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 9):
The method according to  claim 5 , wherein the ratio is obtained in log-domain, and\n wherein the ratio is represented by a difference between a log-domain energy of the previous noise high-band signal and a log-domain energy of the previous noise low-band signal.
