De números a números: Visualización del sonido por métodos relacionales de muestreo en directo

Abstract

Development of a sound visualization method based on digital samples, these samples were obtained from the real-time scanning. The method is suitable for audiovisual live events within the tradition of Visual Music. If we consider that: a digitized sound is just a set of numbers arranged in time, and an image it is no more than a set of pixels ordained in space. The proposed method takes the numerical values of the sound samples and spatially located they, generating a moving image. Depending on the method used for the spatial positioning of the samples, the number of sound samples used, and the number of sound sources, we get different visualization algorithms families with own aesthetic characteristics. This work establishes the necessary measures to address the sound visualization based on samples, and presents case studies performed with a sofware developed in Java programming language.
