Squarehead Technology provides advanced microphone array systems for audio capture and acoustical zoom. A microphone array  combines a large number of individual microphones to create a highly directional audio output.  The challenge of isolating and capturing desired sound in noisy environments is a well-known problem. Our products allow an operator to zoom in on a particular area and record sound in much the same way a camera zooms in a scene. This is achieved by using sophisticated digital signal processing of audio from several hundred microphones combined into a single system. All audio channels are high quality digital signals that can be recorded without any loss.
