“Sonifying Processing: The Beads Tutorial” shows students and artists how to bring sound into their Processing programs. Veteran sound artist Evan X. Merz introduces the black art of audio in Processing through the versatile and easy-to-use Beads Library. The topic of audio is largely absent from other Processing books, but “Sonifying Processing” shows that Processing is a powerful multimedia platform that rivals Max. Each section of the book explains a sound programming concept then demonstrates it in code. The examples build from simple synthesizers in the first few chapters, to more complex sound-manglers as the book progresses. Each step of the way is examined at a level that is simple enough for new learners, and comfortable for more experienced programmers.
