RoFormer separation models run inside this tab with WebGPU. Nothing is uploaded and no server is involved. Pick a model, drop a bounce, play each stem and download it as WAV.
Models download directly from Hugging Face on first use, are checked against a pinned SHA-256, and are saved in this browser (resumable if interrupted). After the first run the tool works offline. You can clear the models at any time.
Best on desktop Chrome or Edge with a dedicated GPU. Without WebGPU it falls back to the CPU (multi-threaded where your browser allows it), which is slower. Use the Fast preview model in that case.
