-""" . - - - a owl:Ontology ; - owl:imports ; - lv2:documentation """ -

LV2 is an interface for writing audio processors, or plugins, in -C/C++ which can be dynamically loaded into many applications, or hosts. -This core specification is simple and minimal, but is designed so that -extensions can be defined to add more advanced features, making it -possibly to implement nearly any feature imaginable.

- -

LV2 maintains a strong distinction between code and data. -Plugin code is in a shared library, while data is in a companion data file -written in Turtle. -Code, data, and any other resources (e.g. waveforms) are shipped together in a -bundle directory. The code contains only the executable portions of the -plugin which inherently must be written in code. All other data is -provided in the data file(s). This makes plugin data flexible and extensible, -and allows the host to do everything but run the plugin without loading or -executing any code. Among other advantages, this makes hosts more robust -(broken plugins can't crash a host during discovery) and allows generic tools -and non-C programs to work with LV2 data. LV2 itself and extensions are -distributed in a similar way.

- -

An LV2 plugin library is suitable for dynamic loading (e.g. via -dlopen()) and provides one or more plugin descriptors via the -lv2_descriptor() function. These can be instantiated to create -plugin instances, which can be run directly on data or connected -together to perform advanced signal processing tasks.

- -

Plugins communicate via ports, which can transmit any type of data. -Data is processed by first connecting each port to a buffer, then -repeatedly calling a plugin's run() method to process blocks of -data.

- -

This core specification defines two types of port, equivalent to those in LADSPA: lv2:ControlPort and lv2:AudioPort. -Audio ports contain arrays with one float element per sample, -allowing a block of audio to be processed in a single call to -run(). Control ports contain single float values, -which are fixed and valid for the duration of the call to run(). -Thus the control rate is determined by the block size, which is -controlled by the host (and not necessarily constant).

- -

Threading Rules

- -

To faciliate use in multi-threaded programs, LV2 functions are partitioned -into several threading classes:

- - - - - - - - - - - - - -
Discovery ClassInstantiation ClassAudio Class
lv2_descriptor()LV2_Descriptor::instantiate()LV2_Descriptor::run()
LV2_Descriptor::extension_data()LV2_Descriptor::cleanup()LV2_Descriptor::connect_port()
LV2_Descriptor::activate()
LV2_Descriptor::deactivate()
- -

The rules that hosts MUST follow are:

-
    -
  • When any function is running for a plugin instance, -no other function in the same class may run for that instance.
    • -
  • When a Discovery function is running, -no other functions in the same shared object file may run.
    • -
  • When an Instantiation function is running for a plugin instance, -no other functions for that instance may run.
    • -
- -

Any simultaneous calls that are not explicitly forbidden by these rules are -allowed. For example, a host may call run() for two different -plugin instances simultaneously.

- -

Plugin functions in any class MUST NOT manipulate any state which might -affect other plugin or host code, e.g. by using non-reentrant global -functions.

- -

Extensions to this specification which add new functions MUST declare in -which of these classes the functions belong, define new classes for them, or -otherwise precisely describe their threading rules.

The minor version of an LV2 Resource. This property is used (along with -lv2:microVersion) by hosts to distinguish different versions of a compatible -resource, e.g. to load only the bundle with the most recent version.

- -

The version of an LV2 resource is composed of two fields: minor version, -and micro version. These have the usual semantics:

- -
    -
  • The minor version MUST be incremented when backwards (but not -forwards) compatible additions are made, e.g. the addition of a port to a -plugin.
    • - -
  • The micro version is incremented for changes which do not affect -compatibility at all, e.g. bug fixes or documentation updates.
    • -
- -

Note there is deliberately no concept of a major version: all versions of an -LV2 resource with a given URI are by definition backwards compatible. More -precisely: replacing a resource with a newer version of that resource MUST NOT -break anything. If a change is made which breaks this rule, the URI -of the resource MUST be changed. In contexts where a full (e.g. SemVer conformant) version number is required, the -major version of all released LV2 resources is 1.

- -

Plugins and extensions MUST adhere to the following rules:

-
    -
  • All versions of a plugin with a given URI MUST have the same set of -mandatory (i.e. not lv2:connectionOptional) ports with respect to lv2:symbol -and rdf:type. In other words, every port on a specific version of a plugin has -a lv2:symbol and a set of rdf:types; all future versions of that plugin are -guaranteed to have a port with the same lv2:symbol and at least those -rdf:types. New types may be added only if doing so does not break -compatibility, i.e. if old hosts will continue to work correctly with the new -plugin.
    • - -
  • New ports MAY be added without changing the plugin URI if and only if they -are lv2:connectionOptional and the minor version is incremented.
    • - -
  • The minor version MUST be incremented if the index of any port (identified -by its symbol) is changed.
    • - -
  • All versions of an extension MUST be compatible in the sense that an -implementation of the new version can interoperate with an implementation of -any previous version.
    • -
- -

(Note these rules are not necessarily exhaustive)

- -

Anything that depends on a specific version of a plugin (e.g. a -serialisation that references ports by index) MUST refer to the plugin by both -URI and version. However, implementations should be tolerant and extensions -should be designed such that there is no need to do this (e.g. indices should -only be meaningful for a particular plugin instance at run-time).

- -

When hosts discover several installed versions of a resource, they SHOULD -warn the user and load only the most recent version.

- -

An odd minor or micro version indicates that the resource is a -possibly unstable development version. Hosts and tools SHOULD clearly indicate -this wherever appropriate. Several versions of a resource with an odd version -may exist; i.e. it is acceptable to work on a development version of a resource -(e.g. in source control) without worrying about version numbers as long as -either the minor or micro version is odd.

- -

This property describes half of a resource version. See also lv2:minorVersion, the -property which describes the other half.

-""" . - -lv2:microVersion a rdf:Property , owl:DatatypeProperty ; - rdfs:domain lv2:Resource ; - rdfs:range xsd:nonNegativeInteger ; - rdfs:label "micro version" ; - lv2:documentation """ -

The micro component of a Resource's version.

- -

Releases of plugins and extensions MUST be explicitly versioned. Correct -version numbers MUST always be maintained for any versioned resource that is -published. For example, after a release, if a change is made in the development -version in source control, the micro version MUST be incremented (to an odd -number) to distinguish this modified version from the previous release.

- -

- -

This is a required property of a Plugin which MUST be included in the -bundle's manifest.ttl file. The lv2:binary of an lv2:Plugin is the -shared object containing the lv2_descriptor() function which can -be used to access the descriptor for that plugin. This property may be used -similarly by extensions to relate other resources to their implementations.

-""" . - -lv2:appliesTo a rdf:Property , owl:ObjectProperty ; - rdfs:domain lv2:Resource ; - rdfs:range lv2:Plugin ; - rdfs:label "Applies to" ; - lv2:documentation """ -

Specifies that a resource is related to a plugin. This is primarily intended -for discovery purposes: bundles that describe resources that work with -particular plugins (e.g. presets or user interfaces) SHOULD use this predicate -in manifest.ttl to relate the resource to the applicable -plugin(s), e.g.:

-
-<thing>
-    a             ext:Thing ;
-    lv2:appliesTo <plugin> ;
-    rdfs:seeAlso  <thing.ttl> .
