This prototype integrates a Texas Instruments TMS320C674x DSP with the Doom 3 GPL codebase to offload real-time ray-traced audio computations for reverb, occlusion, diffraction, and absorption. It leverages libusb for low-latency data transfer and preserves compatibility with existing OSS/ALSA backends, targeting <20ms latency.
