Free online vocal pitch correction & cleanup

Record a vocal or a single-note melody, press Vocal Editor, and see every note drawn on a piano roll. Drag a note to retune it, snap the whole take to a key, then clean up noise, breaths and harsh S sounds, all before you apply anything.

Free with a quick email sign-up. Nothing changes in your recording until you press Apply to Track, and Ctrl+Z undoes it afterwards.
Quick start

Fix a vocal in four steps

  1. Record onto a track

    Record your vocal, or any single-note melody such as a solo, a whistle or a bass line, onto a track in the recorder. It works best on one voice or one instrument at a time.

  2. Open the Vocal Editor and Analyze

    Press Vocal Editor in that track's second row, then Analyze. Fretnook finds each sung note and draws it on a piano roll.

  3. Retune

    Drag a note up or down to retune it. It snaps to whole semitones; hold Shift for fine control. Or choose a Key and Scale and press Snap All to Key, and set Strength to decide how far each note is pulled.

  4. Preview and apply

    Use Preview to hear the result and Original to compare, then Apply to Track to commit it.

What you get

Pitch tools and voice cleanup in one editor

Note-by-note pitch editing

Every detected note appears on a piano roll. Drag, or use the plus and minus one semitone and ten cent buttons.

Snap to a key

Choose a key and scale and pull every note to the nearest scale note. Strength below 100% keeps some human wobble.

Snap to nearest semitone

Fix out-of-tune notes without choosing a scale. Flatten Drift smooths slow pitch wandering inside a held note.

Formant control

Retuned notes keep their natural tone, or you can move the formant on its own for a deeper, bigger voice or a lighter, smaller one.

Live auto-tune

A real-time version that runs as the track plays and in exports, with Amount, Key, Scale and Speed. Instant speed gives the hard robotic effect.

Voice cleanup

Reduce Noise, Reduce Breaths and a De-esser, plus an Apply Vocal Preset button that sets a sensible starting point.

Natural correction or the classic effect

For a natural result, use a moderate Strength and a slower Speed, or move only the notes that are clearly off. Fully snapping every note to a key at 100% gives a tighter, more processed sound, and instant speed in the live auto-tune gives the well-known robotic effect. Both are available, and Preview lets you compare before committing.

The live auto-tune is quicker but rougher than the note editor. For a polished vocal, do the note-by-note edit and use the live version for effect.

Cleaning up the recording

Reduce Noise learns the background hiss from the quietest parts of the take and removes it. Reduce Breaths turns down the gaps between phrases where a breath is louder than it should be. Both rewrite the recording, and Ctrl+Z undoes them.

The De-esser softens harsh S sounds and works as a live mixer setting, as does Apply Vocal Preset, which adds a low-cut, mud cut, presence lift, compression, de-esser and a touch of reverb. You can fine-tune all of them in the mixer.

What it works best on

Pitch correction works on a single melody line, one note at a time. A solo vocal or a lead instrument gives good results. A full chord strummed on guitar is not a good fit, so use it on single-note parts. For chords, the Ear Trainer's Chord ID is the right tool.

Questions

Frequently asked questions

Is this pitch correction tool free?
Yes. The Vocal Editor is part of the DAW, which unlocks with a free email sign-up.
Will it change my original recording?
Not until you press Apply to Track, and you can undo it afterwards with Ctrl+Z (Cmd+Z on a Mac). Noise and breath reduction also rewrite the recording and can be undone the same way.
Does it work on guitar?
It works on single-note melodies, so lead lines and bass lines can be tuned. It is not designed for strummed chords.
Will it make a voice sound robotic?
Only if you want that. Lower Strength and slower Speed keep the correction natural; instant speed gives the classic hard effect.
Is my voice uploaded?
No. Recording and editing happen in your browser on your own device.
