htdemucs_6s — WebGPU-compatible ONNX
A constant-folded copy of StemSplitio/htdemucs-6s-onnx
(htdemucs_6s: drums, bass, other, vocals, guitar, piano).
The only change: the original's embedded inverse-STFT contains a ConstantOfShape op that
onnxruntime-web's WebGPU backend cannot run. Because the input window is fixed
(mix [1,2,343980]), that node's output shape is static, so it was folded to a Constant
offline (ONNX Runtime ORT_ENABLE_BASIC). The result is bit-identical to the original
(same mix → stems [1,6,2,343980] I/O) but runs on WebGPU in the browser.
Used by the Audio Split Space. MIT, per the base model.
