Designing Audio Effects Plugins in C++ 2nd Ed.

  • Chapter 16 Audio Filter Designs: FIR Filters



  • implements analog filter responses exactly in FIR form



  • please see the book for a discussion on this plugin; I am not advocating this as a method of designing virtual analog filters
  • however, the frequency response will exactly match the analog filter you specify
  • and the resulting filter will also be linear phase – very interesting and bizarre kind of device here
  • note that this is a mono plugin, and the GUI controls are parsed at the top of the buffer proc cycle and NOT smoothed due to the CPU-intensive nature of this algorithm
