Lesson 3 - Digital Audio

Even before the introduction of the Compact Disc, digital audio started to shape the sound of popular music, as digital effects processors, samplers/sequencers, and digital synthesizers started to appear on commercial records as early as the mid 1970s. The evolution of computer-based technology was gaining tremendous momentum, and digital processing began to creep into every aspect of music production. By the 1980s, the digital revolution was taking the music industry by storm. Digital instruments, digital recorders and digital consumer audio formats were taking over the audio world. Over the course of roughly the next two decades, digital audio began replacing analog audio in almost every application. While Pro Tools has become the industry standard for recording, and the MP3 has become the standard listening format, the world of digital audio has had an amazing evolution, and its story continues to unfold. In this chapter, we will take a closer look at how digital audio works, different digital audio recorders, how digital audio is used to make music, and digital audio formats.
