Pitch Shifter vs Vocal Tuner: What's the Difference?
Both change pitch — but they do it in completely different ways. A pitch shifter moves the whole file by a fixed interval. A vocal tuner snaps individual notes to a scale. Here's when to use which.

Real-world workflows
- Fixing a flat chorus vocal? Vocal Tuner — pick the song key, set retune to ~30 (natural), let it pull each note into the scale.
- Making a slowed-and-reverb edit? Pitch Shifter — drop the song -2 to -4 semitones, then run it through the Slowed + Reverb Editor.
- Want hard auto-tune like T-Pain or Future? Vocal Tuner — set retune to 0 (instant snap), pick a tight scale, sing on key.
- Sampling a record but it's in the wrong key? Pitch Shifter — match it to your project key in one move.
Frequently Asked Questions
What is the difference between a pitch shifter and a vocal tuner?
A pitch shifter moves the entire audio file up or down by a fixed amount of semitones — every note shifts by the same interval. A vocal tuner detects each note and snaps it to the nearest pitch in a chosen scale, fixing pitch drift while preserving the melody. Pitch shifter = global transposition. Vocal tuner = per-note correction.
Which one should I use to fix off-key vocals?
Vocal tuner. A pitch shifter moves a flat note flat by the same amount in the new key — it doesn't fix the underlying pitch error. A vocal tuner detects the note and pulls it to the right pitch in the scale.
Which one should I use to change the key of an entire song?
Pitch shifter. Set semitones to +N or -N to transpose the whole track by that interval. The vocal tuner won't do this — it's a per-note correction tool, not a transposition tool.
Can a pitch shifter create the "T-Pain" / hard auto-tune effect?
No — that effect is created by a vocal tuner with the retune speed cranked all the way up (snap = instant) on a fixed scale. A pitch shifter just transposes — it can't create the snapping effect because there's no per-note detection happening.
Are these as good as Auto-Tune Pro / Melodyne?
For the 90% case — yes. Our free vocal tuner uses the same pitch-detection approach as paid tools (autocorrelation + FFT). Where the paid tools win is in formant preservation at extreme settings, manual note-editing UIs, and undo history. For everyday tuning, our free tool ships radio-ready results.
