FilterDemo

This project will build a simple Audio Unit effect and a Cocoa UI to go along with it. The effect is a simple resonant low-pass filter which has two parameters: cutoff frequency and resonance. It demonstrates how to implement a custom property for communicating information between the Audio Unit and its view. Also, it shows how to publish factory presets. The Cocoa view features a resizeable real-time display of the frequency-response curve which can be directly manipulated through a control point.
