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?
Works from live voice or a file you already have
Snaps pitch to musical notes — not just a key transpose
Free 320 kbps MP3, no account
Pairs with the key changer if you only need to shift the whole song
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.
