A shotgun microphone is a highly directional microphone designed to capture sound from a specific source while minimizing background noise. Its long, narrow shape allows it to focus on sounds directly in front of it, making it ideal for film, television, and live events. These microphones are often mounted on a boom pole or used with a camera to record dialogue or sound effects from a distance. The design helps to isolate the desired audio, ensuring clarity and reducing interference from surrounding sounds, which is crucial in noisy environments.
