How to autotune your voice

1

Record or upload

Use Live voice to capture the mic, or upload an MP3/WAV of a vocal take.

2

Choose style and scale

Hard snaps notes quickly. Natural is smoother. Pick chromatic, major, minor, or pentatonic and a key.

3

Download the MP3

Pitch is detected (YIN) and retuned with overlap-add. The file downloads automatically when ready.

What is this autotune?

This is real pitch correction, not only a chorus effect. The engine estimates the sung note, snaps it to the nearest scale degree, and time-shifts each grain so the melody sits in tune. Hard style is the familiar radio/T-Pain sound. Natural keeps more of your original slides.

What you can do

Live microphone

Record in the browser, then autotune the take. No extra app.

Upload a file

Drop a vocal MP3, WAV, M4A, or WebM and correct it the same way.

Hard or natural

Hard locks notes tightly. Natural eases the correction.

Scale and key

Chromatic, major, minor, or pentatonic in any key from C through B.

Why use this autotune?

Quality and limits

Live takes up to 90 seconds. Uploads up to 3 minutes and 80 MB. Best on a dry vocal; loud music behind the voice can confuse pitch detection. Files are processed then deleted.

Autotune FAQ

Is it free?

Yes. Record or upload, convert, and download without an account. Ads may appear during and after conversion.

Is this real autotune?

Yes. Pitch is measured with YIN and each note is snapped to your scale, then grains are retuned. It is not a studio Antares plugin, but it is true pitch correction rather than a fake chorus.

Can I use my microphone?

Yes. Choose Live voice, allow the mic, record, stop, then Autotune. If the browser blocks the mic, upload a file instead.

Hard vs natural?

Hard is the robotic, locked-note sound. Natural still corrects pitch but follows your slides more.

Which scale should I pick?

If you are unsure, use Chromatic. If you know the song is in C major, pick Major and key C.

Does it work on a full mix?

It works best on a solo vocal. A full song with drums and bass can hide the melody.

Is my recording stored?

No. It is processed then deleted from the server.

Why did autotune fail?

The take may be too quiet, too short, too long, or mostly noise. Record closer to the mic or upload a clearer vocal.
