16.1 Introduction: Algorithmic Reverb Effects

This chapter introduces several different algorithms for creating artificial, digital reverberation (reverb). These effects create many delayed repetitions of an input signal to simulate reflections in an acoustic space. The possible algorithms for creating artificial reverb are only limited by an engineer’s creativity. This chapter presents three algorithms that can serve as foundational approaches: Schroeder, Moorer, and Jot feedback delay network (FDN).

Rather than creating artificial reverberation by using convolution with a measured impulse response (Section 11.8.3), algorithmic reverb is based more on the concept of creating successively ...
