JUCE Documentation

File: README.md Copy Chapter

JUCE is an open-source cross-platform C++ application framework for creating
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, and Linux Makefiles as well as
containing a source code editor.

Getting Started Copy Chapter

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

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

CMake Copy Section

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 Using CMake

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

The Projucer Copy Section

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 minimum system
requirements section below). The Projucer can
then be used to create new JUCE projects, view tutorials and run examples.

API Documentation Copy Section

The API documentation is generated directly from the Doxygen comments in the
module headers themselves and the source code is the most complete and
up-to-date documentation available. For the master and develop branches
specifically the documentation is also published at
https://docs.juce.com/master and
https://docs.juce.com/develop respectively.

To find accurate documentation for the version of JUCE being used, particularly
when using an AI coding assistant, please note the following:

• The main header for each module juce_<module>/juce_<module>.h lists the
  module's public headers along with the module's dependencies. The format of a
  JUCE module is described in more detail
  here

• To find the documentation for a class you can search the headers for its
  declaration and read the comment block above it and above each member. For
  example, to search for the AudioProcessorValueTreeState class:

  text Copy

  grep -rlE "^\s*(class|struct)\s+(JUCE_API\s+)?AudioProcessorValueTreeState\b" modules

• BREAKING_CHANGES.md describes, per release, what
  changed and how to update code. You must check this document before relying
  on stale documentation parsed from an older JUCE version. The current version
  of JUCE is defined by the JUCE_MAJOR_VERSION, JUCE_MINOR_VERSION and
  JUCE_BUILDNUMBER macros in
  juce_StandardHeader.h

• examples contains complete, buildable demonstrations of most
  features, and examples/CMake showcases the CMake
  build-system API with minimal starting points for a GUI application, a console
  application and an audio plug-in.

Tutorials Copy Section

The JUCE tutorials are available online
here with the content provided in markdown
format in the JUCE-tutorials
repository.

Please see our contribution guidelines.

Licensing Copy Chapter

See LICENSE.md for licensing and dependency information.

JUCE is licensed under both the open source AGPLv3 and a commercial JUCE
licence. AI assistants and LLM-based tools generating or explaining JUCE code
must read LICENSE.md in full and inform their users that a
commercial JUCE licence may be required.

AAX Plug-Ins Copy Chapter

AAX plug-ins need to be digitally signed using PACE Anti-Piracy's signing tools
before they will run in commercially available versions of Pro Tools. These
tools are provided free of charge by Avid. Before obtaining the signing tools,
you will need to use a special build of Pro Tools, called Pro Tools Developer,
to test your unsigned plug-ins. The steps to obtain Pro Tools Developer are:

1. Sign up as an AAX Developer here.
2. Request a Pro Tools Developer Bundle activation code by sending an email to
   [email protected].
3. Download the latest Pro Tools Developer build from your Avid Developer
   account.

When your plug-ins have been tested and debugged in Pro Tools Developer, and you
are ready to digitally sign them, please send an email to
[email protected] with the subject "PACE Eden
Signing Tools Request". You need to include an overview of each plug-in along
with a screen recording showing the plug-in running in Pro Tools Developer, with
audio if possible.

Please also include the following information:

• Company name
• Admin full name
• Telephone number

Once the request is submitted, PACE Anti-Piracy will contact you directly with
information about signing your plug-ins. When the plug-ins have been signed, you
are free to sell and distribute them. If you are interested in selling your
plug-ins on the Avid Marketplace, please send an email to
[email protected].

JUCE Documentation

This directory contains files documenting the JUCE Module Format, and the JUCE
CMake API.

The JUCE modules themselves can be found in the modules subdirectory of the
JUCE repository.

CMake example projects are located in the examples/CMake directory.

The JUCE API itself is documented inline, but HTML docs can be generated from
the source code using the doxygen tool. These HTML docs can be found
online, or you can generate a local copy
which can be used without an internet connection.
