Detailed Description

The AnalogFIRFilter object implements a somewhat silly algorithm that implaments an analog magnitude response as a FIR filter. NOT DESIGNED to replace virtual analog; rather it is intended to show the frequency sampling method in an easy (and fun) way.

Audio I/O:

• Processes mono input to mono output.

Control I/F:

• Use AnalogFIRFilterParameters structure to get/set object params.
