Abstract
An audio encoding device (A) corrects initial gain information calculated for an arbitrary frame, based on gain information of a stored past frame, thereby calculating gain information to be used in the frame. The audio encoding device (A) encodes the calculated gain information as a difference from the gain information of the past frame. An audio decoding device (A) receives the differential gain, and calculates the gain of the arbitrary frame based on the gain used in the past frame, thereby generating a decoded audio signal.
