What you get

How it works

  1. Open the upload page, pick a local audio or video file, or paste a Bilibili / Douyin link
  2. Submit the task — the server separates it and you can follow the progress on the Tasks page (usually under 5 minutes)
  3. Preview and download the instrumental; use Advanced mix if you want to change the volume of each stem

FAQ

Is extracting the accompaniment free?

Yes, it is completely free and no account is required. If you sign up or sign in later, the tasks you created as a guest are merged into your account automatically.

Will there be vocal bleed left in the instrumental?

Separation uses AI source separation, which removes vocals cleanly for most pop songs. When instruments and vocals overlap heavily (backing vocals, choirs) a little vocal may remain — use Advanced mix to lower the vocal stem further.

Can it process the audio of a video file?

Yes. The audio track is extracted first, then separated, and an extra MP4 with the instrumental replacing the original audio is generated for you.
