LV2, an acronym for Linux Audio Developer's Simple Plugin API (LADSPA) version 2, is an open standard for audio plug-ins and matching host applications. It includes support for audio synthesis (generation) and digital signal processing of digital audio and MIDI. It provides an open alternative to other standards such as Virtual Studio Technology (VST) and Audio Units.

Currently there is support for LV2 in Ardour, Calf Studio Gear,[1] Qtractor, Traverso DAW,[2] Harrison Mixbus,[3] MusE and the 2.0.6 and above versions of Audacity.[4] It is also the plugin format used by the Mod Duo[5] hardware effects unit. KXStudio's Carla is a multiplatform host supporting many plug-in formats including LV2.

LV2 replaces the former Disposable Soft Synth Interface (DSSI) plugin infrastructure, and succeeds the more limited LADSPA standard, adding MIDI capability, custom UIs, a system allowing extensibility of the initial standard, and other features.[6]

A wide range of plugins are available in LV2 format, a full list is available from the site.
