Abstract

El presente documento se relaciona con la codificación y decodificación de audio. En particular, el presente documento se relaciona con esquemas de codificación de audio que utilizan métodos de reconstrucción de alta frecuencia (HFR). Se describe un sistema configurado para determinar una tabla maestra de bandas de factor de escala de una señal de banda alta (105) de una señal de audio. La señal de banda alta (105) se ha de generar a partir de una señal de banda baja (101) de la señal de audio usando un esquema de reconstrucción de alta frecuencia (HFR). La tabla maestra de bandas de factor de escala es indicativa de la resolución de frecuencia de una envolvente espectral de la señal de banda alta (105).
