摘要
PROBLEM TO BE SOLVED: To obtain a two-output signal of a high quality storing sound space information of an objective sound.;SOLUTION: A sound source separation emphasizing system has: receiving parts 111, 112 for tape-recording an acoustic signal generating from a plurality of sound sources at different two points; a filtering part 120 for forming a differential signal between receiving signals XR, XL at the different points so as not to contain a signal of an objective sound source after inputting the receiving signals XL, XR from the receiving parts 111, 112 to process the signal; a mask filter estimating part 130 for receiving an output signal of the filtering part 120 and the signals XL, XR from the receiving parts 111, 112 to estimate a time frequency filter coefficient as emphasizing the objective sound source; and a mask filter 140 for multiplying the signals XL, XR from the receiving parts by a signal G from the mask filter estimating part 130, thereby reducing an objective external sound to emphasize an objective sound holding spacial sound information.;COPYRIGHT: (C)2010,JPO&INPIT
