As I was learning C++, I had been building a collection of audio development tools that I bring to new projects. It occurred to me that if this collection was useful to me, it may also be useful to others. I formalized my tool into an openFrameworks addon, 'openFrameworks Audio Tool Kit', or ofxATK. This project is no longer maintained as my attention moved fully to Pedal.
