# HTDemucs — CoreML

Meta's [HTDemucs](https://github.com/facebookresearch/demucs) (Hybrid Transformer Demucs) vocal /
instrumental separator, converted to CoreML. `HTDemucsSpec.mlmodelc.zip` is the compiled model
used by the Kioku iOS app to isolate vocals before on-device lyric alignment.

## License

Demucs is released by Meta under the **MIT** license; this conversion carries the same license.
