DrumSep (ONNX) — Gridshift mirror

Drum-element separation model (kick / snare / cymbals / toms) in ONNX format, moved from philippherzig/drumsep-onnx to Gridshift Studio org for release-pipeline consistency.

Weights and format are unchanged from the previous repository. The original upstream is inagoy/drumsep, a DemucsHT fine-tune on drum stems.

Usage

Consumed by Gridshift'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).
