Abstract (en)
An audio encoding device for encoding an audio signal consisting of a plurality of frames, the audio encoding device comprising: an audio encoding unit for encoding the audio signal; and an auxiliary information encoding unit for estimating and encoding auxiliary information about a temporal change of power of the audio signal, the auxiliary information being used in packet loss concealment in decoding of the audio signal, wherein the auxiliary information encoding unit estimates and encodes quantized transient power and a flag of sudden change of power, as the auxiliary information.
