AUDIO ENCODING DEVICE, AUDIO ENCODING METHOD, AUDIO ENCODING PROGRAM, AUDIO DECODING DEVICE, AUDIO DECODING METHOD AND AUDIO DECODING PROGRAM Russian patent published in 2021 - IPC G10L19/08 G10L19/09 

FIELD: computer technology.

SUBSTANCE: invention relates to the field of computer technology for processing audio data. The expected result is achieved due to the audio encoding stage, at which the audio signal is encoded; the stage of encoding side information, at which side information is calculated from the forecast signal to calculate the predicted value of the audio parameter for synthesizing decoded audio and the side information is encoded, while the side information contains a different number of bits depending on the availability of side information.

EFFECT: ensuring the restoration of sound quality without increasing the algorithmic delay when a packet is lost during audio encoding.
