From the developer:
mTrax is a revolutionary tool designed to help you become a better musician, fast.
mTrax is an Audio File Slow Downer, a Guitar Trainer, a Speed Trainer, on top of a Music Player.
You can easily identify and save the difficult sections of a song (intros, riffs, breaks, solos and outros) so you can loop through them at much slower speeds, slow enough to learn them note by note or hear fingering subtleties.
