Silverdaw Backup Stem Pack — htdemucs fine-tuned (ONNX)

An ONNX export of the Hybrid Transformer Demucs fine-tuned 4-stem model (htdemucs_ft), used by Silverdaw as its backup stem-separation engine. htdemucs_ft is a "bag" of four specialist models — one per source — so vocals / drums / bass / other are all native outputs.

Silverdaw's primary engine is the higher-quality RoFormer pack pair (vocals + rhythm); this model is used when those packs are not installed, or when the user explicitly selects the backup engine.

This repository is a re-host of StemSplitio/htdemucs-ft-onnx so Silverdaw can serve every model it needs from one self-owned location. The weights and the export are unchanged (byte-identical; same SHA-256).

Each file is a self-contained .onnx (fp32 weights, no external .data). fp32 is chosen over the fp16 variants for the CPU execution provider, where fp16 ops are commonly emulated (slower) rather than accelerated.

Intended use

Designed for offline (non-real-time) stem separation inside a desktop DAW. It is not a real-time audio-callback model — run it on a worker/background thread.
