Abstract

La presente tecnología se refiere a un dispositivo y método de procesamiento de señales, a un dispositivo y método de aprendizaje y a un programa que hacen posible realizar una reproducción de audio de calidad alta incluso con un dispositivo de bajo coste. Este dispositivo de procesamiento de señales comprende: una unidad de procesamiento de descodificación que desmultiplexa un flujo de bits de entrada en una primera señal de audio, metadatos de la primera señal de audio y primera información de banda de alta frecuencia para el ensanchamiento de banda; y una unidad de ensanchamiento de banda que realiza un procesamiento de ensanchamiento de banda en función de una segunda señal de audio obtenida realizando un procesamiento de señales en función de la primera señal de audio y los metadatos, y una segunda información de banda de alta frecuencia generada en función de la primera información de banda de alta frecuencia, generando de ese modo una señal de audio de salida. La presente tecnología es aplicable a los teléfonos inteligentes.
