This paper presents a probabilistic model of temporal structure in music which allows joint inference of tempo, meter and rhythmic pattern. The framework of the model naturally quantifies these three musical concepts in terms of hidden state-variables, allowing resolution of otherwise apparent ambiguities in musical structure. At the heart of the system is a probabilistic model of a hypothetica...

For the peak picking of tempo candidates, applying kmeans clustering on tempo curve is straightforward and leading to good result. But the tempo candidates obtained from tempo curve are limited and lose a lot of information for possible tempi. The study proposes the local maximum peak picking method to increase the number and information of possible tempo candidates. Therefore, the accuracy of ...

An absorptive chemically induced dynamic electron polarization (CIDEP) was generated by the quenching of singlet oxygen by nitroxide radicals (TEMPO derivatives). The spin polarization decay time of the nitroxide (measured by time-resolved EPR) correlates with the lifetime of singlet oxygen (measured by singlet oxygen phosphorescence spectroscopy). In addition, a deuterium isotope effect on the...

In this paper we present a method for learning tempo classes in order to reduce tempo octave errors. There are two main contributions of this paper in the rhythm analysis field. Firstly, a novel technique is proposed to code the rhythm periodicity functions of a music signal. Target tempi range is divided into overlapping “tempo bands” and the periodicity function is filtered by triangular mask...

The estimation of the perceived tempo is required in many MIR applications. However, automatic tempo estimation itself is still an open problem due to the insufficient understanding of the inherent mechanisms of the tempo perception. Published methods only use the information of rhythm pattern, so they may meet the half/double tempo error problem. To solve this problem, We propose to use statis...

For audio music with time-varying meters, tempo estimation is a challenging task. This paper proposes several new low-level features of tempogram to determine pulse the classification of duple/triple meters, which can guide the determination of the overall tempo. After the judgment of meters, then we apply k-means clustering on tempo curve to perform tempo estimation. Index Terms – Tempo Estima...
