This project is considered end-of-life due to its plugin UI's relying on the already phased-out GTK2 framework. It will be kept alive for other projects that depend on its code or the plugins, but no further development other than maintenance will happen here. Please refer to the new VST3 project calfNXT if you're looking for a successor of the plugins.
Calf Studio Gear is an audio plug-in pack for LV2 and JACK environments under LINUX operating systems. The suite contains lots of effects (delay, modulation, signal processing, filters, equalizers, dynamics, distortion and mastering effects), instruments (SF2 player, organ simulator and a monophonic synthesizer) and tools (analyzer, mono/stereo tools, crossovers). Calf Studio Gear aims for a professional audience.

Once installed there are a couple of manuals available.
- "man calf" displays some general instructions
- "man calfjackhost" gives some hints on how to use the calf rack application
- /usr/[local]/share/doc/calf (depending on your installation path) contains a HTML manual on how to use the plug-ins user interface
- The plug-in manuals can also be accessed via the GUI menus.
In all cases, looking at .github/workflows/build.yml can give you a quick hint how it can be done on the systems which we test.
