AB  - Three-dimensional panning is an essential tool for production of 3D sound material. The typical method is an amplitude panning. The amplitude panning generates the weighting coefficients on the basis of the direction of virtual sound source (desired direction) and the directions of loudspeakers, or the distances between the virtual source and each loudspeaker. It then distributes the weighted signal of the corresponding sound into loudspeakers. The amplitude panning sometimes brings blurred image and deteriorates the timbre of sound. In this paper we propose the new method that optimizes the shape of the wave surface synthesized by multiple loudspeakers. The computer simulation with the frontal six-loudspeaker system showed that the new method achieved the improvement of the reproduced wave surface of sound and its frequency response.
