"Tune Transformer is a fantastic app for anyone who would like to change pitch and time of an audio file. Extremely flexible and powerful and a super learning tool for any musician!"
"Just got the new version for IOS 5.1. If you ever rehearse using backing tracks, you need this app! Most karaoke key changers sound awful if you change keys more than 2 steps. I've gone 6 steps up and down with no warble sound! Same with the speed change. No distortion at 50% or 150% speed. I've used Sound Forge to change keys and it is great but this is just as good for a lot less money! Absolutely the best! "
" Tune Transformer is a great app. It allows me to slow songs down and change the pitch so that I
can play chords on my guitar from my Beatles song book in the same key as the music on my iPhone. This gives me time to change chords and not fall behind, as I am a beginner at playing the guitar. It's making learning more fun."
