Abstract
Se revela un método para decodificar un flujo de bits de audio codificado. El método incluye recibir el flujo de bits de audio codificado y decodificar los datos de audio para generar una señal de audio de banda baja decodificada. El método incluye además extraer metadatos de reconstrucción de alta frecuencia y filtrar la señal de audio de banda baja decodificada con un banco de filtros de análisis para generar una señal de audio de banda baja filtrada. El método también incluye extraer una bandera que indica si se debe realizar traslación espectral o transposición armónica en los datos de audio y regenerar una porción de banda alta de la señal de audio utilizando la señal de audio de banda baja filtrada y los metadatos de reconstrucción de alta frecuencia de acuerdo con la bandera
