What kind of product is it?
The official site describes Graillon 3 as “an enhanced pitch correction tool”. It is also introduced as a live voice changer, and is said to cover everything from ordinary vocal sound design to heavily characterful vocal processing. The page also provides an official intro video, a Cheat Sheet and a user guide.
Features (per the manufacturer)
- Pitch shifter: Raises and lowers the pitch of the voice.
- Formant shift: Moves the component that defines the “quality” of a voice (the formant), so you can make the voice thicker or thinner.
- Pitch correction: Supports effects from a “hard tune” style that snaps the pitch clearly into place to a natural-sounding one.
- 3 pitch engines: You can choose from G2 (the sound of Graillon 2), G3 (a newly revised sound) and I1 (the engine from the company’s Inner Pitch).
- Built-in effects: Compressor, gate, chorus, preamp and bitcrusher. They are tuned for vocals, and are described as adding no latency (delay) and being light on resources.
Features in the full edition
The official site says the following 3 features are added in the Full Edition. If you are unsure whether something is in the free edition, use these 3 as a guide.
- Pitch Tracking Modulation (PTM): a function that adds a rough texture in step with the pitch of the voice
- Keyboard tuning: a function that can also match scales other than equal temperament
- Vocal doubler: a function that layers the voice so it blends into the mix
Who it suits
- People who want to try vocal pitch correction for free.
- People who want to change the pitch and formants of a singing voice to make character voices or effect-like voices.
- People interested in using it as a live voice changer, for example for VTubing or streaming.
- People who want a light compressor and gate for vocal tracks handled in a single plug-in as well.
Tips for using it
- For natural correction, it is good to start with a low correction strength and settings that keep the original way of singing.
- Pitch correction tends to land on the intended notes when set to match the key of the song. If you do not know the key, it is safer to check it first.
- The 3 pitch engines may change the feel of the sound even on the same voice. Compare them and choose the one that suits the song.
- Moving the formant a lot tends to sound unnatural, so a common approach is to move it little by little.
- After applying correction, always compare it with the sound before correction.

How to try the free edition
First, prepare a short vocal clip (a few bars) and load Graillon. Pick a few presets, move the strength of the effect and see what changes. Then switch the pitch engines and compare. After that, you should have a rough idea of the settings that suit your voice. Before using it on a whole song, we recommend trying it on the clip alone first.
If you use it as a voice changer, pay attention to the monitor volume and to latency (the time from when you speak until the sound comes back). The official site says the built-in effects do not add latency, but latency also changes with your DAW and audio interface settings.
When using it on a recorded voice, tidying up noise and breath sounds before pitch correction may help the correction work more naturally. In songs with layered vocals, it is also conceivable to correct only the main vocal and give the backing vocals different settings.
