Abstract
Provided is an audio transcoding method, including: () performing entropy decoding on a first audio stream with a first bitrate, to obtain an audio feature parameter and an excitation signal of the first audio stream, the excitation signal being a quantized audio signal; () obtaining a time-domain audio signal corresponding to the excitation signal based on the audio feature parameter and the excitation signal; () re-quantizing the excitation signal and the audio feature parameter based on the time-domain audio signal and a target transcoding bitrate, to obtain a target excitation signal and a target audio feature parameter; and () performing entropy coding on the target audio feature parameter and the target excitation signal, to obtain a second audio stream with a second bitrate, the second bitrate being lower than the first bitrate.
