Abstract

La descripción de la presente se relaciona generalmente con la captura, preprocesamiento acústico, codificación, decodificación y renderización de audio direccional de una escena de audio. En particular, se relaciona con un dispositivo adaptado para modificar una propiedad direccional de un audio direccional capturado en respuesta a datos espaciales de un sistema de micrófono que captura el audio direccional. La descripción se relaciona además con un dispositivo de renderización configurado para modificar una propiedad direccional de un audio direccional recibido en respuesta a datos espaciales recibidos.
