Audio decoding methods, audio decoders, and computer-readable storage media

Abstract

The invention relates to a method for decoding audio, an audio decoder, and a computer-readable storage medium. The audio decoding method includes: receiving the encoded bit stream (401); performing bit stream demultiplexing on the encoded bit stream to obtain the first code parameter of the current frame of the audio signal; performing bit stream demultiplexing on the encoded bit stream based on the configuration parameter to encode the tonal component to obtain the second code parameter of the current frame, where the second code parameter of the current frame includes the tonal component parameter of the current frame (402); Receive the first high-band signal and the first low-band signal of the current frame based on the first coding parameter (403); receive the second high-band signal of the current frame based on the second coding parameter and the configuration parameter to encode the color component (404); and receive the decoded signal of the current frame based on the first high-frequency band signal, the second high-frequency band signal, and the first low-frequency band signal (405). Audio decoding methods and related equipment improve the quality of audio signal decoding.
