Abstract
Un método de extensión armónica de ancho de banda de señales de audio que incluye separar, en un dispositivo, una señal de audio de entrada al menos en una señal de banda baja y una señal de banda alta. La señal de banda baja corresponde a un rango de frecuencia de banda baja y la señal de banda alta corresponde a un rango de frecuencia de banda alta. El método también incluye seleccionar una función de procesamiento no lineal de una pluralidad de funciones de procesamiento no lineales. El método incluye además generar una primera señal extendida con base en la señal de banda baja y la función de procesamiento no lineal. El método también incluye generar al menos un parámetro de ajuste con base en la primera señal extendida, la señal de banda alta, o ambas.
