COVER SONG IDENTIFICATION WITH IFF 0 PITCH CLASS PROFILES

The extraction of time-dependent Pitch Class Profiles (PCP) is widely used in machine listening. PCP describes effective note amplitudes at a given point in time. Our PCP extraction methodology ([1]) was originally developed for rhythm and harmony detection. It has proven very effective and is used in our free Winamp plug-in, Easy Chords. This paper describes the results of applying our PCP extraction approach to cover song identification.
