Abstract: A method for synchronously accessing audio data and an audio playback system using the same are provided. The method comprises: providing a first device and a second device; providing an audio common memory in the second device; transmitting an audio data from the first device to the second device when the second device performs an audio playback; writing the audio common memory by the first device and reading the audio common memory by the second device when the first device transmits the audio data to the second device; and performing an interpolation operation by the second device when a difference between a read address value of the second device and a write address value of the first device is different from a predetermined difference.

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.
