For example, some might be designed in circular fashion to pick up conference meetings, while others may be used for speech recognition or security monitoring. Microphones might serve for voice control of software, computers, and even home automation devices.

While capable of picking up dictations, they are especially useful in noisy environments. Conventional microphones hear sound as one messy signal; they fail to distinguish different sources of incoming sound waves. To compensate, these types limit their reception fields to particular patterns, and rely on intelligent positioning. Array microphones eliminate these issues and essentially create smart virtual microphones that liberate speakers from orientation concerns.

The illusion of space given by the dynamic surround sound of an array microphone makes the technology a popular choice in professional audio environments. Some work independently, while others are organized in groups to provide coverage in large spaces or the individual rooms of a house.

Array microphones are designed to be mounted on large or small arrays, for example for the analysis of sound fields, sound power and transients. Such systems are typically used for measuring and locating noise sources, and here the phase match is important to get good accuracy in the measurements. An important characteristic of array microphones are precisely that the microphones are phase-matched.
