Abstract

El calculador de contorno de distorsion de tiempo para uso en un decodificador de senal de audio para proveer una representacion de senal de audio decodificada sobre la base de una representacion de senal de audio codificada está configurado para recibir una informacion de la relacion de distorsion codificada, para derivar una secuencia de valores de relacion de distorsion a partir de la informacion de la relacion de distorsion codificada, y obtener valores de nodo de contorno de distorsion partiendo de un valor de inicio de contorno de distorsion de tiempo. Las relaciones entre los valores de nodo de contorno de distorsion de tiempo y el valor de inicio de contorno de distorsion de tiempo asociado con un nodo de inicio de contorno de distorsion de tiempo se determinan por los valores de relacion de distorsion. El calculador de contorno de distorsion de tiempo está configurado para computar un valor de nodo de contorno de distorsion de tiempo de un nodo de contorno de distorsion de tiempo dado, el cual está espaciado del nodo de inicio de contorno de distorsion de tiempo por un nodo de contorno de distorsion de tiempo intermedio sobre la base de la formacion de un producto que comprende una relacion entre el valor de nodo de contorno de dispersion de tiempo del nodo de contorno de distorsion de tiempo intermedio y el valor de inicio de contorno de distorsion de tiempo y una relacion entre el valor de nodo de contorno de dispersion de tiempo del nodo de contorno de distorsion de tiempo dado y el valor de nodo de contorno de distorsion de tiempo del nodo de contorno de distorsion de tiempo intermedio como factores.
