Auto-Tune Online with Professional AI Pitch Correction

Get studio-grade vocal polish fast. Our AI Pitch Correction analyzes your vocal pitch over time, detects drift, and applies a smooth correction curve that keeps your performance human — but reliably in key.

Built for creators searching Auto-Tune Online, pitch correction online, and AI pitch correction. Use it for lead vocals, harmonies, doubles, hooks, and vocal stacks — with controls that let you choose “natural polish” or the modern hard-tune sound.

Smooth time-varying tuning (no choppy stepping)
Formant-aware pitch shifting to preserve tone

Neural Tuning Intelligence

Accurate pitch tracking is the foundation of great Auto-Tune Online. Our system tracks pitch frame-by-frame, stays stable on real-world recordings, and corrects only what needs correcting — so vocals stay musical, not “wobbly.”

  • Key/Scale targeting: Major, Minor, Harmonic/Melodic Minor, and Chromatic modes.
  • Time-varying correction: tuning glides smoothly instead of jumping between notes.
  • Formant-aware shifting: helps keep your vocal character intact when pitch changes.
  • Safety clamping: prevents extreme jumps that commonly cause artifacts.

This is ideal for vocal pitch correction on rap hooks, melodic trap, pop toplines, and R&B — especially when you need results that sit in the mix without sounding processed.

Modern Studio Control

Dial in exactly how your Auto-Tune Online should behave. Go subtle for realism, or push it for the modern tuned sound — with parameters that match how producers actually work.

  • Strength: from light cleanup to fully locked-in tuning.
  • Retune Speed: slow for natural vocals, fast for hard-tune snap.
  • Humanize: preserves micro-variation and vibrato so it still feels like a performance.
  • Key detection option: choose a key, or let the system estimate it automatically.

Quick starting points

  • Natural vocal tuning: Strength 0.35–0.60, Retune 30–50ms, Humanize 10–20 cents
  • Modern rap / melodic trap: Strength 0.70–1.0, Retune 5–20ms, Humanize 5–12 cents
  • Stacks & doubles: Strength 0.60–0.90, Retune 15–30ms, Humanize 6–14 cents

How Auto-Tune Online Works

1) Analyze pitch

The system tracks the vocal’s fundamental pitch over time and detects which sections are voiced vs unvoiced. That means it can avoid “tuning the noise” in breaths and pauses.

2) Build a correction curve

We compute a smooth correction curve that pulls the vocal toward the chosen scale while preserving performance detail — not just snapping everything to the nearest note.

3) High-quality pitch shift

The tuned vocal is pitch-shifted with quality safeguards designed to reduce warble and protect vocal tone, so your output is ready for mixing.

Frequently Asked Questions

Will it make my vocals sound robotic?
Only if you push it there. Fast retune speeds (roughly 5–20ms) with high strength create the modern hard-tune effect. For natural results, use slower retune (30–50ms) and moderate strength.
Do I need to know my song’s key?
Knowing the key gives the cleanest targeting, but you can also use automatic estimation and then adjust if needed. If your beat changes chords a lot, manual key selection is often best.
What file types can I use for pitch correction online?
Most creators upload WAV for maximum quality, but MP3 and other common formats can work too. If you’re chasing the cleanest tuned vocal, export your raw vocal as WAV and avoid heavy reverb/delay before tuning.
Why do some tools sound warbly or out of tune?
Warble usually comes from weak pitch tracking, tuning unvoiced/noisy sections, or overly aggressive correction. Using moderate settings first, then increasing strength/retune speed, typically gives the cleanest results.
