Assume there are 4 microphones in a linear array form like this : # # # #
they are named x1,x2,x3,x4 . someone speaks and these microphones recieve the speech each with some delay corresponding to their distance. We need to find the time delay between microphones. These all are simulating in Matlab , in order to find delay we need to crosscrolate the signals in Matlab. Does any body know of the apreciate function ?
