| `htdemucs.mlpackage.zip` | Vocal / accompaniment separation | [Hybrid Transformer Demucs](https://github.com/facebookresearch/demucs) by Meta AI; Core ML conversion from [slaughters85j/htdemucs-coreml](https://huggingface.co/slaughters85j/htdemucs-coreml) | MIT |

The wav2vec2 models were converted to Core ML (English FP16, Korean FP32 because the XLS-R model overflows in FP16; fixed 34-second input at 16 kHz, log-softmax output every 20 ms) without retraining.
`models.json` lists each file's size and SHA-256.
