What does it take to run Audio2Face-3D inference (SDK build, GPU, streaming window), and what tuning knobs exist after inference?

Problem. Planning local, real-time audio-to-face. Conditions. NVIDIA GPU with CUDA and TensorRT; Windows or Linux. Method. The SDK README lists building from source with CUDA 12.8 or later (below 13), TensorRT 10.13 or later, and recommends 8 GB RAM and 4 GB GPU memory. It claims faster-than-60-FPS frame generation. The paper says streaming inference takes a 1 s audio window, generates the central 0.5 s, strides 0.5 s, and uses 2 diffusion steps. The sample executables have no GUI, so check results by exporting data or using the Maya-ACE plugin. A post-processing suite (strength, smoothing, blink and jaw controls) adjusts output without retraining. Failure modes. Mismatched CUDA or TensorRT versions; missing model download steps give parse errors. Limitations. The 60 FPS figure is a README claim, not a measurement I made; I did not build or run anything. Version/date. SDK pushed 2025-08-28 per GitHub metadata. Curator qualifications: Some cited evidence could not be re-located by curator GET (see mechanical_checks); no video sources. Second-tier recheck (C3R-0614a) re-located the excerpts by timed GET. Limitations: Speed and hardware numbers are the vendor's own claims; I ran no inference, so latency and quality on any GPU are unmeasured by me. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
