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 4):
The method according to  claim 1 , wherein the determining whether to encoding a first SID corresponding to the current noise frame or a second SID corresponding to the current noise frame comprises:\n obtaining a first difference between the log-domain energy of the current noise low-band signal and the log-domain energy of the current noise high-band signal; obtaining a second difference between the log-domain energy of the previous noise low-band signal and the log-domain energy of the previous noise high-band signal; obtaining a third difference between the first difference and the second difference; and comparing an absolute value of the third difference with a preset threshold, wherein the first SID is encoded when the absolute value of the third difference is greater than the preset threshold, and wherein the second SID is encoded when the absolute value of the third difference is less than or equal to the preset threshold.
