Abstract
Method for spatial filtering of at least one sound signal (M; W(n)) includes the steps of: generation of a first, a second and a third captured sound signal by capturing of the respective sound signals by microphones characterized by directivity patterns of different orders; performing a short-time Fourier transformation of the captured, sound signal s; measuring a cross-pattern correlation or a cross-pattern coherence towards a desired direction ([phi]); calculation of a gain factor (G+) using a cross-pattern correlation based on time-averaged correlation or coherence between the first captured sound signal and the second captured sound signal; and applying the gain factor (G+) to the corresponding time-frequency positions in the third captured sound, signal (; M; W(n)). Independent patent claims also for a system and computer readable storage medium.
