## Comentários

O filtro de variável de estado, por sua natureza, pode criar ressonâncias que fazem os valores intermediários excederem 1,0 (ou -1,0). Para atenuar os problemas criados pela saturação de valores intermediários, o bloco FLTVOL tem uma quantidade programável de dimensionamento de headroom, que é aplicada ao sinal de entrada e depois compensada na saída.

Para obter mais informações, consulte a seção [Bloco de filtro/volume (FLTVOL)](https://docs.xbox.com/pt-BR/build/console-features/audio/overviews/shape-overview.md#ID4EBH) de [Visão geral do SHAPE](https://docs.xbox.com/pt-BR/build/console-features/audio/overviews/shape-overview.md).
