FIELD: data processing.
SUBSTANCE: invention relates to audio decoding and, more particularly, to the selection of a packet loss masking procedure when decoding audio. In accordance with an exemplary embodiment of the present invention, there is disclosed a method and apparatus for such to select a packet loss masking procedure for a lost audio frame of a received audio signal. Method for selecting a packet loss masking routine comprises detecting an audio type of an audio frame received and determining a packet loss masking procedure based on the audio type. In the method, audio type detection comprises determining the stability of the spectral envelope of the signals of the received audio frames.
EFFECT: ensuring a high quality of the restored audio signal after a packet loss.
