GEMINI
Doubler KM-22 · free
A second take you didn't have to sing.
GEMINI is a free vocal doubler plugin: it builds a second, slightly different performance from one take and spreads it left and right, for wide hooks and thick backing vocals.
Free for good · macOS · AU · VST3 · In development

What it does.
A double-tracked vocal sounds big because the two takes are never quite the same: timing drifts a little, pitch moves a little. GEMINI builds that second take from one recording, with small shifts in time and pitch that keep changing, so it never sounds like a copy.
Width spreads the double left and right; Blend sets how loud it sits against the original. Mono-safe: fold it to mono and the voice does not hollow out.
- Hooks
- Backing vocals
- Ad-libs
- Guitars
- Tightness
- How far the double drifts from the original, from a tight overdub to a loose second singer.
- Width and Blend
- Width places the double from center to wide; Blend sets its level against the original.
- Mono-safe
- The double is built so the mix still holds when it is played on one speaker.
GEMINI is almost ready.
