Computers can be extremely powerful machines, capable of sophisticated tasks and routines.


At a fundamental level, many of these complicated tasks are based on basic math: addition, subtraction, multiplication, and division.


The same is true for using a computer with audio. Basic math can be used to accomplish many of the ways audio signals are typically processed.



The nice thing about digital audio (compared to analog) is that the math doesn’t get much more complicated than combining together addition, subtraction, multiplication, and division.


Even if math is intimidating to you, don’t worry. The point of using a computer is so a machine will do all the work.


In this section, I will demonstrate how math operators can be used with information stored in a computer.
