Abstract

Se pueden definir múltiples ubicaciones de fuentes virtuales para un volumen dentro del cual se pueden mover objetos de audio. Un proceso de configuración para renderizar datos de audio puede implicar recibir datos de ubicación de parlantes de reproducción y precomputar valores de ganancia para cada una de las fuentes virtuales de acuerdo con los datos de ubicación de los parlantes de reproducción y cada ubicación de las fuentes virtuales. Los valores de ganancia pueden almacenarse y usarse durante el "tiempo de ejecución", durante el cual los datos de reproducción de audio se renderizan para los parlantes del contexto de reproducción. Durante el tiempo de ejecución, para cada objeto de audio, se pueden computar contribuciones de ubicaciones de fuentes virtuales dentro de un área o volumen definidos por los datos de posición del objeto de audio y los datos de tamaño del objeto de audio. Se puede computar un conjunto de valores de ganancia para cada canal de salida del entorno de reproducción en función, al menos en parte, de las contribuciones computadas. Cada canal de salida puede corresponder al menos a un parlante de reproducción del entorno de reproducción.
