AUDIO ENCODING METHOD AND AUDIO DECODING METHOD Russian patent published in 2023 - IPC G10L19/08 

FIELD: computer technology for processing audio data.

SUBSTANCE: by receiving an encoded bitstream generated by an audio encoder, wherein the encoded bitstream includes encoded multichannel input audio data and processing state metadata, including a volume value; decoding the encoded multichannel input audio data to obtain decoded multichannel audio data; receiving signalling data indicating whether or not to perform volume normalization of the decoded multichannel input audio data; when said signalling data indicates to perform volume normalization of the decoded multichannel audio data: obtaining a volume value from the processing state metadata; and normalizing the volume of said decoded multichannel audio data according to the volume value to provide output audio data; when said signalling data indicates not to perform volume normalization of the decoded multichannel audio data: disabling performing volume normalization.

EFFECT: improving the quality of processing and eliminating the characteristic features in the media data when presenting the contents of the media data.
