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 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.
