The present invention relates to a system for localizing at least one sou nd source, comprising a set of spatially spaced apart sound sensors to detect sound from the at least one sound source and produce corresponding sound signals, and a frequency-domain beamformer responsive to the sound signals from the sound sensors and steered in a range of directions to localize, in a single step, the at least one sound source. The present invention is also concerned with a system for tracking a plurality of sound sources, comprising a set of spatially spaced apart sound sensors to detect sound from the sound sources and produce corresponding sound signals, and a sound source particle filtering tracker responsive to the sound signals from the sound sensors for simultaneously tracking the plurality of sound sources. The invention still further relates to a system for localizing and tracking a plurality of sound sources , comprising a set of spatially spaced apart sound sensors to detect sound from the sound sources and produce corresponding sound signals; a sound source detector responsive to the sound signals from the sound sensors and steered in a range of directions to localize the sound sources, and a particle filtering tracker connected to the sound source detector for simultaneously tracking theplurality of sound sources.
