Abstract
With the advent of ever more powerful computing hardware, the availability of dedicated GPUs, and realistic 3D displays, visual rendering used in computer games and VR applications have reached a high level of maturity. It is now possible to design computer games and simulations which are progressively more realistic. In addition to being visually pleasing, these developments allowed better navigation and situational awareness visually. However, visual cues can provide only half of what the human brain needs for navigation, spatial coordination and contextual awareness, and is not sufficient by itself. For these tasks to be carried out accurately, the auditory system assumes a role which is at least as important as the visual system. Despite its importance, and despite the existence of necessary technology, auditory aspects of computer games are generally overlooked. Two main areas where audio is essential in computer games are virtual acoustics and synthetic audio. Virtual acoustics techniques are useful in supporting the illusion of being in the virtual environment provided by the game and making it possible to navigate the virtual environment. Cues related to auditory localization of the directions and distances of objects/opponents as well as the properties of the environment can be provided with a pair of headphones or multiple loudspeakers. Synthetic audio techniques on the other hand allow the generation of environmental sounds (such as gunshots, walking sounds, impact sounds, hand claps etc.) related to the context within the game. Virtual acoustics and synthetic audio, will be presented from the computer games perspective in this talk. Current research trends will be reviewed with emphasis on applications of relevant technologies in the computer gaming context.

Short Bio
Huseyin Hacıhabiboglu received the B.Sc. degree from the METU in 2000, the M.Sc. degree from the University of Bristol, U.K., in 2001, both in electrical and electronic engineering, and the Ph.D. degree in computer science from Queens University Belfast, U.K., in 2004. Between 2004-2008, he was a research fellow with I-Lab at the Centre for Communication Systems Research (CCSR), University of Surrey, U.K. Currently, he is a senior research associate at Division of Engineering, King’s College London, U.K. His research interests include audio for games and virtual reality, room acoustics modeling and simulation, audio synthesis, multichannel audio systems, psychoacoustics of spatial hearing, and microphone arrays. He has authored and co-authored more than 25 journal and conference publications in spatial audio and related areas and has a patent on acoustic source separation.
