PROBLEM TO BE SOLVED: To provide a device performing sound effect addition in a space, by making it possible to change the localization direction of a sound image continuously.SOLUTION: A control unit 100 normally sets the coefficient A in a coefficient unit 45 to "0" under a normal condition. The results of addition from an addition unit 30 are written in a buffer 46 sequentially. When an event number is given, the control unit 100 sets the coefficient A in a coefficient unit 45 to a value other than "0". The buffer 46 outputs the signals that have been written therein, and inputs a signal obtained by multiplying the coefficient A in the coefficient unit 45 to a direction control unit 60 performing the changing control of the localization direction of a sound image. |
