Abstract: A processor-implemented method for spatial sound characterization is described. In one implementation, each of a plurality of source signals detected by a plurality of sensing devices, is segmented into a plurality of time frames. For each time frame, time-frequency transform of the source signals is derived, an estimated number of sources and at least one estimated direction of arrival corresponding to each of the source signals is obtained. Further, source signals are extracted by spatial separation based at least on the estimated directions of arrival and the estimated number of sources, and separated source signals are processed to yield a reference signal and side information.

Abstract: A processor-implemented method for spatial sound localization and isolation is described. The method includes segmenting, via a processor, each of a plurality of source signals detected by a plurality of sensors, into a plurality of time frames. For each time frame, the method further includes obtaining, via a processor, a plurality of direction of arrival (DOA) estimates from the plurality of sensors, discretizing an area of interest into a plurality of grid points, calculating, via the processor, DOA at each of grid points, comparing, via the processor, the DOA estimates with the computed DOAs. If the number of sources is more than 1, the method includes obtaining via the processor, a plurality of combinations of DOA estimates, from amongst the plurality of combinations, estimating, via the processor, one or more initial candidate locations corresponding to each of the combinations, selecting location of the sources from amongst the initial candidate locations.
