Abstract :
By using the entropy values computed in temporal and spectral domain, the variations of musical signals can also be followed. In this study, the normalized entropy values computed in both domains are proposed to be used as features. These entropy based features are compared with similar features like temporal and spectral centroid, spectral flatness, and spectral spread. Then, their performances are investigated for classification of musical instruments.
