Audio Playground models (Demucs v4, ONNX)

Browser-ready versions of Meta's Hybrid Transformer Demucs, used by Rabiat's Audio Playground. The app runs them on the visitor's GPU with ONNX Runtime Web, so no audio ever leaves the device.

File	Stems	Size
htdemucs.onnx	vocals, drums, bass, other	86 MB

Only the neural network is exported; the STFT and inverse STFT run in JavaScript. Weights are stored as float16 and cast to float32 inside the graph. Output matches PyTorch within 54-57 dB.
