Claim One:
1. A method, comprising: receiving a sound input with a plurality of sound input sensors, the sound input comprising a target signal from a source and noise from at least one interferer; transforming the sound input into a frequency domain form represented by a plurality of different frequency bins; determining a plurality of recovery-filter weight sets as a function of kurtosis, each recovery-filter weight set corresponding to one of the frequency bins; determining a plurality of steering vectors, each steering vector corresponding to one of the frequency bins and one of the sound input sensors; determining a plurality of beamformers according to the steering vectors and the recovery-filter weight sets, each beamformer corresponding to one of the frequency bins; and providing an output signal representative of the target signal as a function of the sound input and the beamformers.
