Abstract
Se provee un aparato para generar una envolvente de señal de audio a partir de uno o más valores de codificación. El aparato comprende una interfaz de entrada (1610) para recibir el uno o más valores de codificación y un generador de envolvente (1620) para generar la envolvente de la señal de audio, dependiendo de los uno o más valores de codificación. El generador de envolvente (1620) está configurado para generar una función de agregación dependiendo de los uno o más valores de codificación, en donde la función de agregación comprende una pluralidad de puntos de agregación, en donde cada uno de los puntos de agregación comprende un valor de argumento y un valor de agregación, en donde la función de agregación aumenta monotónicamente y en donde cada uno de los uno o más valores de codificación indica por lo menos uno de un valor de argumento y un valor de agregación de uno de los puntos de agregación de la función de agregación. Además, el generador de envolvente (1620) está configurado para generar la envolvente de la señal de audio, de tal manera que la envolvente de la señal de audio comprende una pluralidad de puntos de envolvente, en donde cada uno de los puntos de envolvente comprende un valor de argumento y un valor de envolvente y en donde un punto de envolvente de la envolvente de la señal de audio es asignado a cada uno de los puntos de agregación de la función de agregación, de tal manera que el valor de argumento de tal punto de envolvente es igual al valor del argumento de tal punto de agregación. Además, el generador de envolvente (1620) está configurado para generar la envolvente de la señal de audio, de tal manera que el valor de envolvente de cada uno de los puntos de envolvente de la envolvente de la señal de audio depende del valor de agregación de por lo menos un punto de agregación de la función de agregación.
