Online pitch correction: fix off-key vocals note by note
To fix an off-key vocal online, open it in IchiPitchy's pitch editor. Every sung note appears as an editable block on a piano roll: drag a block to correct its pitch, or double-click it to reshape the pitch curve inside the note with control points. Nothing is installed and the export is lossless WAV.
Note-level, not track-level
Blanket correction across a whole track fixes the wrong problem: it flattens the notes that were already fine along with the ones that were not. Working note by note means you can pull one flat word into tune and leave the rest of the phrase untouched.
Notes are detected automatically on import, so you start from a piano roll that already matches your performance instead of drawing it yourself.
Pitch curves, not just pitch
A sung note is not one pitch — it slides in, drifts and often ends with vibrato. Double-clicking a note opens its pitch curve, where control points let you straighten drift, tame or deepen vibrato, and reshape the approach into the note.
The cut tool splits one detected block into separate segments when two words were captured as a single note, and segments can be merged back together.
Correct by hand, or start automatically
Automatic correction to a detected key and scale gets a take most of the way there in one move, with a Level control for correction strength and Smooth for how much natural movement survives. Manual editing then handles whatever is left.
Denoise plus per-note or global effects — gain, EQ, compressor, reverb and delay — are available in the same editor, so a corrected take can be finished without leaving the page.
When to correct, and when to leave it alone
Not every deviation is an error. Vibrato, scoops into a note and slight sharpness on a climactic line are expressive devices — flattening them is the difference between a tuned vocal and a lifeless one. The useful question is whether a note reads as a wrong note or as a choice.
A practical order of work: fix clearly wrong notes first, listen to the whole phrase again, and only then decide whether anything else needs touching. Most takes need far fewer corrections than they appear to on first listen.
Recording a vocal that is easy to tune
- Detection needs a clean signal. Room noise, headphone bleed and heavy compression all make note boundaries harder to find.
- Aim for peaks around −12 to −6 dBFS. A quiet take forces gain later; a clipped take is unrecoverable.
- Sing to a reference — a piano or backing track — so the pitch centre is consistent across the take.
- One vocal per track. Doubles and harmonies on the same track cannot be separated into individual notes.
- Get the tuning close on the way in. Correction is a repair, not a substitute for a good take.
Pitch-correction approaches compared
| Approach | What it fixes | Keeps the performance intact | Available here |
|---|---|---|---|
| Automatic key/scale snapping | Everything at once | Partly — depends on strength | Yes, Level + Smooth |
| Note-by-note dragging | One wrong note | Yes — untouched notes stay untouched | Yes, piano roll |
| Pitch-curve editing | Drift, scooping, vibrato shape | Yes, most precise | Yes, control points |
| Re-recording the take | Everything | No, it is a new performance | Yes, built-in recorder |
Frequently asked questions
Can I fix just one bad note in a good take?
Yes. That is the point of note-level editing — select the single note block and correct it while the rest of the performance stays exactly as sung.
Does pitch correction make the vocal sound robotic?
Only if you want it to. Light correction with Smooth turned up keeps vibrato and sounds natural; maximum correction with Smooth down gives the deliberately robotic sound.
Is it free?
Yes, completely. Pitch detection, correction, note editing and lossless export are all free, with no subscription and no feature held back behind a payment.
What quality does it export?
Lossless WAV. The final render is done at full quality rather than captured from the live preview.
How many cents off is actually noticeable?
Most listeners begin to hear a sung note as off around 15–20 cents; under about 5 cents it is inaudible. Perfect tuning is not the target — consistency across the phrase matters more.
Should I correct vibrato?
Usually not. Vibrato is expressive, and flattening it is the most common way a corrected vocal ends up sounding worse than the original. If it is too wide or uneven, reshape it on the pitch curve rather than removing it.
What is the difference between pitch correction and autotune?
They are the same operation applied differently. Auto-tune snaps everything to a scale automatically; pitch correction usually means fixing specific notes by hand. Both are available here, and they combine.
Can it fix a note that was sung as the wrong note entirely?
Yes — drag the note block to the pitch you meant. It is a large move rather than a nudge, so expect the result to sound more processed than a small correction.
