The prevent invention improves a processing speed by combining simple sound source species with a basic configuration and processing the combination as a single sound source, when sound sources and sound fields are placed and formed in a three-dimensional virtual space. As a sound source object that corresponds to a river 21, a sound source object 21x with a complicated shape that includes sound source objects 21a, 21c and 21e with shapes of rectangular parallelepipeds and sound source objects 21b and 21d with shapes of triangular prisms are placed. The sound source objects 21a to 21e have the same identification numbers and have sound data related to a babbling sound of the river. In a case where the sound source object 21c is the closest to a player character, sound generation processing is executed based on the sound source object 21c. |
