Title: Crosstalk canceler and its method
Inventor: KASAI JOJI
IPC: H04S1/00
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a crosstalk canceler by which an undesirable sound in a listening sense can be reduced. SOLUTION: A left output of a feedback loop (an output of a 1st sum processing 12) is given to a 1st low pass filter 20. An output of the 1st low pass filter 20 is summed to a right output of the feedback loop (an output of a 2nd sum processing 14) via a coefficient processing 27. The output of the sum processing 36 is referred to as a right output Rout. Thus, suppression of a low frequency component can be realized by summing the low frequency component of one channel signal to the signal of the other channel through the use of principles that the signals between both the channels at a low frequency are almost opposite in the phases and the amplitude of the signals is almost the same. Thus, an undesirable listening sense can be reduced due to an emphasized low frequency component in the feedback loop.
