Outline of Final Research Achievements

Realistic sound propagation significantly improves the sense of presence of users, and it is indispensable in human-computer interaction and realistic communication. This research investigated a hardware-accelerated sound field rendering system by co-designing algorithm and architecture, and explored the architecture extension to investigate a generic accelerated platform to solve sound/wave propagation problems in other domains. The new rendering algorithm was studied to reduce computations and memory demands, and the novel accelerated system was developed to speed up computations. In addition, the technology of achieving high-fidelity auditory perception in large-scale sound environments was explored.
