Abstract
An audio coding method includes obtaining a current frame that includes a high-frequency band signal and a low-frequency band signal; performing first coding on the high-frequency band signal and the low-frequency band signal to obtain a first coding parameter; determining a spectrum reservation flag of each frequency bin of the high-frequency band signal, where the spectrum reservation flag indicates whether a first spectrum corresponding to the frequency bin is reserved in a second spectrum corresponding to the frequency bin; and performing second coding on the high-frequency band signal based on the spectrum reservation flag of each frequency bin of the high-frequency band signal to obtain a second coding parameter, where the second coding parameter indicates information about a target tonal component of the high-frequency band signal.
