Pro Tools has remained an industry standard for engineers and producers in the professional studio environment, as well as for the novice music enthusiast, for more than 20 years. In this chapter, we will begin to scratch the surface of this very ubiquitous DAW. Today, Pro Tools is owned and operated by Avid, an American technology and multimedia company based in Burlington, Massachusetts but Pro Tools progenitors are Peter Gotcher and Evan Brooks of Digidesign. First introduced as Sound Tools in 1989, Gotcher and Brooks had become known for the sounds they created which were far superior to what was available at the time. For nearly 30 years, Digidesign, now Avid Audio, has been the industry leader in digital audio production, providing the professional music, broadcast, multimedia, and film industries with tools for audio creation, post production, collaboration, and distribution. Their innovative core technologies, which continue to revolutionize the audio profession and the art of recording, have earned them a Grammy award for Outstanding Technical Achievement. They also got an Oscar statuette representing the Scientific and Technical Award of the Academy of Motion Picture Arts and Sciences for the design, development, and implementation of the Digidesign Pro Tools digital audio workstation.
