| # ITO-Master (white-box) — ONNX export for in-browser mastering |
|
|
| ONNX export of the **white-box** ITO-Master music-mastering model, for running the parameter |
| predictor in the browser with ONNX Runtime Web. Used by the |
| [audio-master](https://huggingface.co/spaces/kramp/audio-master) Space. |
|
|
| - `fxencoder.onnx` — reference audio `[1,2,N]` (44.1 kHz stereo) → style embedding `[1,2048]` |
| - `mastering_tcn.onnx` — input audio `[1,2,N]` + embedding `[1,2048]` → **46** normalized |
| parameters `[1,46]` in `[0,1]` |
| - `config.json` — the exact parameter order and per-parameter min/max for de-normalization |
| (`value = norm*(max-min)+min`). The differentiable EQ / distortion / multiband-comp / gain / |
| imager / limiter chain is re-implemented natively (Web Audio); only the learned predictor is |
| exported here. |
|
|
| Exported with a Hugging Face Job (`torch.onnx.export`, opset 17), validated against PyTorch |
| (max abs error < 1e-3) with `onnxruntime`. |
