Chapter eight of the text Sound and Recording by Francis Rumsey and Tim McCormick, discusses the principles of digital audio, and contrasts digital with analog. The text also illustrates how digital and analog work together to produce desired sound.
In the world of audio there are two types; digital and analog. Analog can be described as physical or tangible in a sense, being etched onto some type of media. Digital however, is a representation of the audio waveform, which is converted into a sequence of binary numbers. Each of those numbers represent the amplitude of the signal at a certain point in time. The numbers are then coded to allow the system to recognize whether a signal is correct or incorrect. Wanted and unwanted sounds become
