Extract the acapella from a song
Isolate the voice: upload a song and get the vocals alone, without drums, bass or instruments, for remixes, mash-ups, sampling, vocal practice or transcription.
How it works
- Choose a song (up to 500 MB and 10 minutes).
- Pick MP3 or WAV; WAV is the better choice for remixing.
- Play the acapella in the page or download it. Deleted after 60 minutes.
Questions
Why is there a little music left?
Sounds that overlap the voice in pitch and timing (a strummed guitar, a synth pad, reverb from the mix) can leak into the vocal track at a low level. A cleaner, higher-bitrate source gives a cleaner acapella.
Can I get the lyrics as text?
Yes: upload the acapella to txscribe.ai; a voice without the music around it transcribes more accurately than the full mix.
How clean is the separation?
Good on most studio recordings, but not perfect: reverb tails, backing vocals and instruments that sit in the vocal range (a lead guitar, a sax) can leave traces in the wrong track, and heavily compressed or low-bitrate files separate less cleanly. Upload the best-quality copy you have.
What happens to my file?
It is uploaded to our server, separated there, and the upload and every result are deleted automatically 60 minutes after the job started. Nothing is kept, nothing is used to train anything, and nobody listens to it.
What are the limits?
Files up to 500 MB and 10 minutes long. One song is separated at a time, so at busy moments yours waits in a short queue; the page shows how many are ahead.
Which model does the separating?
Hybrid Transformer Demucs (htdemucs), the open-source music source separation model published by Meta AI researchers under the MIT licence. It runs on our own servers; your audio is not sent to any other service.
May I use the result?
The separated tracks are still the song. Use them the way you are allowed to use the original: practice, study, remixes for yourself, or material you own or have licensed.
Do I need an account?
No. There is nothing to sign up for and nothing to install.
