About this app

Slow Down Music!

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.

Outstanding sound quality!

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

Note: Although we have never officially supported playback of Spotify audio, it nevertheless has worked very good. But according to Spotify, third party apps will not any longer have access to streaming Spotify content in a way that works for slowing down audio starting September 1, 2022.

Ratings and reviews

Well, after using this for almost 10 years now, it's still my go-to app for learning a drum part. I set out my sheet music and create a loop for each bar or so of music. Then work up to speed the part. When the music is slowed down, it is crystal clear. There are other apps that isolate the drums or guitar or bass, but I found that only useful if I just want to play the part. It really doesn't help me practice like this does. 5 stars.

They made it much worse. It copies all played music onto internal storage. This also breaks internal file picker which now has no way to access the SD card since it starts with the directory of the last song it played. Still great for learning music, but there's gotta be a better way. A great app that I paid for and used for 10 years is spoiled. I want the old version please.

I really love this app. The Spotify linkage gives me access to all my playlists so I can slow down or transpose nearly any song I want. At first I couldn't find the saved loops but then I found out the loops are stored with each song, so you have to first load the song you want to learn, and then all the previously saved loops appear. You can rename them, delete them, etc. You can't export Spotify songs, but you can export songs from your own collection. I haven't found a fine-tuning ability to adjust the start and end points more precisely - that would be nice, so you can make loops that stay right on the beat when looped over and over.
