+# DrumSep (ONNX) — Gridshift mirror
+
+Drum-element separation model (kick / snare / cymbals / toms) in ONNX format,
+moved from `philippherzig/drumsep-onnx` to
+[Gridshift Studio](https://huggingface.co/gridshiftstudio) org for
+release-pipeline consistency.
+
+Weights and format are unchanged from the previous repository. The original
+upstream is [inagoy/drumsep](https://github.com/inagoy/drumsep),
+a DemucsHT fine-tune on drum stems.
+
+## Usage
+
+Consumed by [Gridshift](https://gridshift.studio)'s drum-element separation
+feature via the Rust stem-splitter crate. The `drumsep_manifest.json` in this
+repo lists the ONNX model file with SHA-256 for integrity verification.
+
+- **Audio format:** 44.1 kHz stereo, 1 764 000 samples per inference window
+- **Stems:** kick, snare, cymbals, toms
+- **Format:** ONNX (opset 14)
+- **File size:** ~335 MB
+
+## License and attribution
+
+Inherited MIT license from the upstream `inagoy/drumsep` project. The ONNX
+conversion was done from the original HDemucs checkpoint using
+`torch.onnx.export` (see `app/rust/drum-separation/convert_drumsep_to_onnx.py`
+in the Gridshift source tree).
