Abstract
An audio processing system and an audio processing method thereof are provided. A first audio signal and at least one second audio signal from different directions are received by audio receivers. A first component signal and a second component signal are calculated by separating the first audio signal. A third component signal and a fourth component signal are calculated by separating the second audio signal. A major voice information is obtained by calculating the first component signal and the third component signal. A non-major voice information is obtained by calculating the second component signal and the fourth component signal. The non-major voice information is subtracted from the first audio signal to obtain a calculation result. The calculation result and the major voice information are added to obtain a major voice signal in the first audio signal and the at least one second audio signal.
