Abstract
A stereophonic sound producing apparatus employs four speakers, a background-sound input signal and input-sound signals, to provide an on-the-spot "live action" feeling. The sounds are combined and varied such that a sound such as an artillery shell has a simulated sound and an aurally simulated movement discernible to a human ear. Mixers and attenuators are used, so that a digital "1" or "0" signal serves to operate the on-the-spot "live action" sound effects. A cockpit is provided, together with a video display. A video signal and/or background sound signal is provided by a digitally encoded disk.
