Abstract

COMBINAçãO DE SINAIS DE áUDIO USANDO UMA ANáLISE DE CENA AUDITIVA. a invenção refere-se a um processo para combinar canais de áudio que combina os canais de áudio para produzir um canal de áudio combinado e aplicar dinamicamente um ou mais ajustes de tempo, fase, e amplitude ou potência aos canais, ao canal combinado, ou a ambos os canais e o canal combinado. Um ou mais dos ajustes são controlados pelo menos parcialmente por uma medida de eventos auditivos em um ou mais dos canais e/ou no canal combinado. Aplicações incluem a apresentação do áudio de múltiplos canais em cinemas e veículos. Não apenas métodos, mas também implementações em programas de computador e implementações em aparelhos correspondentes estão incluídas.
