Abstract
Un renderizador de audio comprende un receptor (801) para recibir datos de entrada que comprenden datos de la parte temprana indicativos de una parte temprana de una función de transferencia biaural relacionada con la cabeza; datos de reverberación indicativos de una parte de reverberación de la función de transferencia; y una indicación de sincronización indicativa de un desplazamiento del tiempo entre la parte temprana y la parte de reverberación. Un circuito de parte temprana (803) genera un componente de audio mediante la aplicación de un procesamiento biaural a una señal de audio en donde el procesamiento depende de los datos de la parte temprana. Un reverberador (807) genera un segundo componente de audio mediante la aplicación de un procesamiento de reverberación a la señal de audio en donde el procesamiento de la reverberación depende de los datos de reverberación. Un combinador (809) genera una señal de una señal estéreo biaural combinando los dos componentes de audio. La temporización relativa de los componentes de audio se ajusta con base en la indicación de sincronización por medio de un sincronizador (805) que puede ser específicamente un retardo.
