These parameters can then be bound to specific GUI controls. We can create parameters that will be stored in the value tree state. We can think of it as a container suitable for all our plugin’s parameters. Audio Processor Value Tree StateĪ very important class, that we will use in this tutorial, is the AudioProcessorValueTreeState. The plugin editor of our plugin will contain the graphical controls and the bindings to the plugin’s parameters. The plugin processor of our plugin will contain the filtering code. The plugin editor is the main GUI class that allows the developer to create sliders, checkboxes, buttons, etc., and connect them to the plugin parameters. The plugin processor handles everything related to signal processing within the plugin and does not handle graphical user interface (GUI). If you already know JUCE, you can skip this paragraph.Įvery JUCE plugin has two main components: Setting the parameters of the implemented plugin in Projucer.įor example, I decided to generate only the VST3 plugin format (marked 2 in Figure 4) and use the C++ 20 standard.Īfter you completed the setup, click on Save and Open in IDE (marked 3 in Figure 4). If so, click on the Project Settings (marked 1 in Figure 4) icon next to the project name.įigure 4. You then will have to choose the folder which will contain your project folder (mine is called JUCEprojects, since I put there most of my JUCE projects).Īt this point, you could already generate your project but you may want to provide some additional metadata. You should see a window similar to the one in Figure 3.Ĭhoose Plugin->Basic type, write your Project Name, select the target IDE (mine is Visual Studio 2019), and click Create Project.

So let’s start building our plugin! Plugin Project Setup in ProjucerĪfter you install JUCE, launch the Projucer app and select File -> New Project.

This tutorial does not assume that you worked in JUCE before.Īnd if you haven’t, you will learn plenty of useful stuff that you can readily apply in the professional audio programming market 🙂

Therefore, we can write the plugin code once and build plugins for various digital audio workstations (e.g., Reaper, Ableton, ProTools, etc.). It is very handy in audio plugin creation because it provides wrappers around specific APIs like VST3 or AAX. The JUCE framework is a C++ framework for building audio plugins and applications. The DSP structure that we are going to implement. This article is purely a plugin implementation of the previously presented algorithm.įigure 2 shows the audio processing algorithm that we are implementing in JUCE.įigure 2. If you want, to understand how this structure works and why it is filtering, I invite you to read that article first. The structure, that we are going to implement, is the allpass-based parametric lowpass/highpass filter from the previous article. You will complete building this plugin at the end of this tutorial. In this article, I will guide you step-by-step through the process of implementing a lowpass/highpass filter audio plugin with the JUCE C++ framework.įigure 1. Let’s build a lowpass/highpass filter audio plugin from scratch! Introduction
