Sound Component-Defined Routines

This section describes the routines you need to define in order to write a sound component. You need to write routines to

• load, configure, and unload your sound component
• add and remove audio sources
• read and set component settings
• control and process audio data

Some of these routines are optional for some types of sound components. All routines return result codes. If they succeed, they should return noErr. To simplify dispatching, the Component Manager requires these routines to return a value of type ComponentResult.

See "Writing a Sound Component" beginning on page 5-8 for a description of how you call these routines from within a sound component. See "Sound Manager Utilities" beginning on page 5-33 for a description of some Sound Manager utility routines you can use in a sound component.
