Live Sound Lesson 4 – Digital Audio
Let’s unpack that term, shall we? Digital audio refers to an electrical voltage that’s turned into binary data that a computer can understand through a series of ones and zeros. If that sounds at all daunting, don’t worry! We’ll break it down for you in a way that makes sense. By understanding the foundations of digital audio we’ll be better at manipulating the audio signal in a host of various circumstances and applications. Digital audio refers to an electrical voltage that’s transferred into binary data that a computer can understand. Don’t worry about understanding all this on a scientific level. We will still be able to make music while these concepts are percolating within our minds. We’ll always bring it back to the “hows and whys” behind what we are doing. The standard number system used in your everyday life is called a “base 10 number system.” Binary code uses only two values—0 and 1. Zero is obviously the lowest value and one is the highest value. Let’s take a look at how these number systems function.
