Graillon 2

Graillon 2, by Auburn Sounds, is a free real-time vocal pitch-correction and voice-changing plugin — the closest free alternative to something like Auto-Tune. Drop it on a vocal track, set a key, and it snaps the pitch automatically, or dial it back for a subtle, more natural correction. It also works as a straightforward pitch shifter, so it doubles as a quick way to make a voice sound more masculine or feminine, or to transpose any monophonic source.

Features

• Automatic real-time pitch correction with adjustable snap range, smoothing speed, and inertia — from a subtle nudge to the obvious “robotic” tuned effect.
• Pitch shifter with a Preserve Formants control, so shifted voices don’t lose their natural character.
• MIDI input support for note-by-note pitch correction with more precise control over the melody.
• Built-in presets to get started quickly, plus the ability to save your own.

The free edition unlocks the Pitch Shifter and Pitch Correction modules — the two core functions — while the paid full version (around €29) adds extras like a bit crusher and pitch-tracking modulation.

Compatibility

Free. Available in VST / VST3 / AU, for Windows & macOS, 32 and 64-bit.
