Abstract

Se mejora la calidad del llenado con ruido del espectro de una señal de audio con respecto al espectro llenado con ruido de manera que la reproducción de la señal de audio llenada con ruido sea menos molesta, mediante la ejecución del llenado con ruido de manera dependiente de la tonalidad de la señal de audio.
