## Auto-Key Description
Detect the musical key of any tune whether in the studio or on the go. Instantly share and sync the musical key with your Auto-Tune session running on your computer DAW.

Auto-Key detects the key by capturing a few seconds of audio and returns the most likely musical key. It also returns the diatonic key. 

You can use Auto-Key mobile on any audio coming from a speaker or from an acoustic instrument or a voice. Tap on the Auto-Key logo in the app home screen to find the key. 

Auto-Key Mobile was developed by Antares Audio Technologies, the inventors of Auto-Tune®.

## Auto-Key Reviews in United States

### *---- "Sign in to use"
Why do I have to create an account to use the app for free? Ridiculous.
-- MusicMan2797, 2024-12-29

### ***** "The Gold Standard. Fast & No Frills."
Can’t wait to see what they do next.
-- RJB_2, 2024-10-08

### ***** "Easy and actually works"
Use it every day for instruments and vocals
-- ST1025, 2024-10-08

### ***** "Auto-Key"
Super helpful product, great job
-- Tobot 3000, 2024-10-08

### ***** "Great app for making music !!!!"
Love this app. Helps me with my vocals and ties into Auto Tune seamlessly.
-- MW1234!!, 2024-10-08

### *---- "Stinks"
This app worked well.   Now it won’t work unless I log in or create an account, but it won’t let me log in or create an account.   Just another useless app in the list I guess. 
It does not show a cost in the App Store just the “open” button.
-- Pastor Allen Haughton, 2023-11-15

### ****- "Mostly accurate, but not always"
The app works pretty well and usually gets the key right. But I noticed when I was testing it that it doesn’t seem to be able to recognize modes other than major and natural minor. It will give you a key that has the same number of flats or sharps, but with the wrong starting note. For example, I tested it with a song in Bb Dorian, and it told me that it was Ab Major. 
Other than that, it works just fine.
-- i have to make a screen name?, 2023-08-02

### ***** "Cool app"
I really like this app
-- cool voice checking app, 2023-07-23

### **--- "This would be great if…"
It would be great if we could use this app without having to login or create an account. I just need a simple app that detects key, and this app does that well, most of the time.

While using the app, I click to detect key and now forced to create an account to continue using 1 simple feature. No thanks, why do you need my full name, email everything else for a key detection program?
-- INF1N17Y, 2023-05-18

### ***** "Actually Really useful"
This is exactly what I needed, Although some may say its “inaccurate” I disagree I think its pretty accurate considering its an external microphone from your phone. I produce music and this has helped me so much, I love it.
