Abstract: An audio processing method and apparatus, including decomposing an audio signal into a low-frequency subband signal and a high-frequency subband signal, obtaining a low-frequency feature of the low-frequency subband signal, obtaining a high-frequency feature of the high-frequency subband signal, feature dimensionality of the high-frequency feature being lower than feature dimensionality of the low-frequency feature, performing quantization encoding on the low-frequency feature to obtain a low-frequency bitstream of the audio signal, and performing quantization encoding on the high-frequency feature to obtain a high-frequency bitstream of the audio signal.
