Calf Studio Gear, often referred to as Calf Plugins, is a set of open source LV2 plugins for the Linux platform. The suite intends to be a complete set of plugins for audio mixing, virtual instruments and mastering. As of version 0.90.0 there are 47 plugins in the suite.
History
Calf Studio Gear development started in late 2007 when the LV2 plugin standard was in its infancy. Calf Studio Gear was one of the first projects to bring graphical audio plugins to Linux. The first versions up to 0.0.19 included support for LADSPA and DSSI as well which was dropped in December 2011.
The project was initiated by Krzysztof Foltman. In 2009 Markus Schmidt became interested in development of the plugin suite due to his frustration with proprietary software. He has been a driving force behind the plugins ever since and has been responsible for the overall design of Calf Studio Gear, as well as being the brains behind the DSP of many of its plugins.
