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" for a description of how you call these routines from within a sound component. See "Sound Manager Utilities" for a description of some Sound Manager utility routines you can use in a sound component.
