AUDIO ENCODING DEVICE, AN AUDIO ENCODING METHOD, AN AUDIO ENCODING PROGRAM, AN AUDIO DECODING DEVICE, AN AUDIO DECODING METHOD AND AN AUDIO DECODING PROGRAM Russian patent published in 2020 - IPC G10L19/08 

FIELD: data processing.

SUBSTANCE: invention relates to encoding audio signals. Technical result is achieved by encoding side information, where side information is calculated from a predictive signal for calculating the predicted value of the audio parameter in order to synthesise the encoded audio, and encoding side information, wherein side information comprises information indicating accessibility of side information, wherein the additional information is received as an audio parameter on the decoding processing side when the reliability of the predicted value of the calculated audio parameter is low.

EFFECT: technical result consists in ensuring restoration of sound quality without increasing algorithmic delay, when packet loss occurs when encoding audio.
