Personal soundtracks on public transit : personal listening devices and socio-spatial negotiations of students' bus journeys

One way of exploring the power of sound in the experience and constitution of space is through the phenomenon of personal listening devices (PLDs) in public environments. In this thesis, I draw from in-depth interviews with eleven Brock University students in S1. Catharines, Ontario, to show how PLDs (such as MP3 players like the iPod) are used to create personalized soundscapes and mediate their public transit journeys. I discuss how my interview participants experience the space-time of public transit, and show how PLDs are used to mediate these experiences in acoustic and non-acoustic ways. PLD use demonstrates that acoustic and environmental experiences are co-constitutive, which highlights a kinaesthetic quality of the transit-space. My empirical findings show that PLDs transform space, particularly by overlapping public and private appropriations of the bus. I use these empirical findings to discuss the PLD phenomenon in the theoretical context of spatiality, and more specifically, acoustic space. J develop the ontological notion of acoustic space, stating that space shares many of the properties of sound, and argue that sound is a rich epistemological tool for understanding and explaining our everyday experiences.

Edição de Som: algumas perspectivas

Para lá da edição de imagem podemos também editar o som: a fase onde se trata e manipula toda a banda sonora do filme (diálogos; música e efeitos). As ideias e as ferramentas de que nos servimos para editar o som implicam consequências óbvias no produto final. Como tal, a edição de som tem também a responsabilidade de fundir correctamente os sons e as imagens. A mistura é uma tarefa específica que pretende preservar, no fundo, densidade e clareza. Como uma lista de prioridades: o que é que queremos que eles ouçam? Um dos objectivos principais da edição de som é a tentativa de obter um certo tipo de relação interessante entre o som e a imagem: pontuação e amplificação são os recursos principais. Queremos – com o som – despoletar uma descoberta das emoções escondidas no íntimo da audiência. Um filme bem editado permite uma excelente partilha entre os sentimentos dos espectadores e os pensamentos e intenções de quem trabalha o som e realiza o filme.

Auto-poïétique de deux expériences de montage sonore : d'une écoute à l'autre

Notre mémoire de recherche-création a pour point de départ deux conceptions sonores filmiques, auxquelles nous avons contribué en tant que monteur et concepteur sonores. Ces films – et leur bande sonore – ont, par leur forme, leur contenu, mais aussi par la dynamique ayant rythmé leur création, redéfini un aspect ou un autre de notre pratique. Ainsi, au moyen d'une auto-poïétique, nous explorons les différentes conditions de la création sonore mises en jeu, qu'elles soient d'ordre technique – le film Saint-Denys Garneau – ou d'ordre esthétique – le film Ma famille en 17 bobines. Dans chaque cas, nous cherchons aussi à explorer les problèmes poétiques et pratiques posés. Au creux de cette conjugaison de ces conditions émergent alors des outils de médiation, des relations humaines, des mouvements esthétiques et des postures d'écoute qui jettent un éclairage inédit sur notre pratique sonore.

L'interférence musicale au cinéma, à la télévision et dans le jeu vidéo

L’omniprésence de la musique populaire dans le paysage médiatique contemporain fait en sorte qu’il est fréquent de retrouver la même chanson dans plusieurs trames sonores. En s’appuyant sur des théories de l’intertextualité et de la communication, ce mémoire cherche à définir la relation qui s’établit entre deux ou plusieurs oeuvres narratives et / ou interactives partageant une chanson, ainsi qu’à appréhender les effets de ces recontextualisations multiples sur l’expérience spectatorielle et vidéoludique. Le premier chapitre examine les principales fonctions narratives et ludiques de la musique à l’aide d’une synthèse des principaux travaux sur la musique de film, de télévision et de jeu vidéo. Le deuxième chapitre interroge la notion de référence dans le contexte des usages répétés d’une même chanson populaire. Le concept d’interférence musicale est proposé à partir de différentes déclinaisons du terme « interférence » issues des travaux de Michel Serres, Sébastien Babeux et Philip Tagg. Les assises théoriques sont appliquées à l’analyse des trajectoires médiatiques respectives de deux chansons aux chapitres trois et quatre. La figure du réseau est finalement déployée afin d’illustrer la complexité des relations entre les œuvres intégrant une même chanson à leur mise en scène.

Backtracks: a devised performance

Backtracks aimed to investigate critical relationships between audio-visual technologies and live performance, emphasising technologies producing sound, contrasted with non-amplified bodily sound. Drawing on methodologies for studying avant garde theatre, live performance and the performing body, it was informed by work in critical and cultural theory by, for example, Steven Connor and Jonathan Rée, on the body's experience and interpretation of sound. The performance explored how shifting national boundaries, mobile workforces, complex family relationships, cultural pluralities and possibilities for bodily transformation have compelled a re-evaluation of what it means to feel 'at home' in modernity. Using montages of live and mediated images, disrupted narratives and sound, it evoked destablised identities which characterise contemporary lived experience, and enacted the displacement of certainties provided by family and nation, community and locality, body and selfhood. Homer's Odyssey framed the performance: elements could be traced in the mise-en-scène; in the physical presence of Athene, the narrator and Penelope weaving mementoes from the past into her loom; and in voice-overs from Homer's work. The performance drew on personal experiences and improvisations, structured around notions of journey. It presented incomplete narratives, memories, repressed anxieties and dreams through different combinations of sounds, music, mediated images, movement, voice and bodily sound. The theme of travel was intensified by performers carrying suitcases and umbrellas, by soundtracks incorporating travel effects, and by the distorted video images of forms of transport playing across 'screens' which proliferated across the space (sails, umbrellas, the loom, actors' bodies). The performance experimented with giving sound and silence performative dimensions, including presenting sound in visual and imagistic ways, for example by using signs from deaf sign language. Through-composed soundtracks of live and recorded song, music, voice-over, and noise exploited the viscerality of sound and disrupted cognitive interpretation by phenomenological, somatic experience, thereby displacing the impulse for closure/destination/home.

Cartografemas: fragmentos autobiográficos de um artista-professor

Esta pesquisa, de cunho narrativo autobiográfico, aborda a trajetória de vida do artista plástico e professor Jorge Eiró. A pesquisa propõe-se a investigar as articulações entre as atividades desempenhadas e suas implicações em seu processo de formação. Incorpora como referência plástica e conceitual a poética visual de sua obra associada às suas afinidades estéticas e culturais enquanto produção de subjetividade. Neste movimento, a composição da escritura narrativa configura-se em uma cartografia e assume o sentido de função, segundo o conceito de Gilles Deleuze e Félix Guattari, alinhando-se numa perspectiva teórica pós-estruturalista. Nessa concepção, sujeito e objeto da cartografia autobiográfica convertem-se em superjecto. A narrativa transcorre em relatos fragmentados, dispersos mas articulados entre si, elaborados na forma de biografema, segundo o conceito de Roland Barthes. A função da cartografia articulada com a forma do biografema constituem o amálgama narrativo de cartografemas. A escritura é atravessada por referências culturais, musicais (trilha sonora) e literárias (lira literária) da memória afetiva do autor. A problematização consiste no modo como se articulam e se refratam os componentes autobiográficos, enunciados nos biografemas. De metodologia bibliográfica, esta pesquisa apresenta como categorias fundamentais a autobiografia em educação, a arte e a docência em arte. Na composição deste autorretrato, o quadro teórico-metodológico da cartografia é traçado por linhas cardeais de referência dos seguintes autores: Nietzsche, Deleuze e Guattari conceituam a cartografia numa perspectiva pós estruturalista; Barthes concebe a escritura narrativa na forma de biografemas; Larrosa e Rolnik alinham as coordenadas cartográficas para uma autobiografia em educação; Argan e Derdyk desenham o campo da história e filosofia da arte; finalmente, Corazza e Silva colorem a composição com a filosofia da diferença em educação e a poética de uma escrita-artista.

Towards Automatic Identification of Discourse Markers in Dialogs: the Case of 'Like'

This article discusses the detection of discourse markers (DM) in dialog transcriptions, by human annotators and by automated means. After a theoretical discussion of the definition of DMs and their relevance to natural language processing, we focus on the role of like as a DM. Results from experiments with human annotators show that detection of DMs is a difficult but reliable task, which requires prosodic information from soundtracks. Then, several types of features are defined for automatic disambiguation of like: collocations, part-of-speech tags and duration-based features. Decision-tree learning shows that for like, nearly 70% precision can be reached, with near 100% recall, mainly using collocation filters. Similar results hold for well, with about 91% precision at 100% recall.

Transductor óptico-sonoro basado en procesado de imagen

En este proyecto se aborda la transducción óptico-sonora utilizando métodos de tratamiento digital de imagen. Para llevar a cabo el proyecto se consideran únicamente métodos de bajo presupuesto, por lo que para realizar todo el proceso de conversión óptico-sonora se utilizan un ordenador y un escáner doméstico. Como el principal objetivo del proyecto es comprobar si es viable utilizar el tratamiento digital de imagen como conversor no se ha contemplado la utilización de equipamiento profesional. La utilidad de este proyecto está en la restauración del sonido de material fílmico con importantes degradaciones, tales que no sea posible su reproducción en un proyector. Con el prototipo que se propone, realizado con el software de programación Matlab, se consigue digitalizar el audio analógico de las películas en malas condiciones ya que la captura de audio se efectúa de manera óptica sobre las bandas sonoras. Lo conseguido en este proyecto cobra especial importancia si se tiene en cuenta la cantidad de material cinematográfico que hay en películas de celulosa. La conservación de dicho material requiere unas condiciones de almacenamiento muy específicas para que el soporte no se vea afectado, pero con el paso del tiempo es habitual que las bobinas de película presenten deformaciones o incluso ruptura. Aplicando métodos de tratamiento digital de imagen es posible restaurar el audio de fragmentos de película que no puedan ser expuestos a la tensión producida por los rodillos de los proyectores, incluso es posible recuperar el audio de fotogramas concretos ya que la digitalización del audio se realiza capturando la imagen de la forma de onda. Por ello, el procedimiento seguido para digitalizar la película debe ser poco intrusivo para garantizar la conservación del soporte fílmico. Cabe destacar que en este proyecto se ha realizado la conversión óptico-sonora sobre las bandas de sonido analógicas de área variable presentes en la película, pero el procedimiento es aplicable también a las bandas de área variable realizando modificaciones en el prototipo. Esto último queda fuera del objetivo de este proyecto, pero puede ser un trabajo futuro. ABSTRACT This project addresses optical to sound conversion using digital image processing methods. To carry out the project are considered only low-budget methods , so for all optical to sound conversion process using a computer and a home scanner . As the main application of this project is to test the feasibility of using the digital image processing as a converter does not contemplate the use of professional equipment. The main objective of this project is the restoration of sound film material with significant impairments , such is not possible playback on a projector. With the proposed prototype , made with Matlab programming software , you get digitize analog audio bad movies because the audio capture is performed optically on the soundtracks. The achievements in this project is especially important if you consider the amount of film material is in cellulose films . The preservation of such material requires a very specific storage conditions to which the support is not affected , but over time it is common for film reels presenting deformations or even rupture. Applying methods of digital image processing is possible to restore the audio from movie clips that can not be exposed to the tension produced by the rollers of the projectors , it is even possible to retrieve specific frames audio and audio that digitization is done by capturing the image of the waveform. Therefore, the procedure used to digitize the film should be bit intrusive to ensure the conservation of the film medium. Note that in this project was carried out optical to sound conversion on analog variable area soundtracks present in the film, but the procedure is applicable to variable-area bands making changes to the prototype. The latter is beyond the scope of this project, but can be a future work.

An experimental study on Aerobic Gymnastic: performance analysis as an effective evaluation for technique and teaching of motor gestures

Aerobic Gymnastic is the ability to perform complex movements produced by the traditional aerobic exercises, in a continuous manner, with high intensity, perfectly integrated with soundtracks. This sport is performed in an aerobic/anaerobic lactacid condition and expects the execution of complex movements produced by the traditional aerobic exercises integrated with difficulty elements performed with a high technical level. An inaccuracy about this sport is related to the name itself “aerobic” because Aerobic Gymnastic does not use just the aerobic work during the competition, due to the fact that the exercises last among 1’30” and 1’45” at high rhythm. Agonistic Aerobics exploit the basic movements of amateur Aerobics and its coordination schemes, even though the agonistic Aerobics is so much intense than the amateur Aerobics to need a completely different mix of energetic mechanisms. Due to the complexity and the speed with which you perform the technical elements of Aerobic Gymnastic, the introduction of video analysis is essential for a qualitative and quantitative evaluation of athletes’ performance during the training. The performance analysis can allow the accurate analysis and explanation of the evolution and dynamics of a historical phenomenon and motor sports. The notational analysis is used by technicians to have an objective analysis of performance. Tactics, technique and individual movements can be analyzed to help coaches and athletes to re-evaluate their performance and gain advantage during the competition. The purpose of the following experimental work will be a starting point for analyzing the performance of the athletes in an objective way, not only during competitions, but especially during the phases of training. It is, therefore, advisable to introduce the video analysis and notational analysis for more quantitative and qualitative examination of technical movements. The goal is to lead to an improvement of the technique of the athlete and the teaching of the coach.
