FilterDeMystifier is an educational filter plug-in designed to demonstrate how poles and zeros influence the sound of equalizers and vocal filters. It provides an insightful visual approach to understanding filter behavior, making it an excellent tool for those interested in the fundamentals of digital audio processing. Users can explore the effects of filter parameters through a clear and straightforward interface.

The plug-in features dynamic visualizations, including a rotatable 3D plot that displays the transfer function and the magnitude response on the z-plane. This interactive representation helps users grasp complex filter concepts by observing real-time changes. Several presets are included to showcase the range of sounds achievable, all accessible through an intuitive graphical user interface.

Originally developed as part of a final exam project for a Digital Audio Effects course, FilterDeMystifier offers an educational experience grounded in practical application. Users should exercise caution as disabling safety features may produce harsh or unpleasant sounds. For those interested in exploring the underlying technology further, the source code is openly available, encouraging deeper learning and experimentation.
