Abstract

Un aparato de audio comprende un receptor (201) que recibe datos que describen una escena de audio. Los datos comprenden los datos de audio para un conjunto de elementos de audio que corresponden a fuentes de audio en la escena e incluyen además metadatos que comprenden al menos un primer indicador de propiedad de renderizado de audio para un primer elemento de audio del conjunto de elementos de audio. Un primer renderizador (205) renderiza elementos de audio al generar un primer conjunto de señales de audio para un conjunto de altavoces y un segundo renderizador (207) renderiza elementos de audio al generar un segundo conjunto de señales de audio para un auricular. Además, se dispone un selector (209) para seleccionar entre el primer renderizador y el segundo renderizador para renderizar al menos una primera parte del primer elemento de audio en respuesta al primer indicador de propiedad de renderizado de audio. El enfoque puede por ejemplo proporcionar experiencias de realidad virtual mejoradas usando el renderizado híbrido de altavoces y auriculares.
