Hi, my name is Jan Wilczek and I am an audio programmer and a researcher. Welcome to WolfSound!

WolfSound's mission is to provide high-quality, informative, and entertaining videos, articles, and courses on how to process sound by exploring mathematics, applying algorithms, and creating code in various programming languages. Topics include sound synthesis, digital signal processing, programming languages for audio (C, C++, Python, Rust), and audio effects. I am also sharing tips on how to learn fast and effectively. Make sure to visit https://www.thewolfsound.com/.

WolfSound enables everybody to learn about audio programming!

In this video, we are implementing a wavetable synthesizer in the JUCE C++ framework. We go through all stages of JUCE synth plugin development: how to handle user input, how to handle MIDI messages, how to create and control oscillators, and finally how to assign oscillators to notes. To implement the code in this video, you need JUCE (I am using version 6.0.5), and a text editor (IDE) with a C++ compiler (I am using Visual Studio 2019). The code we create contains part that can be used in any synthesizer plugin.
