Today there are talking toasters, cars that start themselves using voice recognition, and telephones that use voice commands. But those are not the only examples of digital sound. The ubiquitous earbuds and tiny MP3 players show how common it is to listen to digital music. Digital Music: Computers That Make Music examines digital sound's basic principles, history, physics, and different formats and how it became so prevalent in the digital world. Because the Internet has made it so easy to share digital files, this volume includes a discussion of the legal implications of sharing music and other files. This accessible title also considers some of the possible trends in the future of digital music.
