None Audio Application Framework

September 2, 2021 ยท View on GitHub

About

To provide a framework that provides a simple drop-in component system and handles any non-creative work consistently.

This framework is built on the JUCE audio plugin framework, which provides all of the tools for making the actual audio plugin.

While JUCE is a great framework, I found that there are some tasks which are repetitive (such as state maintenance), and plenty things that could go wrong in making a JUCE application. This framework is a solution to a decoupled, organized, and uniform framework that will allow even giant apps to be built, while maintaining maintainability and simplicity.

Current version - 0.0.0

This is super alpha and definitely not considered production yet, although it is already useful.

Documentation

The framework contains 4 main types of entities.

  • GUI Components
  • Midi/Audio Processors
  • States
  • State Modifiers

With these four entities, any app should be constructable. The framework aims to handle everything that is not specifically creating a GUI, running audio processes, referring to states, and modifying states.

The NoneApp folder contains a JUCE project that is built using this framework. It is a simple FM modulator, and uses every component of the framework. It generates a sine using a state that contains the frequency information. A state modifier modulates the generator's state, by way of a GUI rotary slider component. This results in a synthesizer with a controllable frequency modulator.

The juce_modules folder contains the modules that this framework used in development.

Step by step

  1. To create a new app, just copy and rename the NoneApp. You'll need Projucer from JUCE to open the project file.
  2. You'll need to copy the folder modules/none_app. That's the starting project. You will edit this module to configure the app. Consider renaming the namespace to your desire.
  3. Include your module in the JUCE project, by adding a module in Projucer.
  4. If you renamed your namespace, you'll need to change the app's variable declaration in PluginProcessor.h.

Known bugs

  • Automation is non-functional in Fl Studio. The parameter only updates on play.

License

This framework contains two different licenses. This repository contains JUCE module code for convenience and as a way of preserving the framework's integrity. A licence document is included in the juce_modules folder which details the JUCE license.

Aside from JUCE, this library is licensed with the MIT license, making it very free.
