Dr. Bruce Wiggins discusses his research into ambisonic mixing techniques that allow for a single audio mix to be reproduced over any speaker configuration, allowing more flexibility than traditional 5.1 surround sound. His work involves developing algorithms to map audio sources to irregular speaker layouts and distance coding techniques. He has applied this research through software plugins and it is being used by companies like Codemasters for video games to save storage space and make audio more reactive to in-game positioning.
