Abstract
Sound location information provided in the game program of a video game is employed by a sound processor to produce two-channel sound signals that provide an apparent location of a sound source to the video game player that need not correspond to the actual locations of the loudspeakers. The sound processor processes the sound signals produced by an audio synthesizer of the kind known for use in a video game system in accordance with audio information contained in the game program cartridge. The sound processor can be connected to the central processing bus along with the audio synthesizer. Alternatively, the sound processor can be connected to a separate audio synthesizer, both of which are connected to the video game system through a parallel bus provided therein for communication with the central processing unit bus. In another approach, the sound processor and synthesizer are connected to the video game system through a serial or parallel port provided therein for communication with the central processing unit.
