The Auto-Tune EFX Vocal Toolkit provides powerful, easy-to-use tools for creating great vocal tracks. It includes three great plug-ins: Auto-Tune EFX, which corrects pitch in real-time or creates the Auto-Tune Vocal Effect; Harmony EFX, which creates up to five-part vocal harmony from a single voice; and Mic Mod EFX, which makes the microphones you own sound like the microphones you wish you owned.
