Auto-Tune Mobile brings vocal pitch correction to vocal performance, using Antares' world-class Auto-Tune® technology. Now Antares' professional pitch correction recording studio technology is available for local performers to use live, on stage, or in recording apps on your iPhone / iPad.

The Auto-Tune Mobile app does not do anything until you sing through it. When you sing, Auto-Tune Mobile detects what note you are singing, and corrects the pitch of your notes, to the nearest valid note, from the ones you select on the screen. The corrected vocals go out through the speakers (when you turn on Audio Out); also Auto-Tune Mobile is compatible with other apps if you wish to record.

Connect Auto-Tune Mobile to your sound system between your microphone and your P.A. / speakers to use Auto-Tune Mobile in a live performance setting. Use a microphone audio interface device to connect the 1/8 inch jack to your microphone line and the headphone output to your sound system. Turn on Audio Out on the Auto-Tune Mobile app to get audio to pass through the system. If you turn on Audio Out without connecting to your sound system, you are likely to hear the internal feedback of the internal speaker to the internal mic. Adjust your mic and speakers so there is no feedback.

Vocals are corrected to the nearest pitch based on the key and scale of the song, or to a set of melody notes selected on the screen. Use the Chromatic scale when you don't know what key or scale a song is in. This is the easiest way to correct your voice to the nearest pitch.

The Retune speed is the time it takes for Auto-Tune to pitch correct your voice. The Normal Retune speed is a setting of 50 msecs -- this gives a natural humanized pitch correction effect. Normal Retune speed is appropriate for a moderate tempo song, for example a song at 120 bpm with a melody in eighth notes.

A funky or fast tempo tune, or a song requiring sixteenth note precision, will likely require a Fast Retune speed. The Fast Retune speed corrects notes within 25 msecs; this is better for faster notes. For slow songs or ballads featuring long held notes, the Slow Retune speed (75 msecs) may provide a more natural sound.

In addition to natural sounding pitch correction, you can also apply the iconic Auto-Tune effect. The Auto-Tune effect in essence retunes your pitch immediately (in 0 msecs). Ironically, if you sing really well, there is not much correction for Auto-Tune to do. The Auto-Tune effect is most noticeable when you are off key or you slide into a note. Also when you set the app to the Auto-Tune Effect setting, a meter appears at the top (red bouncing ball) that visually indicates whether you are singing sharp or flat.

The Bypass button is provided as a quick way to stop and start adding the effect as you sing.

Auto-Tune Mobile conforms to the Inter-App Audio (IAA) standard so you can use Auto-Tune with your other IAA apps. Notice when using with GarageBand that the Auto-Tune filter takes effect as you record the track. If you want to pitch correct a pre-existing vocal you will need to replay it outside of GarageBand and re-record it to a new track. Midi control of pitch correction is included, so you can connect a Midi keyboard and direct the vocals to sing on a particular melody or on a set of scale notes as pressed on the keyboard. Midi note presses will show up in red on the app.

Auto-Tune Mobile is Audiobus compatible, allowing Auto-Tune Mobile to work with your other iOS music apps. Auto-Tune Mobile acts as a filter in the “Effects” category, so you can apply pitch correction and the Auto-Tune effect to other Audiobus-compatible apps. (see

Update hot fix

Previous Bugs:

1. App wouldn’t start up or run in standalone, crashes, crashing on iPads and iPhones on multiple devices, but AUv3 instances worked (for me). But ⬇️
2. App would have feedback issues and other sound distortions on tracking and your recording playback.

Current Bugs:

1(2). App would have feedback issues and other sound distortions on tracking and your recording playback. And if you try record that sound for reference, sometimes it would not pick up the recorded sound while it’s in a effect slot or would just be dry vocals with distortion, sometimes both.

I have tested this in multiple daws(MultitrackDaw, Auria(Pro), GarageBand, Aum), standalone and in Audiobus. This is just as big of a issue as the crashes/crashing bug that was fixed with this patch.

But I have faith in this developer because of this crash hot fix and the fact the dev reached out to me so quickly to help fix the crashing issues. So my standing is a fair one right now with hopes that these 🐜 🐛s are ironed out with another quick update.

Will update when fixed!

Developer Response ,

@adon, I am trying to duplicate your problem now. iOS 12.2 works fine here so now it's a matter of looking into the 2018 iPad Pro. If you could contact me directly at, I would like to work with you through TestFlight to get this fixed. Thank you

It needs work

I try to record it on GarageBand using the interface audio at first and it was working fine the only problem is the latency is off and makes me off beat every time I record a song and whenever I use the interface it always has a popping noise when I start playing the song and as for the audio unit settings that needs work too sometimes whenever I record something using the audio unit it makes me off beat it deletes the key I had it on previously and it makes my voice sounds detune and I don’t never have it on detune settings which is weird can you pls fix this I need help pls and thanks!! And pls fix it where US Auto-Tune users can record on beat instead of off beat which would be fix the latency

Auv3 still needs work

While I’m glad this finally got updated to an Audio Unit, it still needs work. When I use it in Cubasis, most of the time I have to change the key and scale again because it goes back to C chromatic, even if I selected a or e minor. It need to remember the last settings we used, also a lot of time when I go to edit Auto-Tune, the interface isn’t there at all and I have to close and reopen Cubasis. Please put in a little more work and it will be good to go.
