PROBLEM TO BE SOLVED: To install a virtual sound source at a desired position with intuitive operation in an audio system having a plurality of speakers.SOLUTION: A smart phone is used as means for setting speaker positions or the like with respect to an audio amplifier which sorts audio signals corresponding to a virtual sound source into a plurality of speakers respectively on the basis of positions of the respective speakers set by a user and a position of the virtual sound source. The smart phone performs processing which converts angle information showing a posture of its own terminal at the time when operation for setting the speaker positions is performed into position information showing speaker positions in a coordinate space having a listening point position as an original point and transmits the information and processing which converts angle information showing a posture of its own terminal at the time when operation for setting the position of the virtual sound source is performed into position information showing the position of the virtual sound source in the coordinate space and transmits the information. |
