+# HTDemucs (ONNX Runtime) — Gridshift mirror
+
+This is a mirror of [gentij/htdemucs-ort](https://huggingface.co/gentij/htdemucs-ort),
+re-hosted under the [Gridshift Studio](https://huggingface.co/gridshiftstudio) organization
+so that the desktop app's model-distribution pipeline remains stable across
+upstream changes.
+
+**Weights, format, and license are unchanged from upstream.**
+
+## Usage
+
+Consumed by [Gridshift](https://gridshift.studio)'s stem-separation feature via
+the Rust stem-splitter crate (`reqwest` + `onnxruntime`). The `manifest.json`
+in this repo lists the ONNX model file with its SHA-256 and size for
+client-side integrity verification.
+
+- **Audio format:** 44.1 kHz stereo, 343 980 samples per inference window
+- **Stems:** drums, bass, other, vocals
+- **Format:** ONNX Runtime `.ort` (converted from PyTorch HTDemucs)
+- **File size:** ~200 MB
+
+## License and attribution
+
+Apache-2.0, inherited from the upstream Demucs project by Facebook Research.
+The conversion to ONNX Runtime was done by [gentij](https://huggingface.co/gentij);
+we redistribute that conversion without modification.
+
+Please cite upstream Demucs if you use this model:
