Filter Design
Abstract
A filter can emphasize or de-emphasize certain parts of the frequency spectrum of a sound. Visually, it can be shown as a pair of graphs over the frequency domain called the frequency response, consisting of both magnitude response and phase response. Several types of filters are commonly used in audio effects for manipulating the frequency content of the signal. Filters are also the basis for many types of audio effects. In this chapter, we will look at the basics of designing digital filters. We will show how many of the most important digital filters can be derived from the simplest possible designs.
