Abstract
The invention includes a basic approach to simulate the workings of a ribbon microphone based on measurements at an array of more robust small pressure microphones. Embodiments of the invention take an array of microphone elements, either very small microphones that are placed on either side of a printed circuit board or some other device to understand the sound pressure differences from front to back and use those sound pressure differences to emulate the motion of a ribbon if a ribbon were co-located with the array of microphones. The microphone array detects differential pressure, either by a set of elements that that have figure of eight polar patterns, or by having separate elements front and back.
