Project

Distributed Digital Signal Processing for Ad-hoc Wireless Local Area Audio Networking

This project aims at conceiving a novel digital signal processing (DSP) framework to encourage the development of a next generation of speech and audio systems and devices, capable of exploiting wireless connectivity for enhancing acoustic signal capture and playback. A wireless local area audio network (WLAAN) is envisaged, in which different user devices can seamlessly cooperate to solve device-specific or joint DSP tasks by efficiently sharing signals and resources. The spatially distributed and ad-hoc nature of the envisaged WLAAN creates opportunities in terms of improved acoustic field sampling and high signal-to-noise ratio audio capture, but at the same time brings challenges in terms of network processing, distributed processing, algorithms interaction and acoustic modeling. By addressing each of these challenges, the project is anticipated to create a significant leverage effect for future developments in different segments  of speech and audio industry.
