This paper discusses an approach for the feature extraction for audio mood classification which is an important and tough problem in the field of music information retrieval (MIR). In this task the timbral information has been widely used, however many musical moods are characterized not only by timbral information but also by musical scale and temporal features such as rhythm patterns and bass-line...
In this paper, we have presented a study on content-based classification and similarity analysis among 8 typical genres of Chinese traditional opera. Acoustic features are extracted and different classifiers are evaluated, the results show that the quadratic classifier works best, its average classification accuracy can achieve 82.4%. After the similarity analysis, some interesting conclusions are...
Recently, a generalized correlation function called correntropy, extracting both the time structure and the statistical distribution of time series using kernel methods, have been proposed. In this work, the statistically independence criterion obtained using correntropy has been used in separation of different musical instrument samples playing the same note.
Sight-reading is the ability to read and perform music from a written score with little or no preparation. Though an integral part of musicianship, it is rarely or minimally addressed in traditional music lessons. In this paper, we describe a real-time system for sight-reading evaluation of solo instrumental music. The system is trained to recognize monophonic and polyphonic music from acoustic instruments...
We present the experimental results of classification and retrieval of Thai music using TreeQ (a tree-structured classifier) and LVQ (Learning Vector Quantization) algorithms in this paper. We use the HTK Toolkit in preprocessing acoustic signals including feature extraction from the Thai music collection. The training set consists of 250 songs -50 songs from each of the 5 genres. Training is divided...
We present and analyze a machine learning technique to determine from an input sung vocal waveform if falsetto (also known as the head voice) is being used. Such a system may be used to tune signal processing parameters, ideally in real-time, for such applications as intelligibility enhancement of high-pitched sung notes, and other musical systems which tune signal processing parameters according...
