LV2 (LADSPA Version 2) is a set of royalty-free open standards[2] for music production plug-ins and matching host applications. It includes support for the synthesis and processing of digital audio and CV,[3] events such as MIDI and OSC, and provides a free alternative to audio plug-in standards such as Virtual Studio Technology (VST) and Audio Units (AU).

LV2 succeeds the more limited Linux Audio Developer's Simple Plugin API (LADSPA) standard and replaces the Disposable Soft Synth Interface (DSSI) plugin infrastructure ("LADSPA for instruments"), adding abilities such as MIDI capability, custom UIs, and a system allowing extensibility of the initial standard.[4][5]
