What Amazing Slow Downer is
Amazing Slow Downer is a music playback tool for musicians who want to learn songs and techniques by listening repeatedly at a reduced speed. It slows music without changing pitch, so a passage can be easier to follow while retaining its original key. On Windows and Mac, playback speed ranges from 20% to 200%, with pitch adjustment available by semitones or cents. The Windows version handles MP3, Wave, Windows Media Audio, Ogg, FLAC, and AAC/M4A files in real time. On iOS and Android, speed ranges from 25% to 200%; mobile users can also create seamless playback loops and change tuning or musical key. Computer editions support control through USB HID devices and MIDI controllers, and the iOS page describes Bluetooth/MIDI remote control. The software is available for Windows, macOS, iPhone/iPad, and Android. Windows and Mac have free trial software, while the mobile pages link to free lite versions. Paid licenses are single-user and separate for each platform: $9.95, paid once for Android, $14.95, paid once for iOS, and $39.95, paid once for Mac/Windows. The listed purchase price includes free email support and updates for at least seven years.
