Abstract

Se describe un método para procesar información de posición indicativa de una posición de objeto de un objeto de audio, en donde la posición de objeto es utilizable para representar el objeto de audio, que comprende: obtener información de orientación de oyente indicativa de una orientación de la cabeza de un oyente; obtener información de desplazamiento de oyente indicativa de un desplazamiento de la cabeza del oyente; determinar la posición de objeto a partir de la información de posición; modificar la posición de objeto con base en la información de desplazamiento de oyente mediante la aplicación de una traslación a la posición de objeto; y modificar además la posición de objeto modificada con base en la información de orientación de oyente. Se describe además un aparato correspondiente para procesar información de posición indicativa de una posición de objeto de un objeto de audio, en donde la posición de objeto se puede usar para representar el objeto de audio.
