Why Notevibes Autotune
Simple, honest, and built to respect your files.
The Full Hard-Tune Sound
Chromatic correction at full strength snaps every note hard to the nearest semitone — the classic hard-tune effect, one click, no settings to learn.
Real Pitch Correction
It tracks the melody and corrects each note individually — not a pitch shifter that moves the whole clip. The voice stays natural, never chipmunked.
Key & Strength in the Editor
Want a gentler, in-key tune instead? The Notevibes AI editor exposes the key, scale, and correction-strength controls — just ask for the sound you want.

Autotune a Vocal Without Installing Anything
The take is almost right. The energy is there, the delivery is there — but a few notes drift, and re-recording never catches the same feel. The usual fix is a DAW pitch plugin, which means an install, a license, and an afternoon of tutorials before a single note moves. This page skips all of that: drop the vocal, the correction runs on our servers, and you download the tuned take — usually in under two minutes.
Hard-tune or natural correction?
Pitch correction comes in two flavors. Cranked to full strength with every semitone allowed, notes snap instantly and you get that unmistakable hard-tuned vocal sound. Dialed back and locked to the song’s key, it turns invisible — the vocal just sounds like a better day in the booth. This page does the first: it runs the same tuning engine as the Notevibes AI editor, locked to chromatic correction at full strength — the instant hard-tune. For the gentler, key-aware version — pick the key, choose major or minor, and set how hard the correction pulls — open the AI editor.
Free, private, and honest about the limits
No watermark, no preview-then-pay wall, no account. Your vocal uploads over an encrypted connection, is processed on our own servers, and both the upload and the result are deleted automatically the moment processing ends — even if it fails. The only limits are fair-use ones that keep the tool free for everyone: a few files per minute, up to 40 MB each.
Tips for the cleanest tune
Record dry — reverb and delay smear the pitch tracking, so add effects after tuning, not before. Keep it to one voice at a time: the tracker follows a single melody, and stacked harmonies or a full mixed song will confuse it. To tune the vocal inside a finished song, first pull the acapella with the vocal remover, autotune that, then lay it back over the instrumental. Not sure what key your song is in before you tune in the editor? The BPM & key detector will tell you. And if you’re after character rather than correction, the voice changer is the tool for that job — then finish the whole track in the online audio editor.
Want to Pick the Key, Scale, and Strength?
The Notevibes AI editor autotunes to a specific key and scale, lets you dial the correction strength from subtle to full hard-tune, and finishes the mix — trim, fades, cleanup, export — all by chatting.

Online Autotune FAQ
How does the online autotune work?
Upload a vocal and pitch correction runs on our own Google Cloud servers: the AI tracks the melody, then pulls each note to the nearest in-tune pitch while keeping the voice natural. The tuned take is usually ready in under two minutes and downloads as a WAV.
Is the online autotune free?
Yes — no sign-up, no watermark, no preview wall. To keep it free for everyone there is a fair-use limit of a few files per minute, and uploads are capped at 40 MB.
Will it give me the full hard-tune effect?
Yes. This page runs chromatic correction at full strength — every note snaps hard to the nearest semitone, which is exactly the classic hard-tune effect. No settings needed.
Can I choose the key, scale, or correction strength?
Those controls live in the Notevibes AI editor: tune to a specific key, choose major or minor, and set how strongly notes are pulled for a gentler, more natural correction. This page stays one-click with the hard-tune default.
What should I upload?
A solo vocal or clearly voiced take works best — the pitch tracker follows one voice. A full mixed song is not what it's for: pull the acapella with the vocal remover first, autotune that, then lay it back over the instrumental.
What format is the result?
The tuned vocal downloads as an uncompressed WAV, whatever you upload — MP3, WAV, M4A, FLAC, and other common audio formats up to 40 MB all work.
What happens to my file?
It is uploaded over an encrypted connection, processed on our own Google Cloud servers, and both the upload and the tuned result are deleted automatically right after processing — even if the tune fails. Nothing is stored, shared, or used for training.
