Designing Software Synthesizer Plug-Ins in C++

Chapter 13Delay Effects

A deep discussion of audio effect signal processing is beyond the scope of this book; you can find many algorithms and theoretical discussions in Designing Audio Effects Plug-Ins in C++. Audio effects, however, are now standard in most synthesizers. The more popular synth effects (FX) are delay, reverb, chorus/flanger, and vocoder. If you have played a professionally programmed patch on just about any commercial synth, you have most likely heard at least one audio effect operating on the synthesized signal. There is something that audio effects bring out in the patches that can’t be done with oscillators, EGs and filters. Rather than try to give a brief rundown on several effects, let’s focus on the most versatile and ...
