Autotrebles

In our EECS 351 class at the University of Michigan, we are designing an auto-tuning system for guitar. Our algorithm takes an untuned sequence of single notes or chords as an input and outputs the in-tune version of the same sequence. In the three stages of our project, we progress from tuning a single note, to a series of notes, to tuning entire chords, where multiple, out-of-tune notes are played simultaneously. The system has been optimzied for the range and amplitude of notes played on a guitar, but could easily be expanded to work for most musical instruments or even voice recordings.
