Source image estimation device, source image estimation method and source image estimation program

摘要

A good source image can be estimated.The source image estimating device 10 calculates a separation matrix for separating each sound source signal from a mixed signal mixed with a plurality of sound source signals collected by a plurality of recording terminals.The source image estimating device 10 calculates the source image on each of the recording terminals of the separation signal corresponding to each sound source signal using the calculated separation matrix.The source image estimation device 10 then applies a linear filter to the calculated source image and outputs a source image in the linear filter output.Diagram
