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. New - Support for streaming "Apple Music" audio! Note: Some functions such as "Pitch change" and "Equalizer" are not available when playing "Apple Music" songs. Please note: According to Spotify, third party apps will not any longer have access to streaming Spotify content in a way that works for slowing down / pitch change audio starting September 1, 2022. This will affect Amazing Slow Downer. This means that you should NOT buy Amazing Slow Downer if playing Spotify content is your only use of the app. This change does NOT affect any other type of audio content that Amazing Slow Downer can play back.
