Internal Program Version: lv2  1.18.10

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
