Simulation System, Sound Processing Method And Information Storage Medium

The present invention provides a simulation system, a sound processing method and an information storage medium which can generate an appropriate sound field even though the positions and the directions of the users change. The simulation system comprises an input processing part for obtaining the position and direction information of the users who move in an actual space in which first to M-th loudspeakers are configured; a sound processing part for carrying out the sound balance adjustment on the first to M-th loudspeakers even on the condition that the positions and directions of the virtual users corresponding to the users in the virtual space along with the change of the directions and the positions of the users in the actual space, relative to the following first to N-th positions keeping the specified relative position relation of the virtual users PV, thereby setting the first to N-th virtual loudspeakers. The first to N-th virtual loudspeakers are used to form a sound field based on a virtual sound s
