How to Use a Shotgun Microphone


Shotgun microphones have become indispensable tools for capturing high-quality audio in various settings. Whether you’re a filmmaker, content creator, journalist, or musician, knowing how to use a shotgun microphone properly can significantly enhance your recordings. In this article, we will delve into the world of shotgun mics, how shotgun microphones work, and explore their design, directional capabilities, and best practices for achieving professional-grade sound. 

What is a Shotgun Microphone?

Shotgun microphones, often referred to as shotgun mics, are highly directional microphones designed to capture audio from a specific direction and distance while rejecting and handling noise and other ambient noise effectively. This high directionality makes them a great choice for various applications, from film and video production to recording in small rooms and live events as it reduces a lot of background noise and “accurately” records sound.

Waveform Interference and How It Works on Shotgun Mics

In essence, a shotgun microphone operates on the principle of “waveform interference”. At the heart of it is an interference tube, a long, slender tube with carefully selected slot spacing. The directional polar pattern of shotgun mics is characterized by a narrow, elongated shape resembling the barrel of a shotgun, hence the name. This pattern ensures that the microphone captures sound primarily from the source where it’s pointed directly, making it ideal for isolating a specific source and minimizing background noise.

Desired, on-axis sound will pass straight down the interference tube and be picked up by the capsule unimpeded. At that point, off-axis sounds cancel each other out, while the sound source directly in front of the mic is captured with great precision. In fact, this can either attenuate or blunt the waves coming in from the end of the interference tube in a process called constructive or destructive interference. On-axis sound tends to be enhanced and off-axis sound tends to be attenuated. 

Shotgun Microphone vs Lavalier Microphone

There is a discussion with filmmakers and enthusiasts about when to use a shotgun microphone or a Lavalier microphone for different types of scenes.

A lavalier microphone, also known as a lapel mic, is a small microphone attached to a person to allow hands-free operation. The goal of a lapel mic is to remain hidden while clipped on a person when filming. A lapel microphone also employs an omnidirectional polar pattern, which is opposed to the shotgun microphone. An omnidirectional polar pattern mic picks up sound in a 360-degree radius; it is equally sensitive to it at any angle. This leads to a more natural feel as it doesn’t cut off the sound so abruptly when moving around. 

Using a shotgun microphone or a lapel to capture sound will entirely depend on the needs of the video, whether it is better for it to have a direct, clear sound or a more natural, whole sound. Often, these two mics are used at the same time to provide options and different uses when it comes to mixing. 

In the end, using a shotgun microphone will require the user to point directly at the source for it to record clearly. Its polar pattern allows for an accurate record, with little to no ambiance when attached with accessories. Your search for which microphone will be the most helpful to your project will depend on what your audio needs

How Do You Record with a Shotgun Mic?

There are several ways of using a shotgun microphone. How you will use your shotgun microphone will depend on the activity that necessitates its need. Most of the usage of it will require it to be mounted onto a boom pole. A boom pole is a stick with which your shotgun microphone will be mounted, and a boom operator will hover it over the scene where sound needs to be recorded on set. 

Boom operators often use a combination of the following items: a boom pole, a shock mount, a blimp capsule, a dead cat, and a windshield. These are items usually attached to the shotgun microphone to reduce noise from outside sources. A shock mount is used as a bumper to reduce sounds heard from objects bumping into the microphone. A blimp capsule is used to reduce white noise for quiet indoor videos, a dead cat is used to reduce wind noise when filming outside a closed space, and a foam windshield is attached to the head of the microphone to reduce wind noise when filming indoors. These items all help the clarity coming through the microphone, especially when outdoors.

When there is no boom operator or when you’d like to add support, you may mount your microphone on a C-stand. An example of where this style is used is during interviews when filming takes over a long course of time rather than quick bursts.

Another common tactic when taping your sound source with shotgun mics for film and videos is to directly clip your microphone to your cameras. Having your microphone mounted on your camera and plugged into it improves the sound of the video being filmed tremendously. To add, there are several great options and types of shotgun microphones to consider when using this method: short shotgun microphones are best for close-up shots, while long shotgun microphones are better for long-range shots.

Super shotgun microphones are the most powerful type of shotgun mics and can be used for both close-up and long-range shots. No matter what type of shotgun microphone you choose, ensure the best recording for your projects by properly mounting it to your camera.

What Do You Plug a Shotgun Microphone Into?

Most shotgun microphones require phantom power, typically delivered via an XLR input. It’s worth mentioning that many shotgun microphones require this to operate. This is a low-voltage electrical current supplied by some audio recorders, mixers, or external power supplies. 

This power is necessary to energize the microphone’s internal electronics and ensure optimal performance. Shotgun microphones typically use XLR cables for connectivity. XLR cables are known for their robust design and balanced wave transmission, making them ideal for professional recording. These cables have three pins that connect to the corresponding XLR ports found on most shotgun microphones. 

If you’re looking to record on a computer, you’re going to need an audio interface to get connected. This will also provide the power necessary to operate the mic. You could also connect it to a mixer, or portable recorder. There are several types of audio recorders available, ranging from portable field recorders to digital audio interfaces. Field recorders are particularly useful for on-location recording, while digital interfaces are commonly used in studio settings.

Many YouTubers mount their shotgun microphones on their camcorders or DSLR cameras to improve the standard of their YouTube videos and streams. Cameras often have built-in microphone inputs, usually in the form of a 3.5mm or 1/8-inch jack. In addition to this, YouTubers also track their audio levels with various computer programs that give them access to services to customize their volumes, or add cool and funny filters to their voice when they’re talking.  

Shotgun microphones typically have a frequency response tailored to capture a wide range of sounds accurately. However, it’s essential to check the microphone’s specifications and choose one that suits your specific recording needs, especially if you are recording lower frequencies, such as deep voices or drums. 

Is a Shotgun Mic Good for Vocals?

When it comes to recording vocals, selecting the right microphone is crucial to achieving the desired result. While many microphones are purpose-built for vocals, there’s an ongoing debate about whether a shotgun mic is suitable for this purpose.

Pros of Using a Shotgun Mic for Vocals 


One of the primary advantages of using a shotgun microphone for vocals is its exceptional directional accuracy. The narrow pickup pattern ensures that it captures sound primarily from the front, which can be useful in isolating the singer’s voice from other ambient noises in your filming environment. 

Noise Rejection

Shotgun mics are excellent at rejecting sounds coming from the sides and rear. This can be particularly advantageous in live sound settings or noisy environments, where you want to minimize background noise and interference. 


Shotgun microphones are versatile tools. While they excel in their intended use for film and video, they can also be adapted for vocal recording. Their ability to reject unwanted noise can be beneficial in various scenarios. 

Cons of Using a Shotgun Mic for Vocals 

Limited Naturalness

The narrow pickup pattern that makes a shotgun microphone effective at isolating sound sources can also make vocals sound less natural. Most shotgun microphones are not optimized for capturing the full frequency range and nuances of the human voice. 

Lack of Depth

A shotgun microphone may lack the depth and warmth that dedicated vocal mics offer. Singers looking for a rich, studio-quality vocal recording may find shotgun mics less satisfying in comparison. 

Limited Distance

While a shotgun microphone is excellent for close-miking applications, it may not perform as well when the vocalist needs to move around or when recording a group of singers. 


High-standard mics can be expensive. Investing in a dedicated vocal mic may be a more cost-effective solution for those primarily focused on vocal recording.


Shotgun mics are powerful tools for capturing highly directional audio with exceptional quality. Understanding how to use shotgun mics effectively, including their directional capabilities, mounting options, and accessories, can give you the ability to increase the quality of your recordings, whether you are making films, making music, or producing online content.

With the right techniques and equipment, you can ensure that your audience can hear every word and sound as intended, creating a cool and immersive experience.
