Abstract

resumo compressor digital para a compressão de um sinal de áudio a invenção se refere a um compressor digital (100) para a compressão de um sinal de áudio de entrada, compreendendo o compressor digital (100) um controle de ganho de compressão (101) para prover um parâmetro de ganho de compressão, um determinador do parâmetro de compressão (103) para determinar uma relação de compressão a partir do parâmetro de ganho de compressão, sendo o determinador de parâmetro de compressão (103) configurado para aplicar um peso ao parâmetro de ganho de compressão de um fator de ponderação predeterminado para ser obtida a relação de compressão, um gerador de sinal auxiliar (105) para a manipulação do sinal de áudio de entrada em função da relação de compressão para ser obtido um primeiro sinal auxiliar, e uma unidade combinadora (107) para combinar o primeiro sinal auxiliar com o parâmetro de ganho de compressão para ser obtido um segundo sinal auxiliar e para combinar o sinal de áudio de entrada com o segundo sinal auxiliar para ser obtido o sinal de áudio comprimido.
