FIELD: data processing.
SUBSTANCE: invention relates to processing of audio signals. Audio signal processing device comprises a discontinuity detector configured to determine an occurrence of a discontinuity from a sudden increase of an amplitude of decoded audio, obtained by decoding the first audio packet which is received correctly after an occurrence of a packet loss, and a discontinuity corrector for correcting the discontinuity of the decoded audio.
EFFECT: reducing audio discontinuity when restoring a packet at the start point of the audio and increasing the subjective quality of the audio.
