Boom microphone

Definition

A boom microphone is a type of directional microphone mounted on a boom pole that allows sound recordists to capture audio from a distance while keeping the microphone out of the camera frame. This setup is essential in film and television production, as it helps to isolate sound sources and reduce unwanted background noise. The design ensures that the microphone can be positioned closer to the sound source, improving audio quality without intruding on the visual composition.
