Organisation profile

The research lab was founded in 2012 and is located at the Dept. of Architecture, Design & Media Technology at Aalborg University in Denmark. It is headed by Associate Professor Mads Græsbøll Christensen and is comprised of a group of researchers who conduct basic and applied research in signal processing theory and methods aimed at or involving analysis of audio signals. The research focuses on problems such as compression, analysis, classification, separation, and enhancement of audio signals, as well as localization, identification and tracking using microphone arrays. The lab and its members are currently funded by grants from the Villum Foundation, the Danish Council for Strategic Research, and the Danish Council for Independent Research.
