"Wrappers to run your CLAP in other plugin formats instantly."

The clap-wrapper Project

The clap-wrapper project allows you to wrap your CLAP plugin into other plugin or standalone executable formats, letting your plugin run in hosts which don't support the CLAP format and allowing you to distribute standalone executable versions of your CLAP.

Our wiki is the root of our developer documentation.

Currently the clap-wrapper supports projecting a CLAP into

• VST3
• Audio Unit v2 (AUv2)
• A Simple Standalone

The clap-wrapper also provides a variety of deployment, linkage and build time options to CLAP developers.

The Core Idea

The core idea of clap-wrapper is as follows

1. The clap-wrapper is an implementation of a clap host which will load your CLAP using a variety of techniques.
2. The clap-wrapper provides an implementation of a plugin format or standalone executable which implements the format to the host or OS, but uses that host to load your clap.

And with that, voila, your CLAP can appear in a VST3 or AUv2 host or can appear to be a self contained standalone executable. Available features in CLAP are transposed to equivalent features in the target format.

Getting Started

Our wiki is the root of our developer documentation. Since building a clap-wrapper involves several choices we strongly suggest you consult it first.

The simplest form of a clap wrapper, though, is a VST3 which dynamically loads a CLAP of the same name using your copy of the VST3 and CLAP SDK. To build this, you can use the simple CMake command

git clone https://github.com/free-audio/clap-wrapper.git
mkdir build
cmake -B build \ 
      -DCLAP_SDK_ROOT={path to clap sdk} \
      -DVST3_SDK_ROOT={path to vst3 sdk} \
      -DCLAP_WRAPPER_OUTPUT_NAME="The Name of your CLAP"

If you'd like to also build for AUv2 include -DCLAP_WRAPPER_BUILD_AUV2=ON and the SDK in the folder AudioUnitSDK.

Licensing

The clap-wrapper project is released under the MIT license. Please note that using the clap-wrapper project to wrap a VST3 requires either (1) you use the VST3 SDK under the GPL3 license, and as such are open source or (2) you agree to the VST3 license to generate the wrapper.
