Abstract
An audio decoding method includes: obtaining an encoded bitstream; performing bitstream demultiplexing on the encoded bitstream to obtain a first coding parameter of a current frame; performing bitstream demultiplexing on the encoded bitstream based on a configuration parameter for tonal component coding to obtain a second coding parameter of the current frame, where the second coding parameter of the current frame includes a tonal component parameter; obtaining a first high frequency band signal and a first low frequency band signal of the current frame based on the first coding parameter; obtaining a second high frequency band signal of the current frame based on the second coding parameter and the configuration parameter for tonal component coding; and obtaining a 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.
