Split a song into separate stems — vocals, drums, bass and the rest — using AI.
Your stems are in this browser now — play them above and download any of them as MP3, FLAC or WAV. We keep no copy on our servers. They live in this tab only, so download the ones you want before you close or reload the page.
Want just the instrumental or just the vocal? The Vocal Remover and Vocal Extractor do exactly that in one click. To re-encode a stem or change its sample rate, use the Format Converter.
A stem separator takes a finished, mixed song and pulls it back apart into its stems — the isolated vocals, drums, bass and other instruments. It is the closest thing there is to un-baking a cake: an AI model trained on thousands of songs estimates what each part sounded like on its own. The result is not a perfect studio multitrack, but it is good enough for karaoke, remixing, practice, sampling and transcription.
Unlike the other tools here, this one runs on our servers, not in your browser — the models are far too large and too slow to run on a phone or laptop. So it needs an upload, and it takes longer than an instant local conversion. Everything else on the site still runs entirely on your device.
| Choice | You get | Best for |
|---|---|---|
| 2 stems | Vocals, and everything else as one backing track | Karaoke and instrumentals — the fastest option. |
| 4 stems | Vocals, drums, bass and other, separately | Remixing and practice, when you need the parts apart. |
| 4 stems, best | The same four, from a higher-quality model | Cleaner separation when you can wait a little longer. |
If you only want the instrumental or only the vocal, the Vocal Remover and Vocal Extractor are the same engine with the choice made for you.
MP3 is smaller and plays everywhere — right for sharing a karaoke track or dropping a stem into a video. FLAC is lossless and about half the size of WAV — right when a stem is going back into a mix, where you do not want to stack another lossy step on top of the separation. WAV is lossless and uncompressed, the plainest thing to drop onto a DAW track. The stems come back lossless and the format is made in your browser, so switching it never re-runs the separation — and you can still re-encode later with the Format Converter.
