* The LADSPA (Linux Audio Developer's Simple Plugin API) element is a bridge
* for plugins using the <ulink url="http://www.ladspa.org/">LADSPA</ulink> API.
* It scans all installed LADSPA plugins and registers them as gstreamer
* elements. If available it can also parse LRDF files and use the metadata for
* element classification. The functionality you get depends on the LADSPA plugins
* you have installed.
