Abstract
1/1 resumo sistemas e métodos para efetuar modulação de ruído e ajuste de ganho um método inclui receber um primeiro valor de um fator de imisção. o primeiro valor corresponde a uma primeira parte de um sinal de áudio recebido em um codificador de vídeo. o método inclui receber um segundo valor do fator de imisção. o segundo valor corresponde a uma segunda parte do sinal de áudio. o método inclui também gerar um terceiro valor do fator de imisção com base, pelo menos parcialmente, no primeiro valor e no segundo valor e misturar um sinal de excitação com o ruído modulado com base no terceiro valor. outro método inclui determinar um primeiro conjunto de valores de frequência espectral que corresponde a um sinal de áudio e determinar um segundo conjunto de valores de frequência espectral que se aproxima do primeiro conjunto de valores de frequência espectral. um valor de ganho que corresponde a pelo menos uma parte do sinal de áudio é ajustado com base na diferença entre o primeiro conjunto e o segundo conjunto.
