AUDIO ENCODING DEVICE, AUDIO ENCODING METHOD, AUDIO ENCODING SOFTWARE, AUDIO DECODING DEVICE, AUDIO DECODING METHOD AND AUDIO DECODING SOFTWARE Russian patent published in 2017 - IPC G10L19/05 G10L19/09 H03M7/30 

FIELD: acoustics; information technologies.

SUBSTANCE: invention relates to audio encoding and decoding devices. Audio signal transmission device for audio signal encoding includes audio encoding unit, which encodes audio signal, and supplementary information encoding unit, which calculates and encodes supplementary information from predicted signal. Audio signal receiving device for audio code decoding and audio signal output includes audio code buffer, which detects packet loss based on audio packet reception status, audio parameters decoding unit, which decodes audio code, when audio packet is received correctly, supplementary information decoding unit, which decodes supplementary information code, when audio packet is received correctly, supplementary information collecting unit, which collects supplementary information obtained by supplementary information code decoding, missing audio parameters processing unit, which outputs audio parameter, when audio packet loss is detected, and audio synthesis unit, which synthesizes decoded audio from audio parameter.

EFFECT: technical result consists in reduction of delay in audio recovery after packet loss when encoding.
