Abstract:

Soundfield imaging is a novel technique for efficiently encoding, representing and processing the wave field captured by a microphone array. Some of the possible applications include source and reflector localization. In this manuscript we discuss the resolution properties of the soundfield image and the trade-offs that need to be considered while designing the “soundfield camera”. Then we propose a source localization algorithm that exploits multiple sound-field images of the same acoustic scene, acquired with different resolutions, to simultaneously localize acoustic sources with widely different distances from the array.
