<P>PROBLEM TO BE SOLVED: To provide an information processing program, an information processor, an information processing system, and an information processing method, for identifying sound from sound sources located in different directions. <P>SOLUTION: A game device corrects the sound of the sound sources located behind a virtual camera by applying a frequency filter to the sound sources. Specifically, the game device calculates an angle between the imaging direction of the virtual camera and a direction from the virtual camera toward the sound source. When the absolute value of the angle is 90 degrees or more, the game device calculates a filter value according to the angle. The game device also corrects the filter value according to a distance between the virtual camera and the sound source. The game device applies a low-pass filter corresponding to the filter value to the sound of the sound source. <P>COPYRIGHT: (C)2013,JPO&INPIT |
