Abstract
Se proporciona un decodificador para generar una señal de salida de audio que comprende uno o más canales de salida de audio. El decodificador comprende una interfaz (110) de recepción para recibir una señal de entrada de audio que comprende una pluralidad de señales de objetos de audio, para recibir información de sonoridad sobre las señales de objetos de audio, y para recibir información de presentación que indica si una o más de las señales de objetos de audio debe ser, o no, amplificada o atenuada. Además, el decodificador comprende un procesador (120) de señales para generar uno o más canales de salida de audio de la señal de salida de audio. El procesador (120) de señales se configura para determinar un valor de compensación de sonoridad dependiendo de la información de sonoridad y dependiendo de la información de presentación. Además, el procesador (120) de señales se configura para generar uno o más canales de salida de audio de la señal de salida de audio a partir de la señal de entrada de audio dependiendo de la información de presentación y dependiendo del valor de compensación de sonoridad. Además, se proporciona un codificador.
