Amazing Slow Downer

By Roni Music

Open iTunes to buy and download apps.


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.

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 handles that as well.

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

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

Important notes:
Cannot play DRM protected files from the iTunes store (m4p and audio book files).

Great tool

The title says it all. This is so useful. I do wish there were a way to reorder the songs in the library. I have a lot of active clips and would prefer to group them. Though perhaps there is a way to do this? I don't see a support forum, which would be a helpful resource for such questions.


The Amazing Slow Downer is an absolutely fantastic and necessary tool for a high level of musical productivity. And has been for years. Dear Apple, please support this app to allow import of DRM protected songs from the iTunes subscription, and make it function well with VoiceOver for accessibility.

Good...but confused

I wanted to speed up a song just a bit so I downloaded this app. I went to export it but could not find it anywhere in the music library on my phone. Where did it go once I pressed the export button?
