1. A method of processing audio signals from a plurality of microphone cartridges into an audio output signal, the method comprising:
receiving, by a processor, an audio signal from each of the plurality of microphone cartridges, wherein the plurality of microphone cartridges are adjacent to one another;
delaying a first pattern signal to produce a delayed first pattern signal, wherein the first pattern signal is produced based on the audio signals of the plurality of microphone cartridges;
phase shifting a second pattern signal to produce a phase shifted second pattern signal, wherein the second pattern signal is produced based on the audio signals of the plurality of microphone cartridges; and
summing the delayed first pattern signal and the phase shifted second pattern signal to produce a toroidal audio output signal.
