While video quality matters, sound quality is equally as important — often differentiating amateur and professional content. In this article, we’ll discuss various shotgun microphones to capture the best audio possible for seamless pairing with your video. The guidelines offered here will help you achieve high-quality sound by choosing the best shotgun microphone for your work.

What is a Shotgun Microphone?

Shotgun microphones are directional and pick up sound that’s directly in front of them while, at the same time, reducing noise coming from other directions. Microphones of this type are sometimes called interference-type line microphones because they’re highly sensitive. For this reason, you must aim the microphone at the sound source in order to record it. This means you can concentrate on what you’re saying without worrying if the microphone will pick up any supplementary sounds. 

You can get the best sounding recordings for your video content with a boom mic or a longer shotgun-style mic if you’re in a controlled environment. A “boom mic” is essentially a boom pole-mounted shotgun mic. These are the best way to record audio since they sound the most natural right out of the box. Although they are most commonly on film sets, they’re perfect for interviews and content creators who do things solo.

What is a Shotgun Mic Used For?

Shotgun microphones are an excellent choice for voiceovers, live event coverage, streaming, foley, and location sound capture. For instance, an interview is a perfect example of needing to capture people’s voices clearly without background noise.

What is the Difference Between a Shotgun Mic and Other Mics?

The term “shotgun” refers to the polar pattern of the microphone. Most shotgun microphones are hyper-cardioid patterns. This means the microphone is very directional, so you can point it at a specific subject and it will only pick up their voice.

Dynamic microphones and condenser microphones are two types of mics based on their capsule components and mechanisms. Generally speaking, dynamic microphones are less sensitive but more robust and best used on loud sources. Meanwhile, condenser microphones are more sensitive to small changes but can be overloaded if the source is too loud.

The quality of rejection is as important as the degree of rejection. Even a highly directional shotgun will admit off-axis sound at certain frequencies. When this audio is colored by comb-filtering artifacts, your end result will be affected. Most shotgun mics are reasonably good at capturing on-axis audio. Although, for the best overall audio, it’s important to look for low-self noise and high sensitivity in conjunction with a natural on-axis sound and uniform off-axis rejection. 

In general, most shotgun mics require 48V phantom power from a mixer while other on-camera versions and capsule mics use the camera’s internal power, or have a removable battery. Shotgun mics are a great choice if you need to speak from a distance and don’t want to hold a dynamic microphone or wear a lavalier microphone. 

Shotgun vs. Lavalier

Both shotgun mics and lavaliers (lapel mics) can capture quality audio when used properly. They are perfect for interviews, vlogging, and dialogue. Since lavalier mics clip to the subject, even the omnidirectional variety can provide a good signal-to-noise ratio. A wired lavalier mic can be plugged directly into a 3.5mm jack and record directly to the video file. Wireless lavalier mics require a transmitter, which can also be plugged into 3.5mm or recorded to a separate mixer to sync up later in post-production.

Despite lavaliers being suitable for a ton of things, the form factor of a shotgun mic make them more versatile. When compared to lavaliers, shotgun microphones can sound more natural. Also, they can be kept out of your shots without needing to be hidden on actors, yourself, or interviewees.

How Far Can Shotgun Mics Reach?

That all depends! A shotgun mic is much longer than a typical microphone. This is why they are reassembled as shotgun. The practical range is the most important factor to consider when choosing a mic. A shotgun mic typically has a pickup range around four to ten feet.

Generally, a medium shotgun works well enough for booming and picking up voices. Although a short shotgun microphone is less directional than its longer siblings, it still provides better rejection of off-axis high frequencies than a hyper-cardioid microphone. 

Longer tubes will reject more off-axis sound, but they are also more difficult to work with due to their length. Since moving the microphone even slightly off-axis will result in attenuation of the sound source, this microphone is quite sensitive to positioning and requires a fixed mic/source or a skilled boom operator. Often, this is the best option for loud environments.

Where Should I Aim the Shotgun Mic?

Since shotgun microphones are directional, they’re excellent for capturing natural sounding dialogue. Just aim it at the chin or upper chest, stay about 2-3 feet away from the subject’s mouth, and pay attention to your frame so the mic doesn’t end up in the shot. It’s common to record dialogue above your talent, but you may also record it below your talent depending on the situation. Experiment with what works best and sounds great.  

The capsule-style mics on cameras are pretty directional. You’re going to hear what you point them to more than anything else. You should aim to record about three to four feet (one meter) away from your subject. When handling your camera, on-camera capsules and shotgun microphones come with built-in shock mounts to protect them from vibrations, shocks, and wind that may rush across the end capsule. These types of mics are great for grab-and-go content creation.

Shotgun Mic Options 

Sennheiser MKE 200 Super Cardioid On-Camera Microphone

This is a directional on-camera microphone with built-in wind protection and shock absorption for enhanced in-camera audio. It includes 3.5mm TRS and TRRS coiled cables for compatibility with DSLRs and mirrorless cameras.

  • Directional microphone for improved in-camera audio
  • Stylish and compact design
