PROBLEM TO BE SOLVED: To provide a technology for preventing a sound volume from becoming high and a sound from becoming noisy even if a listener is out of a sweet spot during trans-aural reproduction.SOLUTION: A binaural acoustic signal is acquired. Crosstalk cancel processing is performed on the binaural acoustic signal, thereby producing a crosstalk cancel processed binaural acoustic signal. The binaural acoustic signal is delayed, thereby producing a delayed binaural acoustic signal. If both ears of the listener are located within the sweet spot, the crosstalk cancel processed binaural acoustic signal is outputted and if at least one of both the ears is located outside of the sweet spot, the delayed binaural acoustic signal is outputted. |
