1. A computer implemented method for maintaining spatial stability of a sound field comprising:

  • calculating balance gains for each of two or more microphone signals;

    calculating one or more signal values for each of the two or more microphone signals;

    detecting structured noise content for each of the two or more microphone signals;

    mixing a first microphone signal of the two or more microphone signals with a second microphone signal of the two or more microphone signals responsive to the detected structured noise; and

    gain adjusting the two or more microphone signals, including the mixed first microphone signal and second microphone signal, responsive to the calculated balance gains and the one or more signal values for each of the two or more microphone signals.
