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

FIELD: data processing.

SUBSTANCE: invention relates to means for masking errors in audio encoding/decoding. Audio signal transmission apparatus 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 a prediction signal. Audio signal receiving device for audio code decoding and audio signal output includes audio code buffer, which detects a packet loss based on the audio packet reception state, an audio parameter decoding unit that decodes the audio code, when the audio packet is received correctly, the side information decoding unit that decodes the side information code when the audio packet is received correctly, a side information collecting unit that collects side information obtained by decoding the side information code, a missing audio parameter processing unit, and an audio synthesis unit.

EFFECT: technical result is to restore sound quality without increasing the algorithmic delay, when there is a packet loss when encoding audio.
