Capcom integrated this technology into their CPS-2 hardware (using the DL-1425 chip, a DSP16A processor) to make sound effects, such as a punch in Street Fighter II , feel like they originated from specific locations outside the standard left/right speaker stage. The technology was also famously used in music albums, including Madonna’s "The Immaculate Collection" and Michael Jackson's "Dangerous". What is qsound_hle? (The Emulation) qsound_hle stands for . In MAME emulation, there are two primary approaches: The technology was also famously used in music
qsound_hle intercepts that command. It looks up the audio sample in a pre-extracted table. Then, using a modern software DSP algorithm (often a modified version of the QSound patent math), it reconstructs the 3D audio instantly.
