QSound was a spatial audio processing technology developed in the 1990s that enhanced stereo playback to create a wider, more immersive soundstage using psychoacoustic cues. It was used in arcade systems, video game consoles, and PC soundcards to make audio appear to come from positions beyond the physical speaker locations. "qsound-hle.zip" refers to an HLE (high-level emulation) implementation of QSound—typically a packaged set of code or assets used by emulator projects to reproduce the QSound audio processing behavior without reimplementing the original hardware at the lowest level.
The distinctive feature of QSound is its "surround sound" capability, which places audio sources in a stereo field wider than the physical speaker separation. qsound-hle.zip rom
