Abstract
1/1 resumo sistemas e métodos para realização de controle de ganho um método particular inclui determinação, com base em um espaçamento inter-par de linha espectral (lsp) correspondendo a um sinal de áudio, que o sinal de áudio inclui um componente correspondendo a uma condição de geração de artefato. o método inclui também, em resposta à determinação que o sinal de áudio inclui o componente, ajuste de um parâmetro de ganho correspondendo ao sinal de áudio. por exemplo, o parâmetro de ganho pode ser ajustado através de atenuação de ganho e/ou regularização de ganho.
