Abstract
Time overlapping of acoustic signals, which so often occurs in real life, is a challenge for current state-of-the-art sound recognition systems. In this work, we propose an approach for detecting, identifying and positioning a set of simultaneous acoustic events in a room environment, using multiple arbitrarily-located microphone arrays, and working in real time. Assuming a set of estimated acoustic source positions, the use of a frequency invariant nullsteering beamformer for each position and ...
