A Python package and CLI that separates audio files into stems (vocals, instrumental, drums, bass, etc.) using pre-trained models from Ultimate Vocal Remover such as MDX-Net, VR Arch, Demucs, and MDXC. It supports GPU acceleration via CUDA, CoreML, and DirectML, and can also perform denoising and reverb removal.

Use cases

• separate vocals from instrumental in a song
• make karaoke tracks from mp3 files
• split a song into drums bass and guitar stems
• remove reverb or echo from audio recordings
• batch separate audio stems from the command line
• integrate stem separation into a python app

When to choose

• you need vocal/instrumental separation with a simple CLI or Python API
• you want access to many UVR pre-trained models without building a GUI
• you have a CUDA GPU, Apple Silicon, or want CPU fallback
• you are producing karaoke videos or remixing stems

When to avoid

• you need a graphical interface for stem separation (use UVR directly)
• you need real-time live audio separation
• you want general-purpose audio editing beyond stem separation
