demucs-onnx

0.3.3

Run and export HT-Demucs / Demucs music source separation as ONNX. Pure numpy + onnxruntime inference (no PyTorch). Supports htdemucs_ft (4-stem bag), htdemucs (single-file 4-stem), and htdemucs_6s (6-stem with guitar + piano). Karaoke / acapella CLI, browser-demo scaffolder, auto-resampling, auto execution provider routing, fp16-weight downloads, MP3 output. Fixes the 4 blockers that prevent vanilla torch.onnx.export from working on htdemucs.
