AUDIO PLAYBACK DEVICE, PLAYBACK METHOD THEREOF AND PLAYBACK PROGRAM

摘要

PROBLEM TO BE SOLVED: To optimally reduce the difference of an inter-music sound-volume for each audio data.SOLUTION: The audio playback device comprises: sound-pressure information calculating means for calculating sound-pressure information on audio data to be played back on the basis of the audio data; sound-pressure information storing means for storing the sound-pressure information calculated by the sound-pressure information calculating means in association with the audio data to be played back; sound-volume adjustment value calculating means for calculating a sound volume adjustment value on the basis of the sound-pressure information stored by the sound-pressure information storing means and set sound-volume information; decode processing means for decoding the audio data to be played back; and fade processing means for performing fade processing on the basis of the sound-volume adjustment value calculated by the sound-volume adjustment value calculating means and the audio data decoded by the decode processing means to produce the audio data after sound-volume adjustment.
