Amazing Slow Downer provides the means to slow down the music, so you can learn the music in real-time by playing it from a CD, MP3, WAV, AIFF, MP4, WMA and many other file formats.

Other features include: Increasing the music speed to up to twice the normal rate - making pitch adjustments in semi-tones at full or lower speed - setting loop points - using keyboard shortcuts.


Change the speed of the music - from 20% (one fifth speed) to 200% (double speed) without changing the pitch.

Wrong key? Change the pitch in semi-tones - at full or changed speed.

Out of tune? Adjust the pitch in cents (100ths of a semi-tone) to suit your instrument.

Real-time processing - all described above is done in real-time - just insert the CD and press the play button!

Also slows down MP3, AIFF, AAC/MP4 and wave files on your computer in real-time.
