Apresenta uma avaliação qualitativa intitulada rede semântica natural proposta por Figueroa, González e Solís (1981) sobre a concepção dos professores de educação infantil e ensino fundamental 1º e 2º ciclos de talento musical e a importância da música no ambiente escolar. Os resultados confirmam o julgamento, muito freqüente, do privilégio de poucos ¿dotados¿ de talento nato para o fazer musical e revela um reconhecimento das contribuições da música para o desenvolvimento cognitivo, afetivo, social e motor das crianças, embora as concepções dos professores sobre a música na escola não apresentem categorias que envolvam a prática musical como o cantar, tocar ou fazer música. Esses resultados provocaram algumas necessidades. Para tanto, pretendeu-se conhecer o processo de construção das noções musicais em crianças de educação infantil e propor um caminho de reflexão sobre as possibilidades musicais comum a todos. Assim, o estudo apresenta o registro gráfico do som realizado por crianças de 3 a 6 anos de idade que visa analisar à luz da psicologia genética o processo de representação gráfica do som e sua relação com a natureza da inteligência. Foram propostas duas observações, uma do ambiente sonoro da escola e outra da percepção de quatro instrumentos musicais: o par de cocos, o metalofone, a queixada e a flauta doce. Os estudos permitiram observar uma evolução do registro do som que parte das garatujas, sem semelhanças com os sons emitidos, passando pelo registro da fonte sonora, inicialmente sem nenhum sinal acompanhando o corpo do objeto e posteriormente com sinais que indicam o som como um prolongamento do objeto sonoro. Algumas representações apresentaram a evocação de objetos ausentes, características nas crianças pré-operatórias. Os registros mais evoluídos apresentaram o som desligado da fonte sonora se mantendo estável pela generalização do significante para um mesmo significado, caracterizando a passagem de símbolo para signo. A partir dessas observações, pôde-se concluir que a compreensão dos signos musicais exige a construção de estruturas mentais, fruto das explorações e invenções organizadas e criadas pelas crianças em contato com os elementos sonoros e das possibilidades de transformação do invisível para visível por meio da escrita, relacionando os signos arbitrários e convencionais às suas experiências anteriores. À guisa de conclusão, são apresentadas algumas reflexões sobre as práticas musicais decorrentes da exploração sonora e de suas representações escritas, possíveis de serem realizadas por qualquer profissional da educação, independente de ser ou não um especialista em música / Abstract: The present research intends to argue the importance of the musical activities for the work with children in the daily one of the school. It presents a qualitative evaluation intitled net natural semantics proposal for Figueroa, González and Solís (1981) on the conception of the professors of infantile education and basic education 1º and 2º cycles on musical talent and the importance of music in the pertaining to school environment. The results confirm the judgment, very frequent, of the privilege of few "endowed" with born talent to make musical comedy and disclose a recognition to it of the contributions of music for cognizance, affective, social and motor the development of the children, even so the conceptions of the professors on music in the school do not present categories that involve the practical musical comedy as singing, touching or to make music. These results had provoked some necessities. For in such a way, it was intended to know the process of construction of the musical slight knowledge in children of infantile education and to consider a reflection way on the musical possibilities common to all. Thus, the study it presents the graphical register of the sound carried through for children of 3 the 6 years of age that it aims at to analyze to the light of genetic psychology the process of graphical representation of the sound and its relation with the nature of intelligence. Two comments environment the school the sonorous another one of the perception of four musical instruments had been proposals, one of and: the pair of coconuts, metalofone, the jaw and the flute candy. The studies had allowed to observe an evolution of the register of the sound that has left of garatujas, without similarities with the emitted sounds, passing for the register of the sonorous source, initially without no signal following the body of the object and later with signals that indicate the sound as a prolongation of the sonorous object. Some representations had presented the absent, characteristic object mandate in the children daily pay-operative. The evolved registers more had presented the off sound of steady the sonorous source if keeping for the generalization of the significant one for one exactly meant, characterizing the ticket of symbol for sign. To leave of these comments, it could be concluded that the understanding of the musical signs demands the construction of mental structures, fruit of the explorations and inventions organized and created for the children in contact with the sonorous elements and of the possibilities of transformation of the invisible one for visible by means of the writing, relating the arbitrary and conventional signs to its previous experiences. To it stews of conclusion, are presented some reflections on the practical decurrent musical comedies of the sonorous exploration and its written, possible representations to be carried through for any professional of the education, independent of being or not a specialist in music / Mestrado / Psicologia, Desenvolvimento Humano e Educação / Mestre em Educação

Due to the accelerated growth in digital music distribution, it becomes easy to modify, intercept, and distribute material illegally. To overcome the urgent need for copyright protection against piracy, several audio watermarking schemes have been proposed and implemented. These digital audio watermarking schemes have the purpose of embedding inaudible information within the host file to cover copyright and authentication issues. This thesis proposes an audio watermarking model using MATLAB® and Simulink® software for 1K and 2K fast Fourier transform (FFT) lengths. The watermark insertion process is performed in the frequency domain to guarantee the imperceptibility of the watermark to the human auditory system. Additionally, the proposed audio watermarking model was implemented in a Cyclone® II FPGA device from Altera® using the Altera® DSP Builder tool and MATLAB/Simulink® software. To evaluate the performance of the proposed audio watermarking scheme, effectiveness and fidelity performance tests were conducted for the proposed software and hardware-in-the-loop based audio watermarking model.

Wind bands have been recording for over one hundred years. Through advancements in both technology and process, recordings have made a monumental impact on the wind band and its repertoire. These advancements have created clarity regarding the performance practice of pieces and helped to preserve the wind band repertoire. Many early works have gained masterwork status due, in large part, to the fact that recordings have preserved them. The increase in popularity of recording and, in particular, the wind band, warrants an investigation into the various aspects of the process. Additionally, gaining insight from wind band professionals who record will help to evaluate the contributions that recording has made to the education of performers and listeners, the preservation of repertoire and the artistic enhancement of the wind band. Each chapter explores aspects of the recording process and how those aspects have shaped the wind band, its repertoire and performance practice. Information from conductors, composers and engineers provide valuable insight pertaining to the educational, historical and artistic components of the recording process. The goal of all involved in the recording process should be the pursuit of technical perfection, which does not eclipse the ultimate musical goals of the project and the integrity of the composer's intentions.

Three original software programs utilizing improvisation and live sampling are presented here, along with a discussion of aesthetic issues raised by each. They are entitled Zur Elektrodynamik bewegter Musiker, Motet, and Gamepad Sampler. These programs vary in the degree of required interaction and in the kind of user control. They are each studies in imitative counterpoint through live sampling, with an approach seeking elegance before solutions. Because of the improvisational nature of these works, there is no standard musical score. Instead the complete Max/MSP source code and a sound recording of performances making use of these programs in varied situations are included. A discussion of issues raised by these works includes aesthetics, ontology, performance, and the role of the composer. Non-interactive indeterminate compositions are ontologically thin, because some composerly agency is required of the performer. An interactive work can be ontologically substantial if it makes distinct and significant contributions to performance, even though it may not make sound on its own. Although reproducibility reduces ontology and eliminates aura, live sampling within a performance can deepen the ontology of the performance by recontextualizing previous events, reframing the original event as the first reference to an abstract musical idea that lies outside the musical performance. Reproducibility also diminishes the aura or stage presence in live performance with computers. Complex feedback systems can be used to create computation instruments: musical instruments whose unique structure resonates in ways not explicit in their programs. As the human condition and the situation of the composer change, definitions of the composer and performer must be revised. Composition is shifting away from the creation of static artifacts toward the design of dynamic systems.

Thesis (M.Mus.)--University of Stellenbosch, 2006. / ENGLISH ABSTRACT: In South Africa there has been an increase over the last few years in audio engineering courses which include modules of study in audio post-production or even offer audio post-production as a major focus of study. From an academic standpoint however, and despite the growth in the local film industry, very little study of this field has been undertaken in South Africa until recently. In 2005, a MMus thesis was submitted at the University of KwaZulu-Natal entitled Acoustic Ambience in Cinematography: An Exploration of the Descriptive and Emotional Impact of the Aural Environment (Turner, 2005: online). The thesis briefly outlines the basic components of the soundtrack and focuses on describing and analysing the properties of ambience, a sub-section of sound effects. At Stellenbosch University, research has recently begun in the fields of film music and Foley (sound effects associated with human movement onscreen). The purpose of this thesis is to provide an overview of audio post-production and the contribution of sound to the film medium. It provides an outline of the processes involved in creating a soundtrack for film and includes a description of the components of the soundtrack and recommendations for practical application. / AFRIKAANSE OPSOMMING: Gedurende die afgelope paar jaar was daar ‘n toename in oudio-ingenieurskursusse, insluitend studiemodules in oudio post-produksie, en selfs ‘n aanbod vir modules in post-produksie as hoofstudierigting. Desnieteenstaande, en ten spyte van die groei in die plaaslike filmindustrie is tot onlangs min akademiese studies op dié terrein in Suid-Afrika onderneem. In 2005 is ‘n MMus-tesis aan die Universiteit van KwaZulu-Natal voorgelê, met die titel Acoustic Ambience in Cinematography: An Exploration of the Descriptive and Emotional Impact of the Aural Environment (Turner, 2005: aanlyn). Hierdie tesis gee ‘n basiese oorsig oor die basiese komponente van die klankbaan, en fokus op die beskrywing en analise van die eienskappe van ambience – ‘n onderafdeling van klankeffekte. By die Universiteit van Stellenbosch is onlangs ‘n begin gemaak met navorsing oor die terreine van filmmusiek en Foley, d.w.s. klankeffekte geassosieer met menslike bewegings op die skerm.. Hierdie tesis beoog om ‘n oorsig te gee van oudio post-produksie en die bydrae van klank tot die filmmedium. Dit verskaf ‘n oorsig oor die prosesse betrokke by die daarstelling van ‘n filmklankbaan en sluit ook in ‘n beskrywing van die komponente van die klankbaan en aanbevelings vir die praktiese toepassing daarvan.

Run-Length-Limited (RLL) channels are found in digital recording systems like the Hard Disk Drive (HDD), Compact Disc (CD), and Digital Versatile Disc (DVD). This thesis presents novel encoding algorithms for RLL channels based on a simple technique called bit stuffing. First, two new capacity-achieving variable-rate code constructions are proposed for (d,k) constraints. The variable-rate encoding ideas are then extended to (0,G/I) and other RLL constraints. Since variable-rate codes are of limited practical value, the second half of this thesis focuses on fixed-rate codes. The fixed-rate bit stuff (FRB) algorithm is proposed for the design of simple, high-rate (0,k) codes. The key to achieving high encoding rates with the FRB algorithm lies in a novel, iterative pre-processing of the fixed-length input sequence prior to bit stuffing. Detailed rate analysis for the proposed FRB algorithm is presented, and upper and lower bounds on the asymptotic (in input block length) encoding rate are derived. Several system-level issues of the proposed FRB codes are addressed, and FRB code parameters required to design rate 100/101 and rate 200/201 (0,k) codes are tabulated. Finally, the proposed fixed-rate encoding is extended to (0,G/I) constraints.
