Abstract

Un aparato para codificar una pluralidad de objetos de audio, que comprende: una calculadora de parámetros de objeto (100) configurada para calcular, para uno o más intervalos de frecuencia de una pluralidad de intervalos de frecuencia relacionados con un intervalo de tiempo, datos de parámetros para al menos dos objetos de audio relevantes, en donde un número de los al menos dos objetos de audio relevantes es menor que un número total de la pluralidad de objetos de audio, y una interfaz de salida (200) para emitir una señal de audio codificada que comprende información sobre los datos de parámetros para los por lo menos dos objetos de audio relevantes para los uno o más intervalos de frecuencia.
