Sometimes(very often!) we need to add effects on our voice recording. To make it sound better, to make it sound thicker, or just to maker it sound incredible!
For widening/thickening, or making choir like voices, you can use : chorus, voice multiplier, voice doubler, stereo wideners.
For radical changes or special FX, you can use harmonizer / pitch changing, genre changer, pitch correction / autotune.

5) ag-works chorus ch-2

Chorus CH-2 VST

Free Vst Plugins Voice Mixtape

Here, at Wavosaur, we love the monstachorus VST by Betabugs, but i thought the Chorus CH-2 is lesser known, and deserve some exposure. It’s like having 4 independant chorus you can tweak in parallel.
