LV2 is a portable plugin standard for audio systems, similar in scope to LADSPA,
|
|
VST, AU, and others. It defines a C API for code and a format for data files
|
|
which collectively describe a plugin. LV2 consists of a simple core (roughly
|
|
equivalent in power to LADSPA) which can be extended to support more advanced
|
|
functionality. This allows the interface to be "grown" to accommodate the needs
|
|
of real software as they arise.
|
|
|
|
LV2 is both a stable interface and a forward-moving project: there is a stable
|
|
set of "official" extensions in use while new functionality is actively
|
|
developed. Anyone can extend LV2, which allows developers to try out new ideas
|
|
and ensure they work in practice. Good extensions are vetted by the community
|
|
and included in the official distribution so they can be relied on to be widely
|
|
supported. This open development model means developers can always scratch their
|
|
itch without a central authority getting in the way. The current stable release
|
|
includes most functionality required by modern plugins, including:
|
|
|
|
* Audio, control, "control voltage" (audio-rate control), and event
|
|
(e.g. MIDI) input and output
|
|
* Expressive open-ended port metadata, including:
|
|
- "Meaningful" controls (e.g. gain or envelope attack) allowing intelligent
|
|
host control or UI generation
|
|
- Control units (e.g. Hz, octaves, dB)
|
|
- Multi-channel port groups (e.g. stereo, 5.1 surround, ambisonics
|
|
* Embeddable GUIs in any toolkit, with support for a full plugin/UI split
|
|
(including network transparency in capable hosts)
|
|
* Ability to bundle any files (e.g. samples or impulses) with plugins
|
|
* Presets (bundled and/or user saved)
|
|
* Plugin state saving and restoring
|
|
* Host-managed logging
|
|
* Non-realtime plugin worker methods (simple and portable host-managed
|
|
threading)
|
|
* Message-based plugin communication, allowing plugins/UIs to have advanced
|
|
interfaces without host support or specifications getting in the way
|
|
* Transport awareness, both real time and tempo time (bars, beats, etc-.)
|
|
|
|
LV2 has graceful compatibility "baked in": for example, a simple amplifier
|
|
plugin might have audio in/out with a gain control, and function in any host.
|
|
The same plugin could have a fancy GUI and transport awareness which optionally
|
|
work in hosts that support these features. Conversely, hosts know not to load
|
|
plugins that require features it does not support.
|
|
|
|
See the specification index for complete documentation. If you are a host or
|
|
plugin author and need missing functionality, please file a ticket or let us
|
|
know your requirements on the mailing list. LV2 is a community project that
|
|
depends on your feedback to improve - unknown requirements are unmet
|
|
requirements!
