From Roni Music:
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 for Mac. This PowerPC program reads music directly from your CD-ROM drive and slows it down between 1% and 400% using a "time-stretching" method which does not change the pitch, regardless of the speed! Most programs of this sort require you to record the music first. Not with the Amazing Slow Downer. It processes the music in real time - just insert the CD and press the play button! You may also import and play MP3, AIFF and Wave files. Other features include increasing the music speed up to twice the normal rate, pitch adjustments in semi-tones at full or lower speed, and more.
