Constantes IPropertyBag de codec et DSP
Il existe deux méthodes de définition des propriétés sur les objets codec et DSP par programmation, à l’aide de l’interface IPropertyBag ou de l’interface IPropertyStore . Les propriétés les plus courantes sont disponibles via les deux interfaces. L’utilisation de l’interface IPropertyStore est préférable à IPropertyBag.
