AUDIO PROCESSING SYSTEM AND AUDIO PROCESSING METHOD THEREOF

摘要

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.

主权项

1. An audio processing method, adapted to an audio processing system comprising an audio receiving device, wherein the audio receiving device comprises a plurality of audio receivers, the audio processing method comprising the following steps:
receiving a first audio signal and at least one second audio signal from different directions by the audio receivers; calculating a first component signal and a second component signal by separating the first audio signal; calculating a third component signal and a fourth component signal by separating each of the at least one second audio signal; obtaining a major voice information by calculating the first component signal and the at least one third component signal; obtaining a non-major voice information by calculating the second component signal and the at least one fourth component signal; subtracting the non-major voice information from the first audio signal to obtain a calculation result; and adding the calculation result and the major voice information to obtain a major voice signal in the first audio signal and the at least one second audio signal.
