There are five principal individuals overseeing the music and audio for Age of Conan: Hyborian Adventures. The Audio Director is Morten S?rlie, who created the widely hailed soundtrack for Anarchy Online - Shadowlands. Simon Poole (Lead Sound designer on "Dreamfall - The Longest Journey") took over as Audio Director in May 2007, and saw the project through to completion. The sound designer are Tord D. Nikolaisen and Fredrik Martol, and composer Knut Avenstroup Haugen who is writing the musical score for the game. To create a fitting musical score for the Hyborian universe, composer Knut Avenstroup Haugen turned to many different sources: For the music of the different ethnic groups, Haugen studied traditional music from relevant parts of the world. For the overall sound of the Hyborian Age, Haugen studied ancient- and medieval music as well as the romantic orchestra repertoir and film scores, while avoiding conventions that connect too closely to specific historical periods. The female vocalist throughout the soundtrack is the Norwegian singer Helene B?ksle. Norwegian death punk artists, Turbonegro, contributed three songs as well.
