see the main project: https://github.com/bohning/usdb_syncer

This repository is a separation provider. It allows performing stem separation on audio (with optional CUDA acceleration).

Build

1. uv is required

2. With CUDA 12.8 / RTX 5070 Ti support: uv run --extra cuda128 pyinstaller -n usdb_syncer_separation_cuda --collect-data demucs run.py

3. CPU-only: uv run --extra cpu pyinstaller -n usdb_syncer_separation_cpu --collect-data demucs run.py

4. The resulting binary will be in dist/usdb_syncer_separation_cuda or dist/usdb_syncer_separation_cpu, respectively. You can copy it to a location of your choice (make sure to copy the _internal folder as well) and point the Syncer to it.
