Not just another theory-heavy digital signal processing book, nor another dull build-a-generic-database programming book, Designing Audio Effect Plug-Ins in C++ gives you everything you everything you need to know to do just that, including fully worked, downloadable code for dozens of professional audio effect plug-ins and practically presented algorithms. With this book, you get access to a companion website where you can download the accompanying Rapid Plug-In Development software to compile and test the book examples, all the code examples, and view student plug-ins and tutorial videos on the development software. Start with an intuitive and practical introduction to the digital signal processing (DSP) theory behind audio plug-ins, and quickly move on to plug-in implementation, gain knowledge of algorithms on filtering, delay, reverb, modulated effects, dynamics processing, and more. You will then be ready to design and implement your own unique plug-ins on any platform and within most any host program.

Readers are expected to have some knowledge of C++, and high school math.


This is one of the most important and exciting audio books I’ve seen in a long, long time. It tackles the hottest topic in the industry today—authoring plug-ins. Audio design has transitioned from a hardware world to a software one, and this book places you at the forefront of the revolution. It gives you all the tools you’ll need, from signal-processing theory to completed code, to fully understand and write C++ audio plug-ins. When you finish this book, you’ll be playing music through your own real-time plug-ins, and you will have acquired perhaps the most valuable skill set sought by today’s audio engineers. —Ken C. Pohlmann, Professor Emeritus, University of Miami

Finally, the keys to the digital kingdom are made available to all recording engineers. Learn how plug-ins work, gaining a deep understanding of their rich capabilities, tempered by an informed intuition about their sonic limitations. You’ll be a better user, and—should you be so inclined—you’ll build a better processor. That’s right. Designing Audio Effect Plug-Ins in C++ gives you the theory, the skills, the software tools, and the hands-on examples you need to build your own delays, reverbs, compressors, and more. Perfect audio effects—if you can’t buy ‘em, build ‘em. —Alex U. Case, author, Sound FX and Mix Smart (Focal Press)

This is a very practical introduction to digital audio signal processing that makes writing DSP plugins in C++ easy. The author brings a career of knowledge and experience to one easily understood and very un-stuffy book that takes the mystery out of a complex set of topics. Highly recommended. —Joe Bryan, audio guru and inventor of UAD-1 powered plug-ins
