Music Instrument Classification using Nontonal MFCC
Yi Wu, Qi Wang, Ruolun Liu · 2017
Combined with the sounding mechanism and cepstrum, a new model is proposed to describe the timbre more precisely, together with the nontonal Mel-frequency cepstral coefficients (NMFCC) derived from the nontonal spectral content which relates closely to the resonator.A better performance is observed from the experiment results of five classifiers over the isolated instrument samples of 13 instruments of different instrument families.The NMFCC method outperforms the one using MFCC with an accuracy rate of 97.7% for individual instruments.
