Paul Lemere’s Autocanonizer automatically turns any song into a canon — via evolver.fm.

On the Autocanonizer site they’ve got a library of some songs that have been autoanonized. As they play, a graph keeps track of the way new pieces of the song are layered in.

It analyzes any song you upload, looking for segments that would harmonize well with each other…then plays them at the same time.
