Abstract

Un procesador de audio para proporcionar una pluralidad de señales de altavoz, o alimentaciones de altavoz, sobre la base de una pluralidad de señales de entrada, como señales de canal y/o señales de objeto. El procesador de audio está configurado para obtener información sobre la posición de un oyente. El procesador de audio está configurado además para obtener información sobre la posición de una pluralidad de altavoces, o transductores de sonido, que pueden, por ejemplo, colocarse dentro de la misma contención, por ejemplo, una barra de sonido. El procesador de audio está configurado además para seleccionar uno o más altavoces para una representación de los objetos y/o de los objetos de canal y/o de las señales adaptadas, derivadas de las señales de entrada, como señales de canal u objetos de canal, o como mezcla ascendente o descendente de señales. La selección del uno o los varios altavoces depende de la información sobre la posición del oyente, de la información sobre las posiciones de los altavoces y tiene en cuenta información sobre uno o más obstáculos acústicos. En otras palabras, el procesador de audio decide qué altavoces deben usarse en la representación de los diferentes objetos de canal o señales adaptadas, teniendo en cuenta, por ejemplo, la atenuación del sonido entre el altavoz y el oyente o un alargamiento de la vía acústica entre el altavoz y el oyente debido a las propiedades del obstáculo. El procesador de señal de audio está configurado además para representar los objetos y/o los objetos de canal y/o las señales adaptadas derivadas de las señales de entrada, en función de la información sobre la posición del oyente y en función de la información sobre las posiciones de los altavoces, para obtener las señales de altavoces, de modo que un sonido representado siga al oyente.
