WILMA - Wireless Large Scale Microphone Array

Everyday situations are rich in numerous acoustic events emerging from different origins. Such acoustic scenes may comprise discussions of our fellow human beings, chirping birds, cars, cyclists, and many more. So far, no recording or scene analysis technique for this rich and dynamically  changing acoustic environment exists, though it would be needed in order to document or actively shape an acoustic scene. We know customized  techniques for recording symphony orchestras with a static cast, but none that automatically readjusts to scenes with varying content. Thus, a new recording technique, that analyzes the signal content, the position and the  activity of all sources in a scene, is feasible. The wireless large scale  microphone array (WiLMA) is the mobile infrastructure at the Institute of  Electronic Music and Acoustics (IEM) that allows for investigating into new recording and analysis techniques.

This project was partly funded by the MINT/Masse program of the Federal Ministry of Science and Research.
