	@abstract	Interfaces for components which implement knowledge of audio file formats.
    @discussion
    	Audio file components are not for the use of clients. Rather, they are called by the
    	implementation of the AudioFile API to implement the various semantics of that API.
		Most of these calls match a call in the AudioFile API which calls through to the component.

		A component may be used in two ways, either associated with a file or not. If a component is
		not associated with a file, it may be used to answer questions about the file type in
		general and whether some data is recognized by that file type. A component is associated
		with a file by calling one of the AudioFile Create, Open or Initialize calls. If a component
		is associated with a file, then it can also be asked to perform any of the calls that
		implement the AudioFile API.
