Powered by the same core technology as Antares' professional standard Auto-Tune 7, Auto-Tune EFX 3's new variable Retune Speed and Humanize controls provide an entirely new level of natural, realistic pitch correction. With its unique Auto-Motion Vocal Pattern Generation, stunning new vocal effects are only a mouse click away. Designed to make almost everything automatic, Auto-Tune EFX 3 is the most affordable vocal production tool that provides Antares' world-renowned real-time pitch correction. Users just set the key and scale of their track, adjust the Retune Speed for their desired effect, and Auto-Tune EFX 3 does the rest. For songs with complex chord progressions or modulations, they can optionally set up custom scales or use their host's automation facility to allow the processing of virutally any vocal line.
