Abstract: An input signal includes a channel-based audio signal and an object-based audio signal, and an audio encoding device includes an audio scene analysis unit configured to determine an audio scene from the input signal and detect audio scene information; a channel-based encoder that encodes the channel-based audio signal output from the audio scene analysis unit; an object-based encoder that encodes the object-based audio signal output from the audio scene analysis unit; and an audio scene encoding unit configured to encode the audio scene information.

Abstract: An audio reproduction apparatus includes: a signal processing unit that converts an audio signal into N channel signals, where N is an integer greater than or equal to 3; and a speaker array including N speaker elements that respectively output the N channel signals as reproduced sound, wherein the signal processing unit includes: a beam formation unit that performs a beam formation process of resonating the reproduced sound output from the speaker array at a position of one ear of the listener; and a cancellation unit that performs a cancellation process of preventing the reproduced sound output from the speaker array from reaching a position of the other ear of the listener.

Abstract: 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.
