Document Type and Number:
WIPO Patent Application WO/2023/241205
Kind Code:
A1
Abstract:
An audio processing method and apparatus (555), and an electronic device (500), a computer-readable storage medium (550) and a computer program product. The method comprises: performing sub-band decomposition on an audio signal, so as to obtain a low-frequency sub-band signal and a high-frequency sub-band signal of the audio signal (101); performing feature extraction on the low-frequency sub-band signal, so as to obtain a low-frequency feature of the low-frequency sub-band signal (102); performing high-frequency analysis on the high-frequency sub-band signal, so as to obtain a high-frequency feature of the high-frequency sub-band signal (103), wherein the feature dimension of the high-frequency feature is lower than the feature dimension of the low-frequency feature; and performing quantization and coding on the low-frequency feature, so as to obtain a low-frequency code stream of the audio signal, and performing quantization and coding on the high-frequency feature, so as to obtain a high-frequency code stream of the audio signal (104).
