Designing Audio Effect Plug-ins in C++ (book review)

I’ve been writing a series of posts here over the last few months discussing the JUCE C++ application framework and how useful it’s been in creating the ‘Scumbler’ looping audio performance application that’s my current nights & weekends project. One of the important requirements that I had for the project was that it be able to use existing VST or AU audio effects plug-ins to process the audio during performance.

Designing Audio Effects Plug-ins in C++

Over the years since I graduated with a degree in electronic and computer music, I’ve accumulated a fairly large shelf of books on digital signal processing theory and applications. Earlier this year, Focal Press released what’s the most usable book on writing audio effects plug-ins. It’s very easy to find books for theorists, or for people who already have very heavy math backgrounds explaining the concepts behind DSP; it’s rarer to find resources targeted at interested and motivated practitioners. Anyone coming to this book with a relatively solid background in C++ programming and high-school math (trig and at least pre-calculus) should be able to work through it and come out the other end with an understanding of much of the DSP that’s needed out in the wild.  (more…)
