HTDemucs (ONNX Runtime) — Gridshift mirror
This is a mirror of gentij/htdemucs-ort,
re-hosted under the Gridshift Studio 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'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)

The conversion to ONNX Runtime was done by gentij;
we redistribute that conversion without modification.
