lv2

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.
