Then, we tried another classifier to improve our accuracy. We took the mean of mfcc and “chroma_stft”, “chroma_cqt”, “chroma_cens”, “rms”, “spectral_contrast”, “spectral_bandwidth”, “tonnetz”, “zcr” features and applied Decision Tree algorithm. Accuracy is 0,35.

Then, we used XGBoost as classifier. Result of this algorithm is 0,40.
