QSound is a 3D sound processing software created by QSound Labs. It produces 3D virtual audio effects of multiple audible sources, including music and sounds. Its most notable use was for Capcom's arcade games. The first game that Capcom used QSound for was Super Street Fighter II: The New Challengers, in 1993. The last game that they used it for was probably Dimahoo, which was published and distributed by Capcom and developed by Eighting. I think it was released in 2000. I’m thinking that QSound Labs and Capcom should bring back QSound, not only for Capcom's games, but for many other things. They should bring back the original jingle for Capcom's games.
