We believe that this approach can be further extended to use multidimensional unsupervised machine learning techniques, such as clustering, to obtain new insights into timbre characterization.So one measure is the time allotted to apply a time frame in music and for the rhythm however, the pattern may change from measure to measure. We postulate that the proposed descriptors are sufficient to describe the timbral characteristics in the aerophones studied, allowing their recognition using the acoustic spectral signature. acoustics, using the spectra obtained by the Fast Fourier Transform (FFT), which allows describing the timbre of wooden aerophones (Bassoon, Clarinet, Transverse Flute, and Oboe) using individual sound recordings of the musical tempered scale. In this paper, we present a minimum set of dimensionless descriptors, motivated by musical.
Evaluating the musical timbre allows not only to establish precise musical parameters but also the recognition, classification of musical instruments, and assessment of the musical quality of a sound record. The quantitative assessment of the musical timbre in an audio record is still an open-ended issue.

In this context, it was tried to demonstrate that the external control of the Executive Power is an essential duty and inherent to the councilor activity, being indispensable the councilman’s dedication for its full exercise. Erário.ĮXERCISE OF EXTERNAL CONTROL BY THE SEEKER AS AN INSTRUMENT OF PROTECTION OF THE STATE MONEYĪbstract: The objective of this work is the study of the external control of the executive power by the councilor, with emphasis on the characterization of the importance of the function for and the protection of the treasury. Neste contexto, procurou-se demonstrar que o controle externo do Poder Executivo é função-dever essencial e inerente à vereança, sendo imprescindível a dedicação do vereador para o seu pleno. P class="resumo">Este trabalho tem por objeto o estudo do exercício do controle externo do Poder Executivo pelo vereador, com ênfase na caracterização da importância da função para a proteção do erário. The generalization of the method is suggested for all families of musical instruments.
It is concluded that the stage of sound evolution as the attack and sustenance, allow the establishment of harmonics whose powers are fundamental to define the timbric "color" associated with each instrument, as well as the number of harmonics allowed to establish parameters of "sound identity", useful for the generation of a coefficient extracted from the obtained spectral analysis, which allows to advance in the characterization of the Sonority. This work presents, from a spectral analysis of the timbre with the use of Fast Fourier Transform (FFT), Spectral Power Density (DPE) and Spectrograms, the characterization of the subjective concept of "sonority", for some instruments of the Woodwind family: Piccolo flute, transverse flute, clarinet and oboe. In the field of musical acoustics, it is well known that the sounds coming from musical instruments depend on several acoustic physical parameters such as Intensity, Frequency, and the number of harmonics, as well as other aspects including, association with its manufacturing process, such as geometry and materials used for construction.
This definition obeys to subjective musical parameters associated with "color balance", "sound amplitude", among others.
The sonority is one of the definitions widely used by musicians when trying to define the color or timbral balances associated with individual or groups of instruments, such as for ensembles or orchestras.
