How to separate vocals online (browser workflow)

Upload → split → preview → optional master → WAV

The browser chain

How to separate vocals online, in practice: open www.1momirr.com, upload a finished song, wait for the split, preview the lead against the accompaniment, optionally run one-click mastering, then download WAV and lyrics. No desktop install.

魔镜音频 (MoJing Audio) aims to pull the lead while keeping backing-vocal depth in the accompaniment. That is a different target from a karaoke mute. If the chorus backing disappears, the job failed even if the lead is quiet.

Do this in order

Upload a mix with a clear chorus. Wait until processing finishes before you refresh. Preview on headphones: breaths on the lead, harmonies on the bed. If you need a release-loud bounce, enable mastering last—not first.

Keep the original file. Artifacts from overlapping spectra are normal; change the source before you chase a stronger split. For accompaniment-first checks, read How to keep accompaniment when removing vocals. For the Chinese lead-split page, see 人声分离.

What the browser cannot promise

A stereo master will not become a studio stem pack. Clipped sources stay clipped. Long reverbs smear. Say the ceiling out loud so the preview has a standard.

When you already have a DAW session, mute and bounce. Use the online workflow when the mix is all you have.

What do I download?

Preview in the browser, then download WAV audio and lyrics. Prefer WAV for any further mix or master; avoid repeated lossy encodes.

Do I need an app?

No. The www.1momirr.com workflow is browser-only for this page.
