1. A system for converting sound waves, the system comprising:

  • an array of microphones, the array comprising a plurality of microphones, each microphone of the plurality of microphones comprising;

    a horn portion comprising at least three planar surfaces, the surfaces arranged in a converging orientation to form a shape having a first opening at a proximal end and a second opening at a distal end, the second opening at the distal end being smaller in area than the first opening at the proximal end; and

    an instrument disposed at the distal end of the horn portion, the instrument configured to convert sound waves into an electrical signal;

    the microphones of the array are radially disposed around a central point to define a polyhedron shape and oriented to direct received sound waves to that central point; and

    a beamforming signal processing circuit electrically coupled to each instrument of the plurality of microphones and configured to create a plurality of beam signals based on the respective electrical signals of each instrument.
