Your audio is never sent anywhere. Everything is processed inside your browser.
Highlights
Create from MP3, WAV, M4A, FLAC, and the audio of video files.
When separation finishes, download the result as WAV straight away.
Everything is processed in-browser, so your song never sits on a server.
Vocals come out while the low and high end keep their feel, for an easy-to-hear backing track.
When to use it
Three simple steps
Drag & drop an MP3, WAV, M4A, FLAC or video, or click to select.
Instant karaoke maker. AI mode can split into 6 parts.
Preview and adjust each part, then download what you need as WAV.
It downloads as WAV. If you need MP3 or another format, convert it with your own editing software.
Yes — vocal extraction uses a lightweight AI model on phones (iPhone/iPad Safari included). AI 6-stem uses a large model, so a PC is recommended.
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.

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.
If vocals + backing track is enough, choose "Vocal extraction"; to split by instrument, choose "AI 6-stem".
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.
Both use the same family of AI model (htdemucs); they differ in how many parts you get. Vocal extraction gives two (vocals and backing track); AI 6-stem gives six (vocals, drums, bass, guitar, piano and other). If you don’t need a specific instrument, vocal extraction is plenty.
Vocal extraction automatically picks between two AI models by device (a high-quality model on PC, a lighter one on phones). Both are genuine AI separation — we never use a low-quality "simple" method. In the rare case neither can load, we ask you to retry on a good connection or a PC.
Please only use audio you own the rights to, or that you are otherwise permitted to use.
