This app is only available on the App Store for iOS devices.
Key+ is a handy tool for estimating the musical key of digital recordings and live audio. A must-have for musicians and DJ's, Key+ analyzes audio and returns both the key and it's relative major or minor signature.
What's New in Version 2.2
I like it
Works well, setting sample rate at a longer time helps.
It's not perfect but mostly correct, some songs are very complex and hard for software but most popular music songs work, I use it when playing harmonica!
Great for singers
Sing into the microphone until the percentage at the bottom of the screen gets to 100%. And up pops the key you're singing in.
Good but needs some work
The app works well for instrumentals. If there are voacls, it will throw off the app. It's good but of course could use work.
