The quickest, easiest, most affordable tool for real-time pitch correction and creating the Auto-Tune Vocal Effect (the T-Pain/Cher-style effect).


Powered by the same ground-breaking Evo Voice Processing Technology as Antares Auto-Tune Evo, the latest generation of the worldwide standard in professional pitch correction, Auto-Tune EFX makes Antares-quality pitch processing accessible to anyone engaged in computer-based audio recording.

Designed to make almost everything automatic, Auto-Tune EFX provides two different flavors of the Auto-Tune Vocal Effect as well as real-time pitch correction. Just select your desired effect type, set the key and scale of your track, and Auto-Tune EFX does the rest. For songs with complex chord progressions or modulations, you can optionally set up custom scales or use your host's automation facility to allow the processing of virtually any vocal line.

Pitch Correction

Like Auto-Tune Evo, Auto-Tune EFX pitch correction works by continuously tracking the pitch of your vocal and comparing it to the notes in a (customizable) scale. The scale note closest to the input pitch is identified as the target note. If your vocal’s pitch exactly matches the target note, no correction is applied. If your vocal’s pitch varies from the target note, either sharp or flat, the output pitch is smoothly corrected to the target note

Auto-Tune Vocal Effect

The Auto-Tune Vocal Effect is what is technically known as pitch quantization. Instead of allowing all of the small variations in pitch and the gradual transitions between notes that are a normal part of singing, the Auto-Tune Vocal Effect limits each note to an exact pitch, stripping out any variation, as well as forcing instantaneous transitions between notes.

Here’s how easy it is:

Tell Auto-Tune EFX the vocal range of your track:

Set the Key and Scale (major, minor, or chromatic) of your track:


When you select a Key and Scale, the appropriate Note buttons will light blue to indicate that they are in the scale and that the input vocal can be corrected or forced to those notes:

Depending on the specific vocal line, adding or removing scale notes can give you distinctly different results. Customize your scale by clicking on Note buttons to add or remove them from the scale.

Set the desired Effect Type:

Hard EFX is the classic Auto-Tune Vocal Effect popularized by T-Pain, Cher and many, many others.

Soft EFX is a variation of the Auto-Tune Vocal Effect that allows slight pitch variations and slightly less instant note transitions.

Pitch Correct provides high-quality, real-time correction of intonation problems, while preserving all the expressive nuance of the original performance.
