Abstract

En algunas modalidades, los métodos de virtualización para generar una señal binaural en respuesta a canales de una señal de audio multicanal, que aplican una respuesta impulsiva binaural de sala (BRIR) a cada canal que incluye al utilizar al menos una red de retardo realimentada (FDN) para aplicar una reverberación tardía común a una mezcla de audio de los canales. En algunas modalidades, los canales de la señal de entrada son procesados en una primera ruta de procesamiento para aplicar a cada canal una porción de respuesta directa irreflexión temprana de una BRIR de un solo canal para el canal, y la mezcla de audio de los canales se procesa en una segunda ruta de procesamiento que incluye al menos una FDN que aplica la reverberación tardía común. Generalmente, la reverberación tardía común emula macro atributos colectivos de porciones de reverberación tardía de al menos algunas de las BRIRs de un solo canal. Otros aspectos son virtualizadores de auriculares configurados para llevar a cabo cualquier modalidad del método.
