<P>PROBLEM TO BE SOLVED: To provide a sound source separation and display method and a system thereof, in particular, a sound source separation and display method and a system thereof, in which the removal of a specific sound source is the objective. <P>SOLUTION: A processing result of sound source discrimination is employed in order to use only one microphone array set to separate a plurality of sound sources. Specifically, a directional signal is extracted from the processing result of the sound source discrimination, and locations which were restricted or removed by the effects of the signal are calculated and displayed. By repeatedly performing this operation, a virtual reference signal can be created in the time domain. <P>COPYRIGHT: (C)2010,JPO&INPIT |
