Abstract

controle de cancelamento de eco acústico para dispositivos de áudio distribuído. um método de processamento de áudio pode envolver o recebimento de sinais de saída de cada microfone de uma pluralidade de microfones em um ambiente de áudio, os sinais de saída correspondendo a uma expressão atual de uma pessoa e determinar, com base nos sinais de saída, um ou mais aspectos das informações de contexto relacionadas à pessoa, incluindo uma proximidade atual estimada da pessoa a um ou mais locais de microfone. o método pode envolver selecionar dois ou mais dispositivos de áudio equipados com caixa de som com base, pelo menos em parte, em um ou mais aspectos das informações de contexto, determinar um ou mais tipos de alterações de processamento de áudio para aplicar aos dados de áudio sendo renderizados para sinais de alimentação de caixa de som para os dispositivos de áudio e fazer com que um ou mais tipos de alterações de processamento de áudio sejam aplicadas. em alguns exemplos, as alterações no processamento de áudio têm o efeito de aumentar a relação fala para eco em um ou mais microfones.
