On iPhone and iPad, separating may not work: the device can run out of memory and the page reloads. We recommend separating on a computer. Saved MP3 files can be played on any device.
Keep this screen open until it finishes. On a phone, separation stops while the screen is off or another app is open.

Split a band song into vocals, drums, bass, and other
Band Stem Mixer separates a song into 4 parts with AI: vocals, drums, bass, and other (guitar, keys, and everything else). Choose an audio file such as MP3, WAV, or M4A and press “Separate into 4 parts”. Each part gets its own fader with mute (M) and solo (S), and they play back in perfect sync.
Use it to practice in a band: mute your own part and play along with the rest (a “minus one” backing track), solo the bass or the drums to copy a phrase by ear, or turn the vocals off for karaoke. Each part, and the mix you made, can be saved as an MP3 file.
The separation runs in your browser. Your song is not uploaded anywhere. The first time, the app downloads the AI model (about 170 MB; it is kept on your device for next time), so use Wi-Fi. If you are on mobile data, the app asks before downloading. Separation takes a while: about the length of the song or a few times longer on a recent computer, and longer on a phone.
The model is Demucs (htdemucs), a music separation model by Meta. Like all such models it is not perfect: sounds can leak between parts. Guitar and keys are not split from each other; they come out together in “Other”. Free, with no sign-up and no ads.
