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).

Full Endorsement

As a musician and teacher of music, I have found the Amazing Slow Downer an invaluable resource for myself and my students.

I first purchased the program for my Macbook Pro and was very impressed at the flawless control of time and pitch, which for me are the critical tools with this sort of program.

You can literally bring a track to almost stand-still without any noticable loss to audio quality, so even the absolute beginner students are able to play along to the music of their choice. This makes them feel good about their progress and makes me feel satisfied knowing they are establishing a strong sense of rhythm straight away.

The advanced players are able to take on virtuoso pieces at a moderate tempo and bring the speed up progessively.

The pitch control allows me to set any key to backing tracks for vocalists with full confidence that the playback will be uncompromised. This makes studio time and performance a breeze.

I was very interested to see whether Roni Music had come up with an equal standard for this app, and indeed they have. Plus, uploading via web browser is very straight forward and fast.

I use this on my iTouch which makes it very convenient for any given situation.

I believe credit is due where deserved, and I wish to personally thank the Roni Music team for creating an app that makes my business work better and personal life creative and fun.

Cheers guys, Lars.
