A boom mic (mounted on a boom pole) is a highly directional microphone used to capture clear dialogue or sound while staying out of the camera’s view. The pole allows audio to be captured close to the subject without appearing in the frame.
Boom mics isolate voices from background noise better than on-camera mics. It captures clean, focused dialogue while giving the camera team flexibility in framing. They’re essential in shoots where wireless mics aren’t practical or desired. The ability to “hover” the mic without being seen makes them versatile and unobtrusive.
Use a boom mic during interviews, narrative scenes, or live-action shoots where you need high-quality, isolated audio. A boom operator must carefully position it just outside the frame to avoid shadows and unwanted visibility. They’re industry standard for film, TV, and documentary production.
Stay just out of frame – Position the mic as close as possible without entering the shot for clean audio.
Monitor handling noise – Use shock mounts and proper grip techniques to minimize pole or operator noise.
Follow the action smoothly – Anticipate actor movement to keep consistent audio levels without abrupt shifts.
