Highlights
Splits into vocals, drums, bass, guitar, piano and other, with guitar exportable on its own.

When to use it
Three simple steps
Drag & drop an MP3, WAV, M4A, FLAC or video, or click to select.
Standard is enough for guitar extractor. Choose 4stem or 6stem to split the instruments out.
Preview and adjust each part, then download what you need as WAV.
6stem. It is the only one that treats guitar as its own part — in 4stem the guitar is folded into "other".
Both are handled. Heavily distorted guitar, and parts whose timbre is close to a synth, can bleed into "other" — results vary by track.
Not just vocals and backing — pull out drums, bass, guitar and piano on their own.
No account, no install. Just open the page and choose a file.
Remove vocals to make a backing track, or isolate just the vocals. Great prep for practice or production.
Try each part’s volume and mute right there, then save only what you need as WAV.
It means automatically splitting one song into six parts. Here is what each one is:
Drag & drop an MP3, WAV, M4A, FLAC or video, or click to select.
Not sure? Take Standard, the recommended one. In a hurry, take Fast; to split by instrument, take 4stem or 6stem.
Play and adjust each part, then save just what you need as WAV.
It’s completely free with no account needed. Just open the page and pick a file.
No. All separation happens entirely inside your browser.
MP3, WAV, M4A, AAC, FLAC and OGG, plus the audio track of video files.
If you are unsure, take Standard — the one marked Recommended. Pick Fast when speed matters most, 4stem or 6stem to split out drums, bass and the rest, or High Quality when you want the best result and can wait. Every card shows what comes back and roughly how long it takes.
It depends on the model and your device. Fast handles a 3-minute song in well under a minute; Standard takes a few minutes. Each card shows an estimate for your device before you start, and you can keep working in other tabs meanwhile.
Yes. On iPhone and Android, Fast splits vocals from the backing track. Models that need more memory than your device has are shown as unavailable, with the reason.
