Abstract
A stereophonic sound reproduction system for compensating a low frequency signal and a method thereof, wherein a mono component signal for compensating low frequency signals which are attenuated when removing a crosstalk of inputted left and right signals inputted is calculated using an average value between the left and right signals, left and right compensation gains which are inversely proportional to an absolute value of a power difference value between the first left and right signals, an amplitude of the calculated mono component signal is controlled according to the left and right compensation gains, and thereafter the mono component signal with the controlled amplitude is added to the left and right signals when removing the crosstalk, whereby the left and right signals from which the crosstalk is removed and to which the mono component signal is added are outputted through left and right speakers to thus prevent distortion of the low frequency signals of original stereophonic sound with maintaining a stereophonic sound effect.
