Microphones are devices designed for capturing audio. When buying a microphone, pay particular attention to its type, intended use, and also its connectivity to other devices. Professionals should also consider technical characteristics of the microphone, such as impedance, sensitivity, or frequency range.
Microphones transform acoustic energy (sound) to electric energy, and are used in a variety of ways. In this section, you'll find many different microphones according to use or the way they process acoustic signals.
