چکیده

In the analysis of musical acoustics, we usually use the power spectrum to describe the difference between timbres from two music instruments. However, according to our experiments, the power spectrum cannot be used as effective features for erhu instrument identification. In this paper, we use MFCC (mel-scale frequency cepstral coefficients) as features for music instrument identification using GMM (Gaussian mixture models); the result is very encouraging. MFCC and GMM are commonly used in speech/speaker recognition with success. This paper demonstrates that MFCC and GMM can also be used for erhu instrument identification. Immediate extension of the current work includes MFCC-based music instrument assessment and music acoustic analysis.

Instrogram: Probabilistic Representation of Instrument Existence for Polyphonic Music

This paper presents a new technique for recognizing musical instruments in polyphonic music. Since conventional musical instrument recognition in polyphonic music is performed notewise, i.e., for each note, accurate estimation of the onset time and fundamental frequency (F0) of each note is required. However, these estimations are generally not easy in polyphonic music, and thus estimation erro...

Music Classification based on MFCC Variants and Amplitude Variation Pattern: A Hierarchical Approach

In this work, we have presented a hierarchical scheme for classifying music data. Instead of dealing with large variety of features, proposed scheme relies on MFCC and its variants which are introduced at the different stages to satisfy the need. At the top level music is classified as song (music with voice) and instrumental (music without voice) based on MFCC. Subsequently, instrumental signa...

Musical Genre Classification by Instrumental Features

Automatic musical genre classification is very useful for many musical applications. In this paper, the features of instrument distribution and instrument-based notes are proposed to represent the high-level characteristics of music. Experimental results show that the proposed features have a good performance in musical genre classification. Comparison between our proposed features with the com...
