SnapTune is an open-source, free real-time pitch correction plugin for vocals, built with JUCE: VST3 and Audio Unit on macOS (Apple Silicon and Intel), VST3 on Windows, and VST3 plus LV2 on Linux. Retune Speed runs from an instant hard-tune snap to slow vibrato-friendly correction, with a formant-preserving Studio mode for mixing and a low-latency Live mode for tracking.

About snaptune

SnapTune is a real-time vocal pitch corrector. Pitch moves without changing the character of the voice, and a separate Formant knob shifts that character on purpose by up to 5 semitones.

Studio mode uses TD-PSOLA at 46 ms latency for formant-safe mixing, while Live mode drops to 2.7 ms so singers can hear themselves tuned during takes. There are 13 scales or custom note sets, MIDI target notes so the voice follows a played melody, and controls for Humanize, Amount, Tracking and Mix. A Voice setting picks the detection range, from Low Male to Soprano or Instrument.

A tuner gauge and a piano-roll pitch graph show what it is doing. Factory presets include Hard Tune, Melodic Trap, Natural and Deep Robot, the code is AGPL-3.0, and the developer puts CPU use under 1 percent.
