Voice isolation with the vocal out front
The split isolates the lead voice so the vocal stem you export is the performance, alone.
Why this voice isolation page
Voice isolation done privately — your mixes stay on your hardware from check to stem.
The instrumental comes too
Every voice isolation run yields both stems — keep the vocal, archive the backing, reuse either.
No upload, by design
Voice isolation here never ships your unreleased mix to a server; the browser verifies and the desktop app splits.
Waveform-first preview
See and hear the real file before the split — voice isolation starts with knowing the take is right.
DAW-ready output
WAV at the source rate or compact MP3: the voice isolation stems drop straight into any session.
Free, unlimited, local
No credits and no caps — voice isolation costs nothing because your PC does the computing.
How voice isolation works here
Four steps from a finished mix to an isolated voice.
- 1
Drop in the audio
MP3, WAV, M4A or FLAC. The browser decodes it and draws the waveform — the entry point of voice isolation.
- 2
Verify the source
Duration, channels and codec are confirmed locally before the heavy step of voice isolation begins.
- 3
Run the separation
The free Windows app performs voice isolation on your PC: the model lifts the vocal out of the mix.
- 4
Export the vocal stem
Save the isolated voice as WAV or MP3 — the finished voice isolation result, plus the instrumental if you want it.
What voice isolation actually gives you
Stems, bleed and the honest limits of lifting a voice out of a mix.
The vocal stem, defined
Voice isolation renders the lead performance as its own track: what the singer did, separated from what the band did. In a two-stem split, the complement — everything else — is your instrumental.
This is the modern meaning of voice isolation: model-based separation. It replaced mid-side cancellation, which only removed centered content and wrecked the stereo image in the process.
Where voice isolation shines
Acapella creation, remix stems, podcast intros sung over beds, dialogue rescue from mixed camera audio — voice isolation is the tool whenever the voice is the deliverable.
Producers also use voice isolation to study phrasing: hearing the naked vocal teaches more than a hundred listens to the full mix.
Honest limits
Voice isolation separates sources, not tracks: backing vocals may follow the lead, dense reverb can ghost, and heavily clipped masters reduce cleanliness. Expect excellent, not surgical.
Voice isolation also does not transcribe, tune or time-correct — it isolates. What you do with the stem is your craft.
Voice isolation in practice
The recurring jobs where voice isolation pays for itself immediately.
Build acapellas
Voice isolation turns your catalog into acapella stems for live mashups and remix requests.
Rescue interview audio
A presenter miced the room, not the guest — voice isolation lifts the speech from the mixed recording.
Remix prep
Labels send stems late; voice isolation gets the vocal out today so the remix starts now.
Honest limits of voice isolation
What this tool will not pretend to do.
The split runs in the app
Browser steps preview and verify; the model step of voice isolation runs in the free Windows app.
One voice, not speaker ID
Voice isolation isolates the vocal as a source — it does not separate two speakers talking over each other.
Not denoise
Hiss and hum are noise, not another source; pair voice isolation with a denoiser when needed.
Rights stay with the song
Isolating a voice grants no publishing rights — clear your samples as always.
