AutoTune AUv3
Pitch correction that fits your mix — as a plugin or standalone
What it is
AutoTune AUv3 is an iOS and Mac AUv3 plugin for real-time pitch correction and vocal tuning. It processes incoming audio through a pitch detection and correction engine, letting you dial in everything from subtle natural tuning to the signature hard-tuned effect — all inside your favorite DAW or as a standalone app.
Who it’s for
Vocalists, producers, podcasters, and live performers on iOS and Mac who want transparent pitch correction in AUM, GarageBand, Cubasis, Logic Pro, Loopy Pro, or any AUv3-compatible host.
Features
Real-time pitch correction
Corrects pitch in real time as you sing or play — no offline processing, no latency-compensated warping.
Key & scale selection
Lock correction to a specific key and scale, or use chromatic mode for full flexibility.
Retune speed control
Adjust how quickly the correction kicks in — from subtle natural pitch shaping to instant hard-tuned effect.
Formant preservation
Maintains natural vocal character even with aggressive correction, so tuned vocals don't sound thin or artificial.
Low-latency passthrough
Hear your processed signal in real time with minimal added latency, suitable for both tracking and live use.
Works in any AUv3 host
Runs as an Audio Unit extension on iOS and Mac — Logic Pro, AUM, GarageBand, Cubasis, Loopy Pro, and other compatible hosts.

Natural or aggressive — your call
AutoTune AUv3 gives you continuous control over correction intensity. Dial the retune speed low for transparent pitch shaping that preserves natural vocal phrasing, or crank it for the signature hard-tuned sound. The formant preservation engine keeps the vocal character intact either way.
Key-aware correction
Set the song key and scale, and the detector locks to the closest in-key note. Chromatic mode is also available for atonal material or when you want to let the performer's intended pitch through with only minor adjustments.
Inline or standalone
Like the rest of the AUv3 lineup, AutoTune AUv3 runs inside your host as an Audio Unit extension — drop it on a vocal track in Logic Pro, AUM, GarageBand, Cubasis, or Loopy Pro — or launch it standalone for quick vocal warmups or pitch reference.
