PROBLEM TO BE SOLVED: To provide a surround sound field reproduction system that can localize a sound image in matching with a direction in which a viewing/listening person views a video image in front when the viewing/listening person sets the direction of the video image to view it in front of the person. SOLUTION: The surround sound field reproduction system is provided with horizontal panning pots HP1-HP6 that receive audio signals from microphones H1-H6 placed in a horizontal direction and control horizontal direction localization in interlocking with each other and a vertical panning pot VP that receives audio signals from microphones T, B installed in a vertical direction and controls localization in the vertical direction. The horizontal panning pots HP1-HP6 distribute levels to mixing buses L, Cm, R, Ls, Rs arranged corresponding to surround reproduction output channels L, C, R, Ls, Rs and the vertical panning pot VP changes a level distribution of the audio signal in the vertical direction to provide an output of the result to an output channel for a front center. |
