Abstract
Se proporciona un método y un aparato para determinar un modo de codificación para mejorar la calidad de una señal de audio reconstruida. Un método para determinar un modo de codificación incluye determinar uno de entre una pluralidad de modo de codificación incluye determinar uno de entre una pluralidad de modos de codificación que incluye un primer modo de codificación y un segundo modo de codificación como un modo de codificación inicial en relación con las características de una señal de audio y si existe un error en la determinación del modo de codificación inicial, generar un modo de codificación corregido al corregir el modo de codificación inicial a un tercer modo de codificación.
