This paper discusses music analysis in relation to images of musical sound using spectral or Fourier analysis. Fourier analysis allows us to make pictures of musical performances, which reveal the fundamental, overtones, and complex... more
Most of the prior research which has been carried out on audio recognition has been done in speech and music. Only in recent years, dozens of emerging works have been conducted on Environmental Sound Recognition and has gained importance.... more
Outre le choix des notes, qui est prescrit par une tradition commune, qu’est-ce qui distingue un improvisateur jazz d’un.e autre ? Qu’est-ce qui constitue leur « son », leur « signature » ? Les méthodes d’analyses plus traditionnelles... more
Power quality disturbances present noteworthy ramifications on electricity consumers, which can affect manufacturing process, causing malfunction of equipment and inducing economic losses. Thus, an automated system is required to identify... more
Convolution reverb is the process used for reverberating a signal by an impulse response of an actual space. The product of this operation is a third signal, containing reverberation of the space where the impulse response is captured.... more
“Los bosques de cemento” es una composición musical para orquesta sinfónica de unos 6 minutos de duración compuesta a finales de 2013. Esta obra resultó ganadora en el I Concurso de Composición para Orquesta Sinfónica “Emilio Lehmberg”... more
The presence of K-pop production in Norway is not coincidental. Norwegian producers have identified economic and artistic market opportunities in Korea, while the Korean music industry has encouraged non-domestic producers to export pop... more
Pilar Bayona, one of the foremost Spanish pianists of the twentieth century, has been the baseline of this study as her fi gure has hitherto not been studied from the technical and interpretive perspective. Their interpretations of... more
Laptop composition – the creation and performance of music primarily using laptop computers – emerged as an important musical activity in the last decade of the twentieth century. While much has been written about the cultural and... more
This unique study investigates the frequency spectrum of certain Rosicrucian vowel chants using PRAAT (Boersma 2001, 341-345) software and analysis. Certain Rosicrucian vowel sound intonations, which are shared by other traditions, were... more
This paper reveals concordances between pitch space and vowel sounds in Hildegard von Bingen’s O rubor sanguinis. The antiphon not only displays a cogent pitch and register structure, but also projects a vivid timbre design created... more
The current Trabajo de Fin de Grado aims at describing, in a first theoretical approach, the basics of the phenomenon called “aspiration” that occurs in English and, in the practical approach, at analyzing previously recorded samples of... more
ABSTRACT This paper presents a novel approach to categorize dolphin whistles into various types. Most accurate methods to identify dolphin whistles are tedious and not robust, especially in the presence of ocean noise. One of the biggest... more
Most of the current supervised automatic music transcription (AMT) models lack the ability to generalize. This means that they have trouble transcribing real-world music recordings from diverse musical genres that are not presented in the... more
The periodic inspection of railroad tracks is very important to find structural and geometrical problems that lead to railway accidents. Currently, in Pakistan, rail tracks are inspected by an acoustic-based manual system that requires a... more
While analyses of vocal music often highlight connections between textual meaning and musical structure, less common is the study of language sounds in relation to musical structure. This presentation explores Guillaume de Machaut’s... more
Decreasing road accidents rate and increasing road safety have been the major concerns for a long time as traffic accidents expose the divers, passengers, properties to danger. Driver fatigue and drowsiness are one of the most critical... more
Facial and head actions contain significant affective information. To date, these actions have mostly been studied in isolation because the space of naturalistic combinations is vast. Interactive visualization tools could enable new... more
This paper proposes an active contour algorithm for spectrogram track detection. It extends upon previously published work in a number of areas, previously published internal and potential energy models are refined and theoretical... more
A Byzantine Music piece performed by a well recognized chanter is used in order to derive experimentally the mean frequencies of the first five tones (D – A) of the diatonic scale of Byzantine Music. Then the experimentally derived... more
This article explores the timbre of Thai classical singing with an emphasis on uan, a wordless vocalization based upon specific vowels and consonants, using spectrographic images. Spectrographs are computer images that visualize the... more
