Research of Chord Recognition based on MPCP

In this paper, five different methods in music recognition are discussed, a new character MPCP is proposed in Chord Recognition. The new character overcome the limitation of the traditional PCP and MFCC, apply for recognition system by combining both characteristics. For features we use MPCP vectors, it is trained by HMM, estimated parameters by Baum-Welch algorithm, finally we acquired accurate chords by Viterbi. The experiment show that the new character perform over than PCP and MFCC for Chord Recognition.
