Lavalier vs Shotgun Microphone: Which Is Right for Video?
On this page
A lavalier is a small microphone clipped or taped to the speaker's chest. A shotgun is a long, directional microphone held on a boom just above the frame and aimed at the mouth. The lav stays close and hidden, so it copes with noise and movement. The shotgun sounds more open and natural but needs a quiet space and someone to aim it. This comparison is part of our video production guide.
| Criterion | Lavalier | Shotgun on a boom |
|---|---|---|
| Sound | Close and clear; chest tone needs EQ | Open and natural from above |
| Placement and visibility | On the body, hidden under clothing | Above the frame, out of shot |
| Noise, echo and the room | Close to the mouth, so less room | Best outdoors and in quiet, soft rooms |
| Movement and risk | Follows the speaker; rustle risk | Must be aimed every line; boom shadows |
| Crew and setup time | Fitting time per person; no operator | Needs an operator or a stand |
Choose a lavalier if
The subject moves, the frame is wide, the location is noisy or echoey, or you have no one to hold a boom.
Choose a shotgun if
You want a natural, open voice, wardrobe can't hide a lav, or several people speak in a controlled space.
Use both if
It's a sit-down interview or anything you can't repeat. Record each mic to its own track and pick the better one in the edit.
How each one sounds
A shotgun on a boom hears the voice from in front of and above the mouth, roughly where a listener would be. That gives a full, open sound with a little of the space around it. Placed about a couple of feet above the head, it sounds natural. Raise it much higher and the voice turns thin and roomy.
A lavalier hears the voice from the chest, below and slightly behind the mouth. That position is close, so the voice is loud and clear against the background. But the chin blocks some of the upper frequencies that make consonants crisp, and the chest adds a slightly boomy tone. Microphone makers recommend correcting this with EQ, or with a lav designed for chest placement. Many cameras and recorders won't do it for you.
On sound alone, a well-placed boom usually wins in a good room. A lav wins when the room is the problem.
Placement and visibility
A lav goes on the body: clipped to a placket or lapel, or taped under one layer of clothing about a hand's width below the collarbone. It can be fully hidden, which suits drama and polished brand films, or left visible on a lapel, which is accepted in interviews and news. Hiding it takes time and depends on wardrobe. Silk, stiff jackets and layered necklaces all make it harder.
A shotgun stays out of frame, above or sometimes below the shot. It never touches the subject, so wardrobe doesn't matter. The catch is the frame line. On a wide shot, the boom has to stay farther away, and the sound gets thinner. On close-ups, it can come right in.
Noise, echo and the room
This is where the two differ most. A lavalier sits a few inches from the mouth, so the voice is much louder than the room. That makes it the safer choice in busy offices, on shop floors and in echoey spaces.
A shotgun's directional pattern helps reject sound from the sides, but mostly at higher frequencies. Low rumble from traffic or air conditioning still gets in. And in small, hard rooms, reflections arrive from every direction, so the narrow pattern can't reject them. The voice ends up hollow or colored. Sound recordists often swap a long shotgun for a shorter, wider microphone indoors, and bring it closer.
Outdoors, with no walls to reflect sound, the shotgun works well, as long as it has a furry windscreen.
Movement and what can go wrong
A lav moves with the speaker, so walking, turning and gesturing don't change the sound much. Its main risk is rustle: fabric rubbing on the capsule or cable, which is hard to remove in the edit. Wireless lavs add batteries, interference and dropouts to the list.
A shotgun has to be pointed at the mouth on every line. Off-axis voices sound dull, so if the speaker turns away or two people talk in turn, the boom operator has to follow. Other risks are a boom dipping into frame, boom shadows from the lights and handling noise from the pole. With an experienced operator, these are rare. Without one, they're common.
Crew and setup time
A lav takes a few minutes per person to fit and hide, and it needs a short sound check, but it doesn't need an operator during takes. That makes it practical for small crews and multiple speakers seated in one place, as long as you have enough channels.
A boom needs a person holding it for anything that moves. For a static interview, a stand can hold the shotgun just outside the frame, which frees the crew. It's quick to set up and doesn't touch the subject, which helps with talent who'd rather not be wired.
Groups change the sums. With four people at a table, lavs mean four fittings, four channels and four tracks to mix, but each voice stays clean. One boom can cover the group if the operator knows who speaks next, which works for rehearsed scenes and less well for open discussion, where people talk over each other.
Plan sound alongside the picture. Where the boom can go depends on the frame and on where you light the interview.
Which should you choose?
For most business video, don't choose: record both. Put a lav on the speaker and a shotgun on a boom or stand just outside the frame, each on its own track. The lav is the safety net for noise and movement, and the boom often gives the more natural voice. The editor picks the better track for each answer.
If you can only use one, match it to the shoot. Pick a lavalier for moving subjects, wide frames, noisy or echoey locations and solo crews. Pick a shotgun for quiet, controlled spaces, for scenes with several people, and when wardrobe can't hide a lav.
If you'd rather have a crew handle sound and picture together, our in-house video production team records, lights and edits every shoot, with no handoffs.
Both are microphone types, not products. Criteria were set before the verdict, and each type is judged on the same five criteria using manufacturer and reference material. No brands or models are rated.
Common questions
Do professionals use lav mics or shotgun mics for interviews?
Often both. A common setup puts a lavalier on the subject and a shotgun on a boom or stand just above the frame, each recorded to its own track. The lav is the safety net if the room is noisy, and the boom often sounds more natural. In the edit, the editor picks the better track for each answer, or blends them.
Can a shotgun mic mounted on the camera replace a boom?
Only when the camera is close to the speaker. A shotgun on the camera is still as far from the mouth as the lens is, so on a medium or wide shot it hears a lot of room and background. It's a big step up from the built-in mic for run-and-gun work, but a boom or a lav close to the speaker will sound cleaner.
Are wireless lavalier mics as good as wired ones?
They can be, and they free the subject to move, but they add things to manage: batteries, interference, dropouts and a transmitter pack to hide. A wired lav is simpler for a seated interview where the subject won't move. If you go wireless, carry spare batteries, check the signal on headphones, and record a backup track wherever you can.
