Abstract

There is provided a surround-sound system in which the output direction of a sound beam of each channel in a speaker array can be optimized without requiring a user to make any troublesome operation. A parameter setting control portion 6 controls to output sound beams from a speaker array 1 and rotate the output directions of these sound beams. In addition, based on change of sound pressure sensed by a microphone 7 when the output directions of the sound beams are rotated, the parameter setting control portion 6 determines the output directions of sound beams of at least a part of a plurality of channels in the speaker array 1. The parameter setting control portion 6 determines the output directions of sound beams of the other channels based on the output directions of the channels determined based on the change of sound pressure.
