StemRoller is a free open-source desktop app that separates vocals, drums, bass, and other stems from any song with a single click, using Facebook's Demucs deep-learning model and YouTube search integration. It is built with Electron and Svelte and bundles everything needed for stem splitting.
Use cases
- make karaoke instrumental tracks from any song
- extract acapella vocals from a track
- split a song into vocals, drums, bass, and other stems
- create instrumental versions of songs for DJing or remixing
- download a song from YouTube and separate its stems automatically
When to choose
- you want a simple one-click GUI for AI stem separation without using the command line
- you need free, open-source vocal/instrumental isolation for karaoke or remixing
- you want search-and-split workflow that fetches songs from YouTube for you
When to avoid
- you need real-time or low-latency stem separation
- you need fine-grained control over the Demucs model or batch processing pipelines
- you need a supported Linux build - Linux is not officially supported
- you need more than four stems or custom separation models
