Drawing on decades of experience, Beep to Boom: The Development of Advanced Runtime Sound Systems for Games and Extended Reality is a rigorous, comprehensive guide to interactive audio runtime systems.
Packed with practical examples and insights, the book explains each component of these complex geometries of sound. Using practical, lowest-common-denominator techniques, Goodwin covers soundfield creation across a range of platforms from phones to VR gaming consoles.
Whether creating an audio system from scratch or building on existing frameworks, the book also explains costs, benefits and priorities. In the dynamic simulated world of games and extended reality, interactive audio can now consider every intricacy of real-world sound. This book explains how and why to tame it enjoyably.
