What is Graillon 3 Free Edition?
Graillon 3 is a live voice changer and pitch correction plug-in from Auburn Sounds. The maker offers it for Windows, macOS and Linux in VST, AAX, AU and LV2 formats.
There is a Free Edition and a Full Edition, which the maker lists at $29. The free version still offers the basics: pitch shifting, formant shifting and pitch correction.
Pitch correction supports both hard-tune and natural sounds, with three pitch engines (G2, G3 and I1) to choose from. Built-in effects include a compressor, gate, chorus, preamp and bitcrusher, all tuned for vocals.
The Full Edition adds Pitch-Tracking Modulation (PTM), keyboard tuning and a vocal doubler.
Pitch and formant shifting
Voice pitch and timbre (formants) can be shifted separately. You may try it to change a voice's character or build character voices.
Hard-tune to natural correction
The maker says it supports both hard-tune and natural sounds. Its example uses Snap Min, Snap Max, Smooth and Amount for subtle, unobtrusive correction.
Three pitch engines
Choose G2 (keeps the Graillon 2 sound), G3 (updated sound) or I1 (the engine from Inner Pitch). You can switch and compare per voice or song.
Built-in effects
It includes a compressor, gate, chorus, preamp and bitcrusher, all tuned for vocals and adding no latency. Handy when you want to finish voice processing in one plug-in.
Full Edition extras
The Full Edition adds PTM for grit, keyboard tuning beyond equal temperament, and a doubler to help voices sit in a mix. You may start with the free edition and consider the full one if needed.
Wide platform and format support
It covers Windows, macOS and Linux in VST, AAX, AU and LV2. It may be usable across streaming and DAW setups.
