1. A method for processing audio data, comprising:

  • obtaining a noise frame of an audio signal;

    decomposing the noise frame into a noise low-band signal and a noise high-band signal;

    encoding the noise low-band signal by using a first discontinuous transmission mechanism and transmitting the encoded noise low-band signal by using a first discontinuous transmission mechanism; and

    encoding the noise high-band signal by using a second discontinuous transmission mechanism and transmitting the encoded noise high-band signal by using a second discontinuous transmission mechanism, wherein a policy for sending a first silence insertion descriptor frame (SID) of the first discontinuous transmission mechanism is different from a policy for sending a second SID of the second discontinuous transmission mechanism, or a policy for encoding a first SID of the first discontinuous transmission mechanism is different from a policy for encoding a second SID of the second discontinuous transmission mechanism.
