JUCE is an open-source cross-platform C++ application framework for creating high quality desktop and mobile applications, including VST, VST3, AU, AUv3, AAX and LV2 audio plug-ins and plug-in hosts. JUCE can be easily integrated with existing projects via CMake, or can be used as a project generation tool via the Projucer, which supports exporting projects for Xcode (macOS and iOS), Visual Studio, Android Studio, Code::Blocks and Linux Makefiles as well as containing a source code editor.

Getting Started

The JUCE repository contains a master and develop branch. The develop branch contains the latest bugfixes and features and is periodically merged into the master branch in stable tagged releases (the latest release containing pre-built binaries can be also downloaded from the JUCE website).

JUCE projects can be managed with either the Projucer (JUCE's own project-configuration tool) or with CMake.

The Projucer

The repository doesn't contain a pre-built Projucer so you will need to build it for your platform - Xcode, Visual Studio and Linux Makefile projects are located in extras/Projucer/Builds (the minimum system requirements are listed in the System Requirements section below). The Projucer can then be used to create new JUCE projects, view tutorials and run examples. It is also possible to include the JUCE modules source code in an existing project directly, or build them into a static or dynamic library which can be linked into a project.

For further help getting started, please refer to the JUCE documentation and tutorials.

CMake

Version 3.22 or higher is required. To use CMake, you will need to install it, either from your system package manager or from the official download page. For comprehensive documentation on JUCE's CMake API, see the JUCE CMake documentation. For examples which may be useful as starting points for new CMake projects, see the CMake examples directory.

Building Examples

To use CMake to build the examples and extras bundled with JUCE, simply clone JUCE and then run the following commands, replacing “DemoRunner” with the name of the target you wish to build.

cd /path/to/JUCE
cmake . -B cmake-build -DJUCE_BUILD_EXAMPLES=ON -DJUCE_BUILD_EXTRAS=ON
cmake --build cmake-build --target DemoRunner
