Introduction and Fundamentals

In digital audio signal processing and digital audio effects, we are primarily

concerned with systems that take a discrete, uniformly sampled audio signal,

process it, and produce a discrete, uniformly sampled output audio signal.

Therefore, we start by introducing some fundamental properties of sound

that are used over and over again, then how we represent it as a digital sig-

nal, and then we move on to how we describe the systems that act on and

modify such signals. This is not meant to give a detailed overview of digital

signal processing, which would involve discussion of continuous time sig-

nals, innite s ...
