Abstract
La presente descripción proporciona métodos, dispositivos y productos de programa de computadora para codificar y descodificar un vector de parámetros en un sistema de codificación de audio. La descripción se relaciona además con un método y aparato para reconstruir un objeto de audio en un sistema de descodificación de audio. De acuerdo con la descripción, un enfoque diferencial por módulo para codificar y descodificar un vector de una cantidad no periódica puede mejorar la eficiencia de codificación y proporcionar codificadores y descodificadores con menos requerimientos de memoria. Además, se proporciona un método eficiente para codificar y descodificar una matriz dispersa.
