Experimental monophonic vocal tuner. May produce artifacts; not equivalent to a studio tuner.
Engines and licensesAbout Vocal Tuner
Vocal Tuner detects the note you sing and moves it to the nearest note in the key and scale you choose, like studio autotune. Instant correction gives you the robotic T-Pain sound; slow correction gives an almost invisible touch-up. Record your voice with the microphone or upload a recording, and compare before and after. It's an experimental tuner for a single voice with no backing music.
What you can do with it
- 01
The robotic effect
Set the retune speed to zero: each note snaps straight to the next, with the unmistakable trap and R&B sound.
- 02
Polish demos and covers
With gentle correction in the song's scale, stray notes get straightened without losing your natural voice.
- 03
Before-and-after videos
Record a raw take and compare it with the tuned one: the contrast works great on social media.
- 04
Practice your pitch
The note display shows which note you sing and which one it's corrected to, so you know if you're sharp or flat.

The presets
Robotic
Snaps instantly to every semitone of the chromatic scale: the most extreme effect.
Dark trap
Minor pentatonic with very heavy correction, all over today's trap and rap.
The ’98 effect
The hard snap that made autotune famous in late-nineties pop.
Pop
Clear but controlled correction, like today's pop productions.
Subtle polish
A barely noticeable adjustment that only straightens the notes that are off.
Custom
You choose the key, scale (8 available), retune speed and mix with the original voice.
Tips for better results
- Experimental monophonic vocal tuner. May produce artifacts; not equivalent to a studio tuner.
- If you don't know the song's key, start with the chromatic scale: it corrects to the nearest note, whatever it is.
- The wrong key forces big corrections and makes the voice sound metallic; check it with BPM Detector.
- For a more musical robotic effect, try the minor pentatonic scale.
- It works best with the voice alone: if your recording has music, separate it first with Vocal Remover.
- With the mix below 100% you blend original and tuned voice for a more natural result.
Frequently asked questions
How do I get the T-Pain effect?
Choose the Robotic preset or set the retune speed to zero. The voice will jump from note to note with no transitions; the chromatic or minor pentatonic scale makes it stronger.
Which key should I choose?
The key of the song you're singing over. If you don't know it, use the chromatic scale, which works with any song, or find it with BPM Detector.
What does retune speed do?
It sets how quickly the voice reaches the correct note. At zero the jump is instant and robotic; the higher you set it, the more natural vibrato and slides are kept.
What is the mix for?
It blends your original voice with the tuned one. At 100% you only hear the tuned voice; at 0%, the original; in between, a mix of both.
Why does my voice sound metallic?
Usually because the key doesn't fit, the corrections are very large or there's background noise. Check the key, raise the retune speed a little and record somewhere quiet.
Is it the same as a studio tuner?
Not quite: it's an experimental tuner for monophonic vocals and can produce artifacts. For demos, videos and effects it works really well.
