is studied.
