Abstract
Un aparato para procesar una representación de campo de sonido relacionada con un punto de referencia definido o una orientación de escucha definida para la representación de campo de sonido, comprende: un procesador de campo de sonido para procesar la representación de campo de sonido utilizando una desviación de una posición de escucha diana desde el punto de referencia definido o de una orientación de escucha diana desde la orientación de escucha definida, de manera que se obtiene una descripción de campo de sonido procesada, en donde la descripción de campo de sonido procesada cuando se renderiza, proporciona una impresión de que la representación de campo de sonido en la posición de escucha diana es diferente del punto de referencia definido o de que la orientación de escucha diana es diferente de la orientación de escucha definida, o para procesar la representación de campo de sonido utilizando un filtro espacial de manera que se obtenga la descripción de campo de sonido procesada, en donde la descripción de campo de sonido procesada, cuando se renderiza, proporciona una impresión de una descripción de campo de sonido, filtrada espacialmente, en donde el procesador del campo de sonido (1000) está configurado para procesar la representación de campo de sonido de manera que la desviación o el filtro espacial (1030) se aplique en un dominio de transformada espacial que tiene asociada una regla de transformada hacia delante (1021) y una regla de transformada hacia atrás (1051).
