Stemina
Stemina splits a music file into six separated stems — bass, drums, other, vocals, guitar
and piano — entirely inside your browser. Your audio is never uploaded.
The separation model runs on your own GPU through WebGPU, and falls back to WebAssembly
where WebGPU is unavailable. Because every stage happens on the device, Stemina needs
JavaScript to run. Please enable JavaScript and reload this page.
What it does
- Accepts MP3, WAV, FLAC, M4A and OGG.
- Produces six stems: bass, drums, other, vocals, guitar and piano.
- Plays them back together, with solo, mute and gain on every lane.
- Cuts regions out of any stem and saves them as samples.
- Exports WAV, MP3 or FLAC, one stem at a time or all of them as a ZIP.
What it needs
A recent desktop browser. WebGPU makes separation several times faster; without it the
WebAssembly path still works, more slowly. The model is about 336 MB and is downloaded
once, then kept on the device.
