Abstract:
Methods and apparatus to beamform a first plurality of microphone signals using at least one beamforming weight to obtain a first beamformed signal, beamform a second plurality of microphone signals using the at least one beamforming weight to obtain a second beamformed signal, and adjust the at least one beamforming weight so that the power density of at least one perturbation component present in the first or the second plurality of microphone signals is reduced.
