Abstract:
A method for processing audio data includes obtaining a noise frame of an audio signal, and decomposing the current noise frame into a noise low-band signal and a noise high-band signal; and encoding and transmitting the noise low-band signal by using a first discontinuous transmission mechanism, and encoding and transmitting the noise high-band signal by using a second discontinuous transmission mechanism. According to the present disclosure, different processing manners are used for the high-band signal and the low-band signal, calculation loads and encoded bits may be saved under a premise of not lowering subjective quality of a codec, and bits that are saved may help to achieve an objective of reducing a transmission bandwidth or improving overall encoding quality.

Claim (Index 10):
The method according to  claim 7 , wherein the method further comprises:\n multiplying noise high-band signals of subsequent L frames starting from the current SID by a smoothing factor to obtain a new weighted average energy of the extrapolated noise high-band signals, wherein history frames adjacent to the current SID are encoded speech frames, wherein the smoothing factor is greater than 0 and smaller than 1, wherein a part of high-band signals that are decoded from the encoded speech frames or an average energy of high-band signals is smaller than a part of the noise high-band signals that are extrapolated or an average energy of noise high-band signals, and wherein the first CN frame is obtained based on the decoded noise low-band parameter, the synthesis filter coefficient of the current noise high-band signal, and the new weighted average energy of the extrapolated noise high-band signals.
