Ratings and Reviews
I am a Audio engineer and every sense I ran across this app it have been a time saver for me for when I am recoding singers who need the auto tune in the right key. This app help me with the key that the song are in so I can set the key and note scale so the auto tune can correct the singer notes. This help me with hearing the key without using it but I still use this app to make sure.
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.
With Family Sharing set up, up to six family members can use this app.
