Claim:
1. A method comprising: configuring a real-time adaptive microphone array to gather signals from one or more desired directions in a main lobe of the array; configuring the array to reduce side interference gathered from one or more sources of acoustic energy that are not situated within the main lobe of the array; configuring a computer-readable memory to store one or more test signals; processing one or more signals gathered in real time to provide a preliminary output signal and a set of preliminary weights; retrieving the one or more test signals from the computer-readable memory; modeling a degradation in the gathered signals from the adaptive microphone array by applying the set of preliminary weights to the one or more test signals to provide a set of equalizer weights; and minimizing or reducing the modeled degradation in the gathered signals by processing the set of equalizer weights and the preliminary output signal to generate an equalized output signal.
