Using JUCE, the objects in VFLib, and a pinch of external code I have put together a fully functional application demonstrating the basics of thread safety, audio i/o callback best practices, proper linking of GUI controls to the audio rendering pipeline, and exercising some of the JUCE audio processors.
This repository is FULLY SELF CONTAINED, no external dependencies. You don’t even have to download JUCE (or TagLib) - all is included!
