Patent Document 1 assumes the former case, and the position of the 360 ° sound image is displaced around the user. However, in the latter case, applying Patent Document 1 is not necessarily effective. For example, as shown in FIG. 8 (a), when the position of the 360 ° sound image is displaced around the customer A in the club floor F away from the center of the floor F, the sound image is out of the displacement range. Customer B who is in the position cannot realize that the sound is turning. In addition, there may be a need to intentionally shift the position of the sound image around a specific customer. However, in the technique of Patent Document 1, the center position such as the customer A or the customer B may be varied. Can not.

However, the technology of Patent Document 1 cannot cope with the need to change the position of the sound image in the same direction as viewed from the center of the floor F. Thus, the conventional sound field localization control has a problem that the sound image cannot be localized at an arbitrary position in the listening area, and a sufficient effect cannot be obtained in an environment where the user moves around such as a club floor. .

The user can instruct the position of the sound image on the XY plane of the listening area E1 by arbitrarily moving the operation pointer P on the XY area image 81. FIG. 6 is a diagram illustrating an example of a moving operation of the operation pointer P on the XY area image 81. As shown in FIG. 6A, the operation pointer P is moved diagonally, or as shown in FIG. 5B, an arc having an arbitrary radius is drawn around an arbitrary point on the XY area image 81. It is possible to move the operation pointer P. When the operation pointer P is moved, the control unit 210 causes the audio signal transmission unit 22 and / or the signal processing so that the position of the operation pointer P on the XY area image 81 corresponds to the position of the sound image in the listening area E1. The apparatus 30 is controlled (as a result, the amplifier 40 and the speaker 50 are also controlled). As a control method, a known sound field localization control technique such as level adjustment (volume control) by each audio signal processing unit 33 can be applied.

Specifically, the area shape is set by inputting a numerical value or drawing an rectangle on the touch panel 73 by the operator. The control unit 210 determines the position of the sound image on the XY plane of the listening area E1 according to the operation pointer P (operation position) operated by the XY direction operation unit 223 and the area shape set by the area shape setting unit 240. Control. As described above, since the shape of the XY area image 81 is fixed regardless of the setting of the area shape setting unit 240, when the aspect ratio of the XY area image 81 and the aspect ratio of the listening area E1 on the XY plane are different, The amount of displacement of the sound image in the listening area E1 with respect to the amount of movement of the operation pointer P on the XY area image 81 differs between the direction and the Y direction. Therefore, the control unit 210 performs control to vary the position of the sound image in consideration of the set aspect ratio of the listening area E1.
