Sampling Theory
Summary
In this topic we will learn about Sampling Theory. First we will understand what are Discrete Samples of a Continuous Signal. Then we'll read about the foundations of Digital Audio. At last, we'll take a look at some of the Sound File Formats available for us to store sound data.
