Lv2 is a simple but extensible successor of ladspa plugins, intended to address the limitations of ladspa which many applications have outgrown.

the following extensions are provided:
* lv2 data access (http://lv2plug.in/ns/ext/data-access) - defines a method
for plugin uis to have (possibly marshalled) access to the extension_data
function on a plugin instance.
* lv2 dynamic manifest (http://lv2plug.in/ns/ext/dyn-manifest) - an
lv2-based specification for dynamic data generation.
* lv2 events (http://lv2plug.in/ns/ext/event) - defines a generic
time-stamped event port type, which can be used to create plugins that
read and write real-time events.
* lv2 instance access (http://lv2plug.in/ns/ext/instance-access) - defines
a method for plugin uis to get a direct handle to an lv2 plugin instance
(lv2_handle), if possible.
* lv2 midi events (http://lv2plug.in/ns/ext/midi) - defines an lv2 event
type for standard raw midi.
* lv2 presets (http://lv2plug.in/ns/ext/presets) - defines presets (e.g.
named sets of control values) for lv2 plugins.
* lv2 uri map (http://lv2plug.in/ns/ext/uri-map) - defines a simple
mechanism for plugins to map uris to integers, usually for performance
reasons.
* lv2 ui (http://lv2plug.in/ns/extensions/ui) - defines an interface that
can be used in lv2 plugins and hosts to create uis for plugins.
* lv2 units extension (http://lv2plug.in/ns/extensions/units) - defines a
number of units for use in audio processing.
this package provides the lv2 extensions from the "good" set, a set of extensions which have been discussed and reviewed by the lv2 community and implemented in released software.
