Moving Sound Source Separation by Extension of Microphone Width

Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, a moving sound source separation method by two microphones using multiple weighted sum circuit is studied. The sound source separation performance strongly relates to the sound source tracking performance because the separation method using directivity is based on sound direction estimated. The tracking method using sequential updating histogram is improving the tracking performance by an extension of microphone width. However false peaks appear in directivity pattern, and it degrades the separation performance. In the studied method, the spatial aliasing is avoided by introducing a virtual microphone.
