This extension defines an interface that can be used in LV2 plugins and -hosts to create UIs for plugins. The UIs are similar to plugins and reside in -shared object files in an LV2 bundle. UIs are associated with a plugin in RDF -using the triples:

- -
-@prefix ui: <http://lv2plug.in/ns/extensions/ui#> .
-
-<http://my.plugin>   ui:ui     <http://my.pluginui> .
-<http://my.pluginui> a         ui:GtkUI ;
-                     ui:binary <myui.so> .
-
- -

where <http://my.plugin> is the URI of the plugin, -<http://my.pluginui> is the URI of the plugin UI and <myui.so> is -the relative URI to the shared object file.

- -

While it is possible to have the plugin UI and the plugin in the same shared -object file it is probably a good idea to keep them separate so that hosts that -don't want UIs don't have to load the UI code. A UI MUST specify its class in -the RDF data (ui:GtkUI in the above example). The class defines what type the -UI is, e.g. what graphics toolkit it uses. Any type of UI class can be defined -separately from this extension.

- -

It is possible to have multiple UIs for the same plugin, or to have the UI -for a plugin in a different bundle from the actual plugin - this way people -other than the plugin author can write plugin UIs independently without editing -the original plugin bundle.

- -

Note that the process that loads the shared object file containing the UI -code and the process that loads the shared object file containing the actual -plugin implementation are not necessarily the same process (and not even -necessarily on the same machine). This means that plugin and UI code can -not use singletons and global variables and expect them to -refer to the same objects in the UI and the actual plugin. The function -callback interface defined in this header is the only method of communication -between UIs and plugin instances (extensions may define more, though this is -discouraged unless absolutely necessary since the significant benefits of -network transparency and serialisability are lost).

- -

Since the LV2 specification itself allows for extensions that may add new -functionality that could be useful to control with a UI, this extension allows -for meta-extensions that can extend the interface between the UI and the -host. These extensions mirror the extensions used for plugins - there are -required and optional "features" that you declare in the RDF data for the -UI:

- -
-<http://my.pluginui> lv2:requiredFeature <http://my.feature> .
-<http://my.pluginui> lv2:optionalFeature <http://my.feature> .
-
- -

The rules for a UI with a required or optional feature are identical to -those of lv2:Plugin instances: if a UI declares a feature as required, the host -is NOT allowed to load it unless it supports that feature; and if it does -support a feature, it MUST pass an appropriate LV2_Feature struct to the UI's -instantiate() method. These features may be used to specify how to pass -specific types of data between the UI and the plugin port buffers (see -LV2UI_Write_Function for details).

- -

UIs written to this specification do not need to be threadsafe - the -functions defined below may only be called in the same thread the UI main loop -is running in.

- -

Note that this UI extension is NOT a lv2:Feature. There is no way for a -plugin to know whether the host that loads it supports UIs or not, and the -plugin must always work without the UI (although it may be rather useless -unless it has been configured using the UI in a previous session). From the -plugin perspective, control from a UI is the same as control from anywhere else -(e.g. the host, the user): via ports.

- -

A UI does not have to be a graphical widget, it could just as well be a -server listening for OSC input or an interface to some sort of hardware device, -depending on the RDF class of the UI.

This extension defines a number of units for use in audio processing.

- -

For example, to say that a gain port's value is in decibels (units:db)

-
-@prefix units: <http://lv2plug.in/ns/extensions/units#> .
-@prefix eg:    <http://example.org/> .
-
-eg:plugin lv2:port [
-    a            lv2:ControlRateInputPort ;

-    lv2:symbol   "gain" ;
-    lv2:name     "gain" ;
-    units:unit   units:db
-] .
-

Using the same form, plugins may also specify one-off units inline, to give -better display hints to hosts:

-
-eg:plugin lv2:port [
-    a            lv2:ControlRateInputPort ;
-    lv2:datatype lv2:Float ;

-        units:render "%f f"
-    ]
-] .
-
- -

It is also possible to define conversions between various units, which makes -it possible for hosts to automatically and generically convert from a given -unit to a desired unit. The units defined in this extension include conversion -definitions where it makes sense to do so.
