Abstract

suavização de metadados de áudio. o método implementado por computador revelado para suavizar lacunas de áudio usando metadados adaptáveis identifica um segmento de áudio inicial e um segmento de áudio subsequente que se segue ao segmento de áudio inicial. o método acessa um primeiro conjunto de metadados que corresponde a um último quadro de áudio do segmento de áudio inicial e acessa um segundo conjunto de metadados que corresponde ao primeiro quadro de áudio do segmento de áudio subsequente. os primeiro e segundo conjuntos de metadados incluem informação de característica de áudio para os dois segmentos de áudio. o método então gera um novo conjunto de metadados que é baseado em ambos os conjuntos de características de áudio. o método adicionalmente insere um novo quadro de áudio entre o último quadro de áudio do segmento de áudio inicial e o primeiro quadro de áudio do segmento de áudio subsequente e aplica o novo conjunto de metadados ao novo quadro de áudio. vários outros métodos, sistemas e meios legíveis por computador também são revelados.
