Duo from Antares Audio Technologies is a plug-in processor that generates a realistic doubled vocal part from an existing vocal. It allows for programming variations in pitch, timing, and vibrato depth in the new doubled vocal.

For added realism, Duo includes adjustable vocal timbre modeling, so you can create a doubled part that sounds like the same person as the lead vocalist—or like someone else entirely. You also have independent control of the level and pan of the original and doubled voices to craft the perfect stereo mix.

Functioning as an Audio Units, AAX Native, or VST3 plug-in for macOS- or Windows-based audio software, Duo makes it possible to instantly create natural-sounding doubling effects for your vocal productions.
