FX-Objects

The FX-Objects module contains specialized audio DSP C++ objects that are inlcuded with and documented in Will Pirkle's new plugin programming book. These objects will be available in May 2019 when the 2nd Edition of Designing Audio Effects Plugins in C++ is published and will be free to use in your projects, commercial or personal. More...
