Accesibilidad en Pure Data para músicos con discapacidad visual: una estrategia de paisaje sonoro en tiempo real
Contenido principal del artículo
Resumen
Introducción: Pure Data (Pd) es un lenguaje de programación predominantemente visual ampliamente utilizado por músicos en los procesos de composiciones e interpretaciones musicales que implican síntesis sonora. Esta característica visual implica una accesibilidad deficiente para un músico con discapacidad visual (MDV), ya que los lectores de pantalla no permiten reconocer y/o manipular los elementos del lenguaje. Objetivos: Este trabajo pretende presentar una estrategia inclusiva que permita a los MDV interactuar con otros músicos en actuaciones en directo. Métodos: Un músico vidente programó un guión de Pd compuesto por cinco parches. Los interruptores y potenciómetros de un controlador MIDI se ajustaban a los elementos del guión, activando y modulando los parámetros de los clips de sonido. El MDV utiliza el lector de pantalla para acceder a Pd, abrir el código programado, configurar el controlador MIDI y habilitar la salida de audio. El MDV ejecuta la actuación. Resultados: El resultado fue una actuación de paisaje sonoro en directo que presentaba similitudes en la manipulación del controlador MIDI con la del músico vidente. Conclusión: Estas estrategias permitieron a un MDV actuar de autónomamente en tiempo real utilizando parches de Pd, favoreciendo la interacción con músicos videntes y ampliando la accesibilidad.
