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).



  • The Best Practice Tool Hands Down!!!!!

    By DudeRock430
    This is the best practice / jam tool! I use it all the time! I have had this for years and it still does everything I need it to do. Wanna jam along or learn a Van Halen, Jimi Hendrix, or SRV tune and don't want to tune down a half step? No problem! Just raise the pitch! Wanna set a loop to play a solo or difficult part over and over? You can do that! Need to slow a difficult part down and slowly increase the speed as you get better? This app can do it! You can even export songs you adjust!!! I use this about every time I play and it is the most important jam app I have hands down!!!
  • Doesn’t work for me

    By RachHarp7
    This isn’t compatible with Amazon music, which is where I have all of my music. I’m disappointed that I spent my money on this app and I wish I had known this before I bought it.
  • LOVE THIS PROGRAM, Should have purchased 3 years ago!

    By Chelle Mandolinist
    I am currently a mandolin student and purchased to learn an advanced solo. I fell in love with this APP immediately and wished I would have bought years ago! You can slow down and learn at a speed to catch every little detail and as you progress, you then reward yourself by increasing the speed! Easy to follow! I only wish it would work with my Bluetooth speaker!
  • Still great after all these years

    The first version of Amazing Slow Downer that I bought was on a floppy disk and ran on my Windows 95 computer. The software was great then and the iOS version available today is even better! Thanks for continuing to develop this useful tool for musicians.
  • Amazing technology

    By André Web
    You can’t judge an app by its user interface. Not to mention the user experience is pretty solid especially for such a difficult conceptual notion. But most impressive is the apps ability to slow down a song without changing the pitch. I’ve tried many apps , including various mixing software and they don’t even come close. This app is a blessing for my life.
  • YAY

  • Does not work with new Apple iOS.

    By littlepigmusic
    iTunes and the new apple iOS protects the music and even though I bought the music, I can only use iTunes to play it. Unfortunately the only way I found out was going to the developer website and reading the faqs

    If your Apple Music was synced to the cloud and you try to play it the music won’t play because apple put some kind of encrypted tag on it. Good luck figuring out how to get music to work with this app.
  • Excellent

    I use this app to help me learn Irish traditional music by ear. The only feature that I wish it had is the ability to download an mp3 directly from the web.
  • Still the Best!

    By Mikes jello
    I first encountered Amazing Slow Downer when it was only a desk top app, and maybe the only of its kind, and the iPhone was still a dream. This app has every bit of that capability and then some. I highly recommend this for musicians.
