JUCE

JUCE is an open-source, cross-platform application framework written in C++ designed for developing desktop and mobile applications, including VST, VST3, AU, AUv3, AAX, and LV2 audio plug-ins and plug-in hosts. JUCE can be easily integrated into existing projects using CMake, or it can be used as a project generation tool via Projucer, which supports project export for Xcode (macOS and iOS), Visual Studio, Android Studio, and Linux Makefiles, and also includes a source code editor.

The JUCE framework is the most widely used framework for developing audio applications and plug-ins, and is utilized by all major companies in the audio industry, either to support their own software research and development or as part of their publicly available products.

JUCE allows developers to focus on the most important parts of their software by handling the differences between operating systems (both desktop and mobile) and plug-in formats. With a project based on the JUCE framework, you can write your software once, and it will work the same no matter where you deploy it.
