Classes
class	Plugin
	Vamp::Plugin is a base class for plugin instance classes that provide feature extraction from audio or related data. More...
class	PluginHostAdapter
	PluginHostAdapter is a wrapper class that a Vamp host can use to make the C-language VampPluginDescriptor object appear as a C++ Vamp::Plugin object. More...
class	PluginLoader
	Vamp::HostExt::PluginLoader is a convenience class for discovering and loading Vamp plugins using the typical plugin-path, library naming, and categorisation conventions described in the Vamp SDK documentation. More...
class	PluginWrapper
	PluginWrapper is a simple base class for adapter plugins. More...
class	PluginInputDomainAdapter
	PluginInputDomainAdapter is a Vamp plugin adapter that converts time-domain input into frequency-domain input for plugins that need it. More...
