Online Stem Splitter
Drop a song. Get the vocals and the instrumental as separate stems you can mute, solo, and mix right here. The AI runs in your browser on your own graphics card, so nothing is uploaded. Four stems (vocals, drums, bass, instruments) and full-length files are free in the desktop app.

The in-browser splitter needs WebGPU (Chrome, Edge, Brave, Arc, or Opera on a computer). Two ways to split stems right now, both free and both on-device:
Two free splits here. The app does the rest.
Preview downloads here are the first 60 seconds. Xport Studio splits unlimited songs into four full-length WAVs (vocals, drums, bass, instruments) with a choice of separation models, including BS-Roformer. Offline, free forever.
Full-length stems live in the app
Your 60-second preview is downloading. For the whole song, Xport Studio does it free, offline, with no limits:
- Four stems: vocals, drums, bass, instruments, as full-length WAVs. Or just the acapella, or just the instrumental.
- Multiple separation models to choose from, including MDX-Net and BS-Roformer (the current state of the art), not just the one this page runs.
- Unlimited tracks, batch splitting, GPU-fast. Free forever, no subscription.
- Nothing uploaded, ever. Same rule as here.

How stem separation works here
A source-separation model listens to the mix and predicts what belongs to the voice, the drums, the bass, and everything else. Normally that model runs on a company's servers, which is why every other online stem splitter starts with an upload. This one runs on your graphics card through WebGPU, inside the browser tab. The song is decoded, split, and mixed back without ever leaving your machine.
What's free here, and what's in the app
Your first two splits on this page are free: mute the vocals for a karaoke pass, solo the vocal to study a take, download a 60-second preview of either stem. This page runs one model (UVR-MDX-NET) and gives two stems. The Xport Studio desktop app is where it gets serious: unlimited songs, four stems (vocals, drums, bass, instruments) or just the acapella or instrumental, full-length WAVs, batch splitting, and a choice of separation models including BS-Roformer, the current state of the art. It runs offline on Mac and Windows and is free forever. We'd rather you use the app for the heavy lifting than make you wait on a browser tab.
Tips for cleaner stems
Lossless or high-bitrate sources (WAV, FLAC, 320 kbps MP3) separate better than low-bitrate files. Heavily compressed masters bleed more between drums and bass. If vocals leak into the instruments stem, that is the model hearing doubled or heavily effected vocals as "other"; the app's higher-quality mode handles those cases better.
