The author released an ultra-fast C++ implementation for **Supertonic 3** within **audio.cpp**, aiming to build a unified local runtime for audio models. ### Key Results - Achieves **200×+ real time** on an **RTX 5090** - Achieves **6×+ real time** on a CPU - TTFT is approximately **47 ms** in CUDA streaming mode - A demo generated roughly **10 hours of audio** for "The Adventures of Sherlock Holmes" in just about **3 minutes** ### Project Direction The author hopes audio.cpp will eventually cover: - TTS - ASR - Voice cloning - Long-form audio generation - Server-like usage The goal is to avoid relying on separate Python environments and custom runtimes for every individual model.
