Abstract
um sistema de som multicanal (mcs) apresenta calibração inteligente (por exemplo, de cancelamento de eco acústico (aec)) para uso em ambientes acústicos dinâmicos. um subsistema de sensor é utilizado para detectar e identificar mudanças no ambiente acústico e determinar uma ?cena? correspondendo às características acústicas resultantes para aquele ambiente. esta cena detectada é comparada com cenas predeterminadas correspondendo ao ambiente acústico. cada cena predeterminada tem uma configuração de filtro pré-ajustada correspondente para desempenho aec ótimo. com base nos resultados da comparação, a configuração de filtro pré-ajustada correspondendo à cena predeterminada que mais próximo se combina com a cena detectada é utilizada pelo subsistema aec do sistema de som multicanal.
