Abstract
Aparato y método para generar valores de sub-banda de audio y aparato y método para generar muestras de audio con dominio de tiempo. Una realizacion de un aparato (100) para generar valores de sub-banda de audio en canales de sub-banda de audio comprende un generador de ventanas (windower) de análisis (110) para poner en ventana un marco (120) de muestras de entrada de audio del dominio de tiempo que se encuentran en una secuencia de tiempo que se extiende desde una muestra inicial hasta una muestra posterior usando una funcion de ventana de análisis (190) que comprende una secuencia de coeficientes de ventana para obtener muestras ordenadas en ventanas. La funcion de la ventana de análisis comprende un primer numero de coeficientes de ventana derivados de una funcion de ventana más grande que comprende una secuencia de un segundo numero más grande de coeficientes de ventana, donde los coeficientes de ventana de la funcion de ventana derivan de una interpolacion de coeficientes de ventana de una funcion de ventana más grande. El aparato (100) además comprende una calculadora (170) para calcular los valores de sub-banda de audio usando las muestras ordenadas en ventanas.
