AUDIO ENCODING DEVICE, AUDIO ENCODING METHOD, AUDIO ENCODING PROGRAMME, AUDIO DECODING DEVICE, AUDIO DECODING METHOD AND AUDIO DECODING PROGRAMME Russian patent published in 2018 - IPC G10L19/05 G10L19/09 

FIELD: physics.

SUBSTANCE: audio signal transmission device for encoding an audio signal includes an audio encoding unit that encodes an audio signal and a side information encoding unit that calculates and encodes side information from the prediction signal. The receiving device of the audio signal to decode the audio-code and audio signal output includes a buffer of the audio-code that detects a packet loss based on the reception status of the audio pack, a decoding unit of audio-parameters that decodes the audio-code, when the audio pack is adopted correctly, a decoding unit of side information, which decodes the side information, when the audio pack is adopted correctly, a collection unit of side information, which collects the side information obtained by decoding side information, a processing unit of missing audio-parameters and an audio synthesis unit.

EFFECT: restoration of sound quality without increasing the algorithmic delay, when there is a loss of the packet when encoding audio.
