Abstract
La presente invención se refiere a la transposición de señales en el dominio del tiempo y/o la frecuencia, y en particular a la codificación de señales de audio. Más concretamente, la presente invención se refiere a métodos de reconstrucción de alta frecuencia (HFR), incluyendo un transponedor armónico en el dominio de la frecuencia. Se describe un método y un sistema para generar una señal de salida transpuesta a partir de una señal de entrada utilizando un factor de transposición T. El sistema comprende una ventana de análisis de longitud L a , que extrae un fotograma de la señal de entrada, y una unidad de transformación de análisis de orden M que transforma las muestras en M coeficientes complejos. M es una función del factor de transposición T. El sistema comprende además una unidad de procesamiento no lineal que modifica la fase de los coeficientes complejos utilizando el factor de transposición T, una unidad de transformación de síntesis de orden M que transforma los coeficientes modificados en M muestras modificadas, y una ventana de síntesis de longitud L s , que genera un fotograma de la señal de salida.
