Abstract
A crosstalk cancellation system for preserving quality of sound and the parameter determining method thereof. The system can cancel a two-channel audio signal without compensating a frequency response of an ipsilateral HRTF. The method includes providing an audio signal input device for inputting the two-channel audio signal, modeling a relation between parameters of the crosstalk cancellation system and a head related transfer function (HRTF) to thereby obtain an output transfer impulse response, setting contralateral parts of the output transfer impulse response approximate to zero, setting ipsilateral parts of the output transfer impulse response equal to a delay of ipsilateral head related impulse responses (HRIRs) corresponding to the HRTF, and performing an inverse operation to compute the parameters of the crosstalk cancellation system.
