This coincided with Professor [Amar] Bose mov- ing out of some space on the third floor of Building 26. He had stopped doing research at MIT at that point; he had been given what I think remains the only post of a full professor at MIT who teaches just one class and doesn’t do any research on campus. He moved out of his lab, and we promptly moved in because it had a nice acoustic treatment and was a much better environment for the new PDP-11. For the next twelve years, this was the area that the composers lived in. Lefford: What influenced your decision to build an all-digital experimental music studio? Did you draw from the experiences you had at other institutions? Vercoe: As a composer, I had no experiences in electronic music whatsoever in New Zealand where I did my undergraduate degrees.

    Interpretação em tempo real sobre material sonoro pré-gravado JOÃO PEDRO MARTINS MEALHA DOS SANTOS Mestrado em Multimédia da Universidade do Porto Dissertação realizada sob a orientação do Professor José Alberto Gomes da Universidade Católica Portuguesa - Escola das Artes Julho de 2014 2 Agradecimentos Em primeiro lugar quero agradecer aos meus pais, por todo o apoio e ajuda desde sempre. Ao orientador José Alberto Gomes, um agradecimento muito especial por toda a paciência e ajuda prestada nesta dissertação. Pelo apoio, incentivo, e ajuda à Sara Esteves, Inês Santos, Manuel Molarinho, Carlos Casaleiro, Luís Salgado e todos os outros amigos que apesar de se encontraram fisicamente ausentes, estão sempre presentes. A todos, muito obrigado! 3 Resumo Esta dissertação tem como foco principal a abordagem à interpretação em tempo real sobre material sonoro pré-gravado, num contexto performativo. Neste caso particular, material sonoro é entendido como música, que consiste numa pulsação regular e definida. O objetivo desta investigação é compreender os diferentes modelos de organização referentes a esse material e, consequentemente, apresentar uma solução em forma de uma aplicação orientada para a performance ao vivo intitulada Reap. Importa referir que o material sonoro utilizado no software aqui apresentado é composto por músicas inteiras, em oposição às pequenas amostras (samples) recorrentes em muitas aplicações já existentes. No desenvolvimento da aplicação foi adotada a análise estatística de descritores aplicada ao material sonoro pré-gravado, de maneira a retirar segmentos que permitem uma nova reorganização da informação sequencial originalmente contida numa música. Através da utilização de controladores de matriz com feedback visual, o arranjo e distribuição destes segmentos são alterados e reorganizados de forma mais simplificada.

  • Deubois New Edit
    Extension 5: Sound Text by R. Luke DuBois Excerpt from Processing: a programming handbook for visual designers and artists Casey Reas and Ben Fry The history of music is, in many ways, the history of technology. From developments in the writing and transcription of music (notation) to the design of spaces for the performance of music (acoustics) to the creation of musical instruments, composers and musicians have availed themselves of advances in human understanding to perfect and advance their professions. Unsurprisingly, therefore, we find that in the machine age these same people found themselves first in line to take advantage of the new techniques and possibilities offered by electricity, telecommunications, and, in the last century, digital computers to leverage all of these systems to create new and expressive forms of sonic art. Indeed, the development of phonography (the ability to reproduce sound mechanically) has, by itself, had such a transformative effect on aural culture that it seems inconceivable now to step back to an age where sound could emanate only from its original source. The ability to create, manipulate, and losslessly reproduce sound by digital means is having, at the time of this writing, an equally revolutionary effect on how we listen. As a result, the artist today working with sound has not only a huge array of tools to work with, but also a medium exceptionally well suited to technological experimentation. Composers adopted digital computers slowly as a creative tool because of their initial lack of real‐time responsiveness and intuitive interface. Although the first documented use of the computer to make music occurred in 1951 on the CSIRAC machine in Sydney, Australia, the genesis of most foundational technology in computer music as we know it today came when Max Mathews, a researcher at Bell Labs in the United States, developed a piece of software for the IBM 704 mainframe called MUSIC.
