Abstract
MÉTODO E MECANISMO PARA CONVERSÃO DE UM SINAL DE ÁUDIO DE MULTICANAL EM UM SINAL DE ÁUDIO DE DOIS CANAIS. É descrito um método para conversão de um sinal de áudio de n-canal (L, R, Ls, Rs) em um sinal de áudio de dois canais (Ro, Lo), onde n (Maior igual)4 e número inteiro, compreendendo a etapa de gerar qualquer um dos sinais de áudio de dois canais, direito (Ro) ou esquerdo (Lo), por uma combinação de: componentes de sinal frontal (R, L) e traseiro (Rs, Ls) do sinal de áudio de n-canal do mesmo lado (direito ou esquerdo) , e um componente de sinal frontal (L, R) do sinal de áudio de n-canal do outro lado (esquerdo ou direito), e um termo dependente de n.
