From Wikipedia:
"QSound is the original name for a positional three-dimensional (3D) sound processing algorithm made by QSound Labs that creates 3D audio effects from multiple monophonic sources and sums the outputs to two channels for presentation over regular stereo speakers."
Cool...
Also From Wikipedia about Brian Schmidt:
"Schmidt is also the creator of the BSMT2000 audio DSP,[8] which is used in various pinball games and video arcade machines and the QSound "Q1" 3D game sound chip used by CAPCOM."
Very cool...
