Abstract

<B>DISPOSITIVO E MéTODO DE GERAçãO DE TONS, MEIO DE DISTRIBUIçãO E MEIO DE GRAVAçãO DE DADOS<D>, para eliminar o tempo do atraso desde quando um pedido é feito para reproduzir um tom prescrito até que ele seja realmente reproduzido, os dados de tom nos quais a parte do começo dos dados que geram um som de efeito consiste em dados não comprimidos e a parte restante consiste em dados comprimidos são armazenado em uma unidade de dados comprimidos. Uma unidade de processamento aritmético lê os dados armazenados na unidade de dados comprimidos e decide se esses dados são dados comprimidos. Se os dados forem dados não comprimidos, os dados são transferidos através do multiplexador (9) para o alto-falante (50) e reproduzidos. Enquanto os dados não comprimidos estão sendo reproduzidos, os dados restantes são transferidos para uma unidade de expansão, na qual o processamento de expansão é executado. Se os dados processados em expansão requererem um processamento de estágio posterior, eles são armazenados em uma unidade de dados pós-expansão, e se nenhum processamento desse tipo for requerido, eles são transferidos através de um multiplexador para um alto-falante e reproduzidos.
