Abstract

aparelho, método e programa de computador para obter um parâmetro que descreve uma variação de uma característica de sinal de um sinal um aparelho para obter um parâmetro que descreve uma variação de uma característica de um sinal com base nos parâmetros de domínio de transformação real que descrevem o sinal de áudio no domínio de transformação compreende um determinador de parâmetro. o de terminador de parâmetro é configurado para determinar um ou mais parâmetros de modelo de um modelo de variação de domínio de transformação que descreve uma evolução dos parâmetros de domínio de transformação dependendo de um ou mais parâmetros de modelo que representam uma característica de sinal, de maneira que um erro de modelo, que representa um desvio entre uma evolução temporal modelada dos parâmetros de domínio de transformação e uma evolução dos parâmetros de domínio de transformação real, seja trazido abaixo de um valor de limiar predeterminado ou minimizado.
