[Problem] To provide a technology capable of suppressing sound leakage to the outside of a room even when a user listens to audio in the room at a preferred sound volume. [Solution] This multi-channel audio device 1 performs sound output on audio playback signals from channels through respective playback speakers 2, and performs sound output on antiphase signals of the audio playback signals through an antiphase speaker 3. The attenuation rates and the delay times of the audio playback signals output from the respective playback speakers 2 at the installation position of the antiphase speaker 3 are stored in advance, and during the audio playback, the antiphase signals of the audio playback signals of the respective channels are attenuated on the basis of the respective attenuation rates, are delayed on the basis of the respective delay times, and are output as sound from the antiphase speaker 3.
An audio system, comprising:
An audio device for outputting an audio reproduction signal to a reproduction speaker, comprising:
A program for causing a computer to function as an audio device for outputting an audio reproduction signal to a reproduction speaker, the program causing the computer to function as:
An audio reproduction method for reproducing audio by an audio system including an audio device configured to output an audio reproduction signal and a reproduction speaker configured to output, in the form of audio, the audio reproduction signal output from the audio device, the audio reproduction method comprising:
