Overview
UVR is a Tkinter desktop app that separates audio files into vocal and instrumental stems. It uses models trained by its core developers (MDX-Net, MDX23C, VR) plus Demucs v3/v4 4-stem models. Windows and macOS installers bundle Python and PyTorch, while Linux runs from source. It also includes Time Stretch and Pitch Shift tools that use Rubber Band.
Who it is for: Musicians and audio editors extracting vocals or stems locally
Strengths
- Windows and macOS installers bundle Python and PyTorch, so no prerequisites
- Supports MDX-Net, MDX23C, Demucs v4 and VR architectures in one interface
- MPS acceleration on Apple M1 for Demucs v4 and all MDX-Net models
- MIT-licensed code; settings are remembered between sessions
Weaknesses
- Last tagged release is v5.6 from September 2023; updates are tracked in a GitHub issue
- Windows install must be on the C: drive; other drives cause instability
- AMD GPU support is limited, via a separate branch or a DirectML beta build
- Linux has no installer; needs manual venv setup and running UVR.py
What it needs
- GPU optional
- Needs FFmpeg, Rubber Band, PyTorch, Python 3.9 (Windows manual install)
- Models: MDX-Net, MDX23C, Demucs v3, Demucs v4, VR Architecture
