1. A method for receiving audio at a microphone comprising:

  • determining a fixed coordinate systemidentifying a position of the microphone relative to the fixed coordinate system, where the microphone includes a plurality capsules;

    receiving audio signals representative of at least one sound source, where each of the capsules generates an audio signal;

    analyzing the audio signals based on the known positions of the microphone and capsules in the fixed coordinate system;

    adjusting a direction of at least one of the capsules based on the analysis of the analyzed audio signals received at that at least one capsule;

    providing an identification of a principal direction of the microphone, where the principal direction of the microphone is known relative to the fixed coordinate system; and

    adjusting the identification of the principal direction of the microphone based on the analysis of the analyzed audio signals, where the identification comprises a light source that illuminates a direction of the microphone.
