UN MÉTODO DE VISUALIZACIÓN DE SONIDO BASADO EN LAS MUESTRAS OBTENIDAS DE SU DIGITALIZACIÓN EN TIEMPO REAL
[EN] Abstract In the tradition of Visual Music, we propose a method of sound visualization based on digital samples of sound obtained as a result of digitization for an environment in which music and image generation unfold in real time, being ideal for audiovisual live events. If we consider that:...

| Sumario: | [EN] Abstract In the tradition of Visual Music, we propose a method of sound visualization based on digital samples of sound obtained as a result of digitization for an environment in which music and image generation unfold in real time, being ideal for audiovisual live events. If we consider that: a digitized sound is just a set of numbers arranged in time representing the intensity of the signal at each instant of time, and an image at a given moment it is no more than a set of pixels, whose value is a number representing the l ight intensity at a point, in the case of monochrome image a unique number and if chromatic number for each color channel. The proposed method takes the numerical values of the sound samples and spatially located generating a moving image. Depending on the method used for spatial positioning of the samples, the number of samples used sound (present and even past) and the number of sound sources to integrate, we get different display algorithms families with own aesthetic characteristics. This work establishes the necessary measures to address the sound visualization based on samples and presents a case study, performed with an application in the Java programming language bases. |
