AUDIO DATA QUANTIZATION DEVICE, AUDIO DATA DEQUANTATION DEVICE AND RELATED METHODS Russian patent published in 2023 - IPC G10L19/38 

FIELD: computer engineering.

SUBSTANCE: processing audio data. The method includes applying vector quantization of the first and second stages to the first set and second set of the first frame, while the audio information elements comprise, for the second frame of a multi-channel audio signal, a third set of average scaling parameters and a fourth set of side scaling parameters, and applying vector quantization of the first and a second stage to a third set of average scaling parameters, and applying the second stage vector quantization to the fourth set of side scaling parameters, and not applying the first stage vector quantization to the fourth set of side scaling parameters.

EFFECT: reduced delay when encoding and decoding audio data.
