Abstract

Un codificador de audio para producir una información de audio codificada sobre la base de una información de audio de entrada comprende un proveedor de información de extensión de ancho de banda configurado para otorgar información de extensión de ancho de banda empleando una resolución temporal variable y un detector configurado para detectar una activación de un fricativo o africado. El codificador de audio está configurado para ajustar una resolución temporal utilizada por el proveedor de información de extensión de ancho de banda de tal manera que se genere información de extensión de ancho de banda con una resolución temporal incrementada por lo menos durante un período de tiempo predeterminado antes del momento en el cual se detecta la activación de un fricativo o africado y durante un período de tiempo predeterminado posterior al momento en el cual se detecta la activación del fricativo o africado. Por otro lado o además, la información de extensión de ancho de banda está provista de una resolución temporal incrementada en respuesta a la detección de una desactivación de un fricativo o africado. Codificadores de audio y métodos que utilizan un concepto correspondiente.
