| Term | Description | |------|-------------| | | Proprietary audio chip (also known as “QSound DSP”) used in several N64 titles (e.g., Star Fox 64 , GoldenEye 007 ). It offers 16‑bit stereo output, DSP‑based filtering, and a pseudo‑3‑D positioning algorithm based on per‑voice delay and attenuation. | | High‑Level Emulation (HLE) | Re‑creates the observable behaviour of a hardware component by implementing its functional API rather than simulating its internal circuitry cycle‑by‑cycle. HLE is faster and easier to maintain but may miss edge‑case hardware quirks. | | Low‑Level Emulation (LLE) | Accurate, cycle‑accurate simulation of the original hardware. Offers perfect compatibility but at a high CPU cost. | | qsound‑hle | An HLE library that reproduces the audible output of the QSound chip using a small set of DSP primitives, a voice‑mixing engine, and a 3‑D positioning algorithm derived from reverse‑engineered documentation. |

contains the original disassembly and C-ports of the QSound program. It explains that the chip is a DSP16A processor qsound-hle.zip file

The Capcom CPS-2 board utilized a custom QSound chip (often labeled as a DL-1425 or similar ASIC). This chip was essentially a primitive sampler and effects processor. It took sample data (PCM) and processed it through a specialized filter bank to create a wider, "pseudo-stereo" soundstage. | Term | Description | |------|-------------| | |

The DSP processing runs voice mixing, on the interleaved stereo buffer.
