Abstract

DISPOSITIVOS E MÉTODOS DE PROCESSAMENTO DE SINAL E DE APRENDIZADO, E, PROGRAMA. A presente tecnologia se refere a um dispositivo e método de processamento de sinal, um dispositivo e método de aprendizado e um programa que tornam possível executar a reprodução de áudio com alta qualidade, mesmo um dispositivo barato. Este dispositivo de processamento de sinal compreende: uma unidade de processamento de decodificação que demultiplexa um fluxo de bits de entrada em um primeiro sinal de áudio, metadados do primeiro sinal de áudio e primeira informação de banda de alta frequência para expandir uma banda; e uma unidade de expansão de banda que executa processamento de expansão de banda com base em um segundo sinal de áudio obtido ao executar processamento de sinal com base no primeiro sinal de saída e nos metadados, e segunda informação de banda de alta frequência gerada com base na primeira informação de banda de alta frequência, gerando, desse modo, um sinal de áudio de saída. A tecnologia atual é aplicável a smartphones.
