Digital Recording

Computers have made it easy to create digital recordings. A simple home computer costing as little as $600 can be used as a digital recorder. Companies like Sony and Panasonic have created small digital recorders who's quality is equal to that of CD Audio. If you look in a store where telephones are sold, you will find that most answering machines are now all digital. All it takes to experiment with digital audio is a computer, sound card, software, and an input device like a microphone.

With the addition of a CD ROM Recorder (CD-R) you can make your own Audio CDs of your digital recordings.

In this chapter you will learn the basics of digital techniques for generating and recording sound.
