Abstract

Se presenta un decodificador 110 para decodificar una señal de audio 32. El decodificador 110 comprende un primer generador de espectros objetivo 65a para generar un espectro objetivo 85a correspondiente al primer intervalo de tiempo de una señal de sub-banda de la señal de audio 32 utilizando primeros datos de corrección 295a. Un primer corrector de fase 70a corrige una fase 45 de la señal de sub-banda en el primer intervalo de tiempo de la señal de audio 32 que se determina con un algoritmo de corrección de fase, donde la corrección se realiza reduciendo una diferencia entre una medida de la señal de sub-banda en el primer intervalo de tiempo de la señal de audio 32 y el espectro objetivo 85a. Una calculadora de señales de sub-bandas de audio 350 calcula la señal de sub-banda de audio 355 correspondiente al primer intervalo de tiempo utilizando una fase corregida 91a para el intervalo de tiempo y para calcular señales de sub-bandas de audio 355 correspondientes a un segundo intervalo de tiempo diferente del primer intervalo de tiempo empleando la medida de la señal de sub-banda 85a en el segundo intervalo de tiempo o utilizando un cálculo de fase corregida de acuerdo con otro algoritmo de corrección de fase diferente del algoritmo de corrección de fase.
