Speedshifter 2.0

Speedshifter is a practice tool from ABRSM that allows you to vary the speed of audio from CD or MP3 without altering the pitch. Simply load a track and turn the dial to slow it down or speed it up - the pitch remains the same. If you load an ABRSM minus one track Speedshifter will know the starting tempo of the track and position the dial automatically at the correct point on the tempo/BPM ring.
