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 15):
A decoder comprising:\n a non-transitory memory for storing computer-executable instructions; and a processor operatively coupled to the non-transitory memory, the processor being configured to execute the computer-executable instructions to:\n obtain a current silence insertion descriptor (SID) of the audio signal, wherein the current SID comprises a noise low-band parameter; \n determine whether the current SID comprises a noise high-band parameter; \n decode the current SID to obtain the noise low-band parameter according to the determination, wherein a noise high-band parameter is extrapolated according to the decoded noise low-band parameter and a ratio of an energy of a previous noise high-band signal to an energy of a previous noise low-band signal when wherein the current SID does not comprise the noise high-band parameter, wherein the previous noise high-band signal and the previous noise low-band signal were associated with the audio signal when a last time a previous SID comprising a noise high-band parameter was received before the current SID, wherein \n a first comfort noise (CN) frame is obtained according to the decoded noise low-band parameter and the extrapolated noise high-band parameter; and \n wherein the current SID is decoded to obtain the noise high-band parameter and the noise low-band parameter when the current SID comprises the noise high-band parameter, \n a wherein a second CN frame is obtained according to the decoded noise high-band parameter and the decoded noise low-band parameter.
