Audio and acoustic signal processing

This theme centers on theoretical foundations and algorithms for audio, acoustic, and speech signals. The main research areas currently covered are multimedia data compression (speech, audio, video), single- and multi-channel speech enhancement, signal processing for large-scale sensor networks (localization, distributed signal processing), signal processing for hearing aids, and acoustical signal processing.

The audio and speech processing group has tight connections with industry (sponsored research), e.g., Google, Huawei, Bosch, Bang & Olufsen, Oticon A/S, Philips, etc.
