Amazing Slow Downer - Short Review

Music Tools

Amazing Slow Downer is a versatile and powerful tool designed for musicians, transcribers, and dancers who need to manipulate audio to enhance their learning and practice experience.

Key Functionality

  • Speed Adjustment: The software allows users to adjust the speed of audio files between 25% (one-fourth of the original speed) and 200% (double speed) without altering the pitch. This feature is particularly useful for learning complex passages or techniques by slowing down or speeding up the music as needed.


Key Features

  • Pitch Adjustment: Users can change the pitch of the music in real-time, adjusting it in semitones or even finer increments (cents) to match different musical keys or to tune instruments. The pitch can be adjusted up to /- 12 semitones, covering all musical keys.
  • Looping: Amazing Slow Downer enables seamless looping of specific sections of a song. Users can set loop points by moving sliders or tapping the “Set” buttons, allowing for repetitive practice of challenging parts.
  • Equalizer (EQ): The software includes an equalizer that allows users to boost or cut the volume at different frequencies. This is helpful for isolating specific instruments or sounds within the music, making transcription easier.
  • Channel Mixing: The “Mix” slider allows users to adjust the balance between the left and right audio channels, which can be useful when the instrument of interest is more prominent in one channel.
  • File Compatibility: Amazing Slow Downer supports a wide range of file formats including MP3, WAV, AIFF, Windows Media Audio, Ogg, FLAC, and AAC/M4A. However, it does not support DRM-protected files or streaming services like Spotify and Apple Music (with some limitations for Apple Music on the iOS app).
  • Real-Time Processing: All audio adjustments are made in real-time, allowing for immediate feedback and continuous practice without interruption.
  • Export Capabilities: Users can export the modified audio files with the selected settings for speed, pitch, and other adjustments, which is convenient for creating practice materials.


Platform Availability

Amazing Slow Downer is available on multiple platforms, including iOS, Android, Windows, and Mac OS, making it accessible to a wide range of users regardless of their preferred operating system.

In summary, Amazing Slow Downer is an indispensable tool for musicians and other performers who need to manipulate audio to improve their skills. Its robust features, including speed and pitch adjustment, looping, equalization, and real-time processing, make it a valuable asset for anyone looking to enhance their musical practice.
