+
+This is a vocabulary for units typically used for control values in audio
+processing.
+
+For example, to say that a gain control is in decibels:
+
+ :::turtle
+ @prefix units: &lt;http://lv2plug.in/ns/extensions/units#&gt; .
+ @prefix eg: &lt;http://example.org/&gt; .
+
+ eg:plugin lv2:port [
+ a lv2:ControlPort , lv2:InputPort ;
+ lv2:index 0 ;
+ 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:
+
+ :::turtle
+ eg:plugin lv2:port [
+ a lv2:ControlPort , lv2:InputPort ;
+ lv2:index 0 ;
+ lv2:symbol "frob" ;
+ lv2:name "frob level" ;
+ units:unit [
+ a units:Unit ;
+ rdfs:label "frobnication" ;
+ units:symbol "fr" ;
+ units:render "%f f"
+ ]
+ ] .
+
+It is also possible to define conversions between various units, which makes it
+possible for hosts to automatically convert between units where possible. The
+units defined in this extension include conversion definitions where it makes
+sense to do so.
