A functional model of planar microphone array realized with low-cost microphones

This paper describes a realization of microphone array designed on initial assumption to incorporate low-cost multimedia microphones and standard laboratory equipment. Mechanical construction of the array is made of components find on market and some second-hand mechanical parts found in laboratory. Special preamplifiers were realized to work with wide range of low-cost microphones. Paper also presents subsystem designed for amplitude and phase aligns of the low-cost microphones in the array.
