Reverberation

Reverberation (reverb) is one of the most often used effects in audio production. In this chapter, we will look at the causes, the main characteristics, and the measures of reverb. We then focus on how to simulate reverb. First we describe algorithmic approaches to generating reverb, focusing on two classic designs. Then we look at a popular technique for generating a room impulse response, the image source method. Next, we describe convolutional reverb, which adds reverb to a signal by convolving that signal with a room impulse response, either recorded or simulated (such as from using the image source method). This chapter concludes by looking at implementation details and applications.
