Classification: CPC G | IPC G

Claim 18:
19. A non-transitory computer-readable storage medium storing computer instructions that, when executed by one or more processors of an audio encoder, cause the audio encoder to be configured to:
obtain an encoded bitstream;
perform bitstream demultiplexing on the encoded bitstream to obtain a high frequency band parameter of a current frame of an audio signal, wherein the high frequency band parameter comprises a combined location and quantity parameter and either an amplitude or an energy of a tone component comprised in a high frequency band signal of the current frame, and wherein a high frequency band corresponding to the high frequency band signal comprises at least one frequency region;
obtain a second combined location and a quantity parameter in a current frequency region in the at least one frequency region;
parse the encoded bitstream based on the second combined location and the quantity parameter to obtain a second amplitude parameter or a second energy parameter of the tone component in the current frequency region;
obtain a reconstructed high frequency band signal of the current frame based on the high frequency band parameter; and
obtain an audio output signal of the current frame based on the reconstructed high frequency band signal.
