Abstract

resumo patente de invenção: "sistema e método para otimizar o nível de intensidade do som e a faixa dinâmica através de dispositivos de reprodução diferentes". a presente invenção refere-se a um método e um sistema para receber, em um fluxo de bits, metadados associados com dados de áudio, e analisar os metadados para determinar se um parâmetro de nível de intensidade do som para um primeiro grupo de dispositivos de áudio de reprodução está disponível no fluxo de bits. em resposta à determinação que os parâmetros estão presentes para o primeiro grupo, o sistema usa os parâmetros e os dados de áudio para definir o áudio. em resposta à determinação que os parâmetros de nível de intensidade do som não estão presentes para o primeiro grupo, o sistema analisa uma ou mais características do primeiro grupo, e determina o parâmetro com base em uma ou mais características. 1/1
