Are you interested in creating your own audio plug-ins? Have you had an idea to develop your own custom design? Wondering where to start to create a VST/AU/AAX plug-in?


JUCE is a free development toolkit for creating your own plug-ins, compatible with all the major formats and DAWs. It is possible to write one piece of code and create VST, AU, and AAX formats. If you are new to developing plug-ins, JUCE is a good place to start.


Do you want some help getting started with JUCE? Great! I’ve put together a tutorial with over 3 and a half hours worth of video content to walk you step-by-step through creating a plug-in from start to finish. This is the easiest to learn how to develop software audio effects.



The programming language used in JUCE is C++. If you have never programmed in C++ before, don’t worry. Everything is explained in detail during the video series to make it possible to understand.


If you are brand new to programming, that’s great. As you follow along with the JUCE tutorial, check out many of the resources available on the Hack Audio blog to help with the basics.


Topics of the tutorial are broken up into chapters (shown below). Follow along with the videos to create a channel fader plug-in with a gain slider and polarity button.


For a limited time, take advantage of an introductory offer and get the tutorial for half-price.
