What is microphone array?

A microphone array is a group of multiple microphones placed in close proximity to each other to capture sound from multiple directions. The primary purpose of a microphone array is to enhance the directivity and sensitivity of the system, allowing for better sound capture and noise reduction in various applications.

Microphone arrays are commonly used in speech recognition, surveillance systems, teleconferencing, and acoustic beamforming. They can be either linear or circular in configuration, with each microphone in the array capturing sound signals that are then processed and combined to create a more accurate representation of the sound source.

One of the key advantages of using a microphone array is its ability to distinguish between desired sound sources and background noise, leading to clearer and more accurate audio recordings. Additionally, microphone arrays can help in localizing sound sources and identifying the direction from which the sound is coming.

Overall, microphone arrays offer a versatile and effective solution for improving audio capture quality in various applications, making them a valuable tool for sound engineers, researchers, and technology developers.
