How to auto-tune a vocal
- Press Record from microphone and sing a take, or drop in an existing vocal file (MP3, WAV, OGG, M4A).
- Pick the key root note and a scale — Major, Minor or Chromatic — to match the song.
- Set the retune strength: low for transparent pitch correction, full for the hard robotic snap.
- Press the tune button, compare Original and Tuned, then download your corrected vocal.
This auto-tune online tool gives you real pitch correction without installing a DAW or buying a plugin: the pitch tracker finds every note you sang and pulls it toward the nearest note of your chosen scale, with the strength slider deciding whether that pull is a gentle nudge or an instant snap. Singers use it to polish covers and demo takes, rappers chase the melodic robotic sound, and creators tune voice clips for TikTok hooks and YouTube intros. Processing happens locally in the browser — your voice is never uploaded — and every render is free with no watermark.
FAQ
How do I auto-tune my voice online for free?
Record a vocal straight from your microphone or drop in a file, choose the key and scale of your song, set the retune strength, and press the tune button. The corrected take renders in seconds on your device and downloads as MP3 or WAV — no account needed.
How do I get the hard robotic auto-tune effect?
Push the retune strength to maximum. At full strength every note snaps instantly to the scale, which produces the unmistakable robotic glide made famous in hip-hop and pop. For natural-sounding correction, keep the strength low so pitch moves are gentler.
What key and scale should I pick?
Use the key of the song you are singing over — if you are not sure, run the track through the BPM and key detector first. Major suits most pop, minor suits darker songs, and Chromatic snaps to the nearest semitone regardless of key, which works when the key is unknown.
Does this auto-tune work on phones and without uploads?
Yes — it runs in modern mobile and desktop browsers, and the pitch correction is computed entirely on your device. Your vocal is never uploaded, and there are no limits on how many takes you process.
