Turn any voice into a choir.
VST/AU plugin for Mac & Windows
One vocalist goes in. A bunch come out.
Record a take. autochoir sings it back with a choir.
They’re not copies of your voice. This is not a chorus plugin. Every singer has their own voice model, pitch and timing, so it sounds like a real choir. You can add new voices with our free packs, or even add yourself by training a singer on your own vocals with just a couple clicks.
And the choir is yours to arrange. Place each singer on the stage, then set the panning of each section, the formant of each row, or a single singer’s octave.

Make your own voices.
The pack maker turns a few minutes of someone singing into a new singer you can use and share. Add the recordings, press train, drop it in the plugin. It’s really that easy.
Your voice, a friend’s, a session singer’s. It all trains on your own computer, and it comes with autochoir2.
Works offline.
Nothing you record leaves your machine. No upload, no account, no waiting on a server.
Know your voices.
We train every singer ourselves, and the plugin says where each one came from. Or train your own.
Pay once.
Every 2.x update included. No subscription, and nothing to renew.

the old plugin
autochoir legacy is not a free trial of autochoir2.
It’s our first plugin, and we still give it away. It runs an older, different algorithm with seven singers and few controls, and it sounds rougher and more robotic than autochoir2. Please don’t judge autochoir2 by it.
