The present invention relates to the technical field of communications. Disclosed are an audio data processing method device and system. The method comprises: obtaining a noise frame of an audio signal and resolving the current noise frame into a noise low band signal and a noise high band signal; coding and transmitting the low band signal according to a first discontinuous transmission mechanism; and coding and transmitting the high band signal according to a second discontinuous transmission mechanism. According to the present invention by processing the high band signal and low band signal in different manners the computation complexity is lowered and coding bits are saved without reducing the subjective quality of a codec; the saved bits contribute to a lower transmission bandwidth or higher overall coding quality. |
