Abstract

a presente tecnologia refere-se a um aparelho e a um método para processamento de áudio, e a um programa, que possibilita a reprodução de áudio com maior eficiência. em uma unidade de síntese da função de transferência relacionada à cabeça da presente tecnologia, uma matriz da função de transferência relacionada à cabeça diagonalizada é pré-contida. a unidade de síntese da função de transferência relacionada à cabeça sintetiza um sinal de entrada em um domínio harmônico anular para reprodução de áudio e a matriz da função de transferência relacionada à cabeça diagonalizada pré-contida. uma unidade de transformação inversa harmônica anular gera um sinal de acionamento do fone de ouvido em um domínio de frequência temporal pela realização, com base em uma função harmônica anular, da transformação inversa harmônica anular em um sinal resultante da síntese realizada pela unidade de síntese da função de transferência relacionada à cabeça. a presente tecnologia pode ser aplicada em um aparelho para processamento de áudio.
