FIELD: computer equipment for processing audio data.
SUBSTANCE: encoding the side information, wherein the side information is calculated from the predictive signal, and the side information is intended to calculate the predicted value of the audio parameter during decoding, whereas, when it is determined that the side information is available in accordance with the index representing the characteristics of the target frame encoding, information representing that side information is available is included in the side information index, whereas at the step of encoding the side information, the side information index and the side information are used as codes of the side information in the audio packet for the encoding target frame.
EFFECT: restoration of sound quality without increasing the algorithmic delay when a packet is lost during audio encoding.
