If you're a musician who likes to learn new songs and techniques by listening to the same piece of music over and over but wish that the music could be played a little slower, then you'll enjoy Amazing Slow Downer Lite.

You can repeat any section of the music at full speed, slow it down or even speed it up by changing the speed between 25% (1/4 of original speed) and 200% (double speed) without changing the pitch!

Change the tuning or musical key? No problem, Amazing Slow Downer Lite handles that as well.

Setup seamless loops by touching the "Set" buttons during playback.

Amazing Slow Downer Lite is the ideal tool for any musician, transcriber or dancer wanting to improve their skills.

Important notes:
1. This free "Lite" version is restricted to play the first quarter of an audio file.
2. Cannot play DRM protected files from the iTunes store (m4p and audio book files).

A great app for what I need

This is a great application for what I need. I'm a professional solo musician and backing tracks are a big part of my show. Being able to import audio files to edit the time the tempo and the key ,and then export them to my applications on my tablet where I can play them live during my show . It works perfectly for me even with key changes five or six steps above or below for that reason I give it five stars. I also use AudioStretch which is a similar application but I like this one better . Want to thank Ronimusic for this application and another very useful application that I use a lot Sweet MIDI

This app has so much potential but the fact that you can’t sing the whole song makes it extremely difficult to know if you can carry the whole song vocally. All the higher notes, the REAL kickers are building throughout the song. Also the key should be presented at the beginning of the sing along with the key we need. That’s what the app is for after all.

Super bummer.

Looping in time is way too hard.

Good app, simple interface, does what it says. Good that it it does fractional pitch shift for songs not tuned to the same pitch as your instrument. But looping is extremely hard and takes forever to get right, in time to a song. After you do get it right the forward and x 2 buttons are great.
