This is an acoustic study of prosodic effects on segmental durations with reference to syllable structure, stress, focus and tempo in Greek. Disyllabic nonsense words with one, or two, or three consonants in the initial syllable were examined in stressed/unstressed, focused/unfocused and normal/fast tempo productions in a carrier sentence contexts. The results indicate that: (1) syllabic onset ...

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...

There are many applications for which we would like to be able to track the ‘beat’ of a piece of recorded music – analogous to a listener’s foot-tapping. This paper describes our beat-tracking system, which operates by first estimating a global tempo (via autocorrelation of an ‘onset strength’ signal), then using dynamic programming to find the best sequence of beat times through the whole piec...

The research described in this paper focuses on global tempo transformations of monophonic audio recordings of saxophone jazz performances. More concretely, we have investigated the problem of how a performance played at a particular tempo can be automatically rendered at another tempo while preserving its expressivity. To do so we have developed a case-based reasoning system called TempoExpres...

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...

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...

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 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...

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...

O presente artigo apresenta um estudo contrastivo entre as propostas de análise do tempo na primeira e segunda edições do HAREM. Discutimos, entre outros aspectos, as principais vantagens e inconvenientes de uma e outra, tendo em linha de conta os prinćıpios teórico-metodológicos subjacentes ao modelo geral do HAREM. A discussão é feita com base nas expressões temporais compreendidas nas colecç...
