About the Standard Sound Dialog Component

The standard sound dialog component allows your application to present the user with a dialog box to configure sound settings and to get the settings that the user provides. The standard sound dialog component API is based on the standard image-compression dialog component API, which offers similar programmatic controls for image compression settings. An example of the dialog box provided by the standard sound dialog component is shown in Figure 1.

Figure 1 Standard Sound Dialog

The standard sound dialog component implements calls that are appropriate for sound processing. Because the standard sound dialog component is based on the standard compression component, many calls were originally developed for image-related settings. The names of some calls may therefore seem counterintuitive when used in the context of sound compression.

The standard sound dialog component is currently used for the configuration dialog boxes in the sound and music movie exporter components.
