| Outline of Research at the Start |
This research investigates a hardware-accelerated sound field rendering system by co-designing algorithm and architecture to offer real-time rendering, and explore the architecture extension to develop a generic accelerated platform to solve sound/wave propagation problems in other domains. The new hardware-oriented low-dispersion rendering algorithm is studied to reduce computations and memory demands, and the novel accelerated system is examined to speed up computations. The technology of achieving high-fidelity auditory perception in large-scale sound environments is explored.
