LV2

The LV2 plugin standard is the successor to LADSPA. LV2, which stands for LADSPA version 2, is intended to address the limitations of LADSPA. LV2 plugins can easily be extended and most LV2 plugins come with custom GUI's. Supported hosts include Ardour, Qtractor and Carla. A popular collection of LV2 plugins is the Calf plugin suite.
