Reducing Musical Noise by a Fine-shift Overlap-add Method Applied to Source Separation Using a Time-frequency Mask
Shoko Araki, Shoji Makino, Hiroshi Sawada, Ryo Mukai · 2006
Musical noise is a typical problem with blind source separation using a time-frequency mask. We report that a fine-shift and overlap-add method reduces the musical noise without degrading the separation performance. The effectiveness was confirmed by results of a listening test undertaken in a room with a reverberation time of RT/sub 60/=130 ms.
