ABSTRACT:
A method for processing sound signal including an L side enhanced difference signal comprising a sum of a signal being removed low frequency component from L−R signal and an L+R signal, an R side enhanced difference signal comprising a sum of a signal being removed low frequency component from R−L signal and an R+L signal, an L side output signal comprising a subtraction of signals, in which said R side enhanced difference signal being delayed to remove low and high ranges and amplified by a predetermined amplifying rate for a purpose of cross cancellation talk is subtracted from said L side enhanced difference signal and an R side output signal comprising a subtraction of signals, in which said L side enhanced difference signal being delayed to remove low and high ranges and amplified by a predetermined amplifying rate for a purpose of cross cancellation talk is subtracted from said R side enhanced difference signal.
