Guy Somberg has been programming audio engines for his entire career. From humble beginnings writing a low-level audio mixer for slot machines, he quickly transitioned to writing game audio engines for all manner of games. He has written audio engines that shipped AAA games like Hellgate: London, Bioshock 2, The Sims 4, and Torchlight 3, as well as smaller titles like Minion Master, Tales from the Borderlands, and Game of Thrones. Guy has also given several talks at the Game Developer Conference, the Audio Developer Conference, and CppCon.

When he's not programming or writing game audio programming books, he can be found at home reading, playing video games, and playing the flute.
