Abstract
esta tecnologia refere-se a um dispositivo e método de codificação, a um dispositivo e método de decodificação e a um programa que habilitam que som de qualidade mais alta seja obtido. uma unidade de decodificação do sinal de áudio decodifica os dados de áudio codificados para obter um sinal de áudio de cada um dos objetos. uma unidade de decodificação de metadados decodifica os metadados codificados para obter múltiplas peças de metadados para cada quadro do sinal de áudio de cada um dos objetos. uma unidade de cálculo de ganho calcula o ganho de vbap do sinal de áudio de cada um dos objetos, alto-falante por alto-falante, com base nos metadados. uma unidade de geração do sinal de áudio multiplica o sinal de áudio de cada um dos objetos pelo ganho de vbap, alto-falante por alto-falante, e adiciona os resultados da multiplicação para, desse modo, gerar um sinal de áudio a ser suprido para cada alto-falante. esta tecnologia é aplicável em um dispositivo de decodificação.
