Tempo estimation plays a fundamental role in music analysis, especially for the automatic processing of large amounts of musical data. In this paper, a novel idea to enhance the estimation of the tempo in musical pieces is described, based on an harmonic/noise decomposition. This separation of the signal into a deterministic and a stochastic part is performed by projecting the signal onto its n...

We present a technique that, given a sequence of musical note onset times, performs simultaneous identi cation of the notated rhythm and the variable tempo associated with the times. Our formulation is probabilistic: We develop a stochastic model for the interconnected evolution of a rhythm process, a tempo process, and an observable process. This model allows the globally optimal identi cation...

In this paper, we present a novel approach to the automatic estimation of tempo over time. This method aims at detecting tempo for music with and without percussion. An onset-energy function is first proposed based on the reassigned spectral energy flux. A combination of Discrete Fourier Transform and Frequency Mapped AutoCorrelation Function is used to estimate the dominant periodicities at ea...

Tempo estimation is fundamental in automatic music processing and in many multimedia applications. This paper presents an automatic tempo tracking system that processes audio recordings and determines the beats per minute and temporal beat location. The concept of spectral energy flux is defined and leads to an efficient note onset detector. The algorithm involves three stages: a frontend analy...

Recent research has studied the relevance of various features for automatic genre classification, showing the particular importance of tempo in dance music classification. We complement this work by considering a domainspecific learning methodology, where the computed tempo is used to select an expert classifier which has been specialised on its own tempo range. This enables the all-class learn...

Tempo is a messaging system designed for timesensitive applications that require low-latency and high data rates. In Tempo, unlike existing real-time messaging systems, most of the policy is delegated by the messaging layer to the application. It is the application’s responsibility to react to information supplied by the messaging layer in order to achieve some performance objective; this makes...
