Capcom Q-Sound QSound is a spatial audio technology developed by QSound Labs and famously used by Capcom in many of its arcade games starting in the early 1990s. It simulates 3D positional audio using stereo speakers, creating a more immersive sound experience. Capcom’s CPS-1' and 2 arcade system used QSound for enhanced music and sound effects in games.
