Abstract
Abstract A system capable of synthesizing multi-channel sound for a computer includes a sound generator for each audio channel. A circuit provides a programmable delay so that one generator produces sound in one channel that is delayed with respect to the sound in the other channel. Multiple generators may be provided in each channel with each such generator having an independently programmable delay circuit associated therewith.
