Abstract:
Embodiments include a method and an apparatus for the localization of at least one source of an acoustic signal including: temporally sampling the acoustic signal with a plurality of microphones to obtain a (D+1)-dimensional space-time matrix representation of the acoustic signal, wherein D is the number of spatial dimensions, applying a (D+1)-dimensional Fourier transform to the matrix representation, determining a first peak in a spectrum obtained based on the application of the Fourier transform, and calculating the direction of arrival of the acoustic signal at at least one of the plurality of microphones based on the determined first peak.
