AUDIO PLAYBACK DEVICE AND AUDIO PLAYBACK METHOD

摘要

An audio playback device which plays back an audio object including an audio signal and playback position information indicating a position in a three-dimensional space at which a sound image of the audio signal is localized, includes: at least one speaker array; a converting unit which converts playback position information to corrected playback position information which is information indicating a position of the sound image on a two-dimensional coordinate system based on a position of the at least one speaker array; and a signal processing unit which localizes the sound image of the audio signal included in the audio object according to the corrected playback position information.
