## Detailed Description

A Wrapper for the audiotestsrc plugin.

Please note that, though using the underlying GObject is fine, using its C type is not guaranteed to be API stable across releases because it is not guaranteed to always remain the same. Also, not all plug-ins are available on all systems so care must be taken that they exist before they are used, otherwise there will be errors and possibly a crash.
