Amazing Slow Downer for Mac OS X

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!
