Ever watch a low-budget movie and wonder, “How did this film make the cut?” The cinematography may have been average, the story derivative but — the sound! The quality of the sound design may be the reason the film made it onto the screen. Surprisingly, many film festival programmers rate sound quality as the element they weight most heavily when looking at entries. In fact, sound in cinema can be very deceptive. Having the best microphone possible is an important element in achieving good sound.
Techniques that many films use — such as audio editing, ADR (automated dialog replacement, also known as dubbing or looping), remixing and sound sweetening — occur in post-production and can be very time-consuming as well as expensive.
Because sound plays such an important role in audience perception, it’s important to get the audio right. That means you need the right microphone for the job. Here are our picks for the best microphones for video production in several categories. At the end of the list, we’ll go over the most important factors to consider as you shop for your next mic.

- Suitable for adverse environmental conditions
While not a small investment, the Sennheiser MKH-416 Short Shotgun Interference Tube microphone is an industry-standard that can be spotted on Hollywood sets and professional independent productions alike. The mic is responsive to frequencies between 40 and 20,000 Hz and has a hypercardioid pickup pattern that begins to narrow into a lobar pattern above 2 kHz. This particular microphone has extremely powerful directivity meaning you will always get an incredibly tight and focused recording, no matter where you’re recording.
When your work takes you outdoors, you’re bound to encounter humidity and condensation, which can cause many mics to fail. The MKH 416-P48U3’s RF condenser design makes it highly immune to moisture, allowing you to reliably capture high-quality audio in normal and adverse environmental conditions. The MKH 416-P48U3 also has a foam windscreen to reduce unwanted wind noise.
Designed specifically for film, radio and television work, the MKH-416 has a durable all-metal body ready for hard use on set or on location. It’s expensive but the MKH-416 is a quality product that you can rely on.
Best camera-top microphone
Røde VideoMic NTG
- Safety channel
- Long battery life
- Rechargeable battery
- Larger than previous models
Røde’s NTG shotgun microphones are typically known for being lightweight, on-the-go microphones capable of delivering broadcast-quality audio. The VideoMic NTG offers everything that we’ve become accustomed to in the NTG series, combined with features from the VideoMic lineup.
The VideoMic NTG can be used in many different setups: on-camera with DSLRs or smartphone rigs, on a boom pole or as a USB mic for recording voiceovers, podcasts or live streaming.
This mic has a highly directional super-cardioid polar pattern and infinitely variable gain control. Users are able to adjust the mic’s output from mic level to line level to headphone level. There is also an Auto-sensing 3.5mm output that automatically switches between TRS and TRRS. It would work for both cameras (TRS) and mobile devices (TRRS). No need for adaptor cables.
The VideoMic NTG has a high-pass filter (75Hz or 150Hz), – 20dB pad, high-frequency boost, and safety channel. Additionally, the switchable safety channel records an additional channel at -20dB if the main channel just so happens to clip.
The microphone uses the Rycote Lyre shock mounting system with cable management. Also, it works with a sliding rail mount.
Best Budget Microphone
- Roll-off positions switch
- Solid construction
- Battery or phantom powered
- Extra-long form factor
The Audio-Technica AT8015 Shotgun has proven to us it is currently the best budget microphone, offering the most features for the lowest price.
To give you an overview of this mic, the Audio-Technica AT8015 Shotgun is a line gradient condenser, phantom or battery-powered, shotgun mic. It’s primary focus is to capture over long distances. It is positioned to do that thanks to its sound rejection design, rejecting sound coming from the sides and the rear. With its ability to capture sound from long distances, it can be used in a number of situations. Those working in TV broadcasts can use it to capture audio of a news reporter or interviewee. Also, those working on professional or personal video projects should be able to use this mic to capture audio clearly without having to get the mic in the shot. Its versatility at a low price is one of the reasons it is the best budget microphone out there right now.
Additionally, the AT8015 Shotgun features a roll-off position switch. What does this switch do? It reduces the pickup of low-frequency ambient noise. So, for instance, the mic will cancel out anything like traffic, room reverberation and mechanically coupled vibrations.
Factors we considered
The best microphone is the right one for your shooting situation. To get a better idea of how to choose the right mic, let’s take a look at some key specs.
The first thing you’ll need to consider is form factor. There are several basic types of microphones you can use in production.
Whether wired or wireless, handheld microphones are held by an interviewer or talent. They’re great for getting run-and-gun interviews in noisy environments where you don’t have the time for a lavalier. Handheld mics can also be used on a stand to pick-up audio from a subject who will not be moving around. Handheld mics can deliver a very rich full sound. However, if you don’t want your microphone in your shot, a lav or shotgun mic would be a better option.
This tiny microphone clips to a lapel or shirt, or it can be completely concealed under the talents’ clothing. Lav mics come in both wired and wireless forms. Lav mics can be helpful at times in blocking outside noise because of their close placement to the sound source; however, the noise created by your subject’s clothing moving around while wearing a lav can make the audio captured by the microphone unusable. Lavalier mics typically don’t produce as rich of a sound as handheld or shotgun mics. If it’s possible, use a shotgun mic instead of or in addition to the lav.
This long, thin type of microphone mounts to a stand, boom pole or your camera rig. Shotgun mics can be placed much further away from your subject than lavs or handheld mics, while still doing a good job at rejecting outside noise. Shotgun mics are sensitive to handling noise, however, which can make using one mounted to a camera rig, or even on a boom pole, challenging.
Microphones in post-production
Microphones used for ADR or narration vary from handheld mics to large condenser mics. While many have XLR outs to connect with pro audio gear, many are now being built to connect directly to computers via USB. Foley — the background sounds in film and TV productions — is often recorded with a large variety of mics depending on many variables, including whether the recording is in a studio or outside and what the desired sound is.
Need-to-know tech specs
This is a quick and dirty breakdown. It’s important to note that audio recording is an art unto itself, similar to cinematography. Many chapters of many books have been written about types of microphones, construction of mics and their pickup patterns.
Condenser vs. dynamic mics
The design of a microphone element or capsule will affect how the mic performs. There are many types of microphone elements; however, due to cost, durability and function, there are only two that should be considered for production and post: condenser and dynamic.
In the most basic sense, condenser microphones use electrical current to power a series of plates that vibrate when sound waves hit them. The obvious con to this type of microphone is that it needs power at all times in order to work. Pro audio systems use phantom power to send power down the microphone cable to condenser mics without interfering with the audio signal. Otherwise, the mic will need a battery.
Condenser mics can be very sensitive, allowing them to pick up audio from a distance. A good example of this use is shotgun microphones. This same sensitivity can result in a condenser mic picking up a lot of extra wind noise and background noise. That’s why a good windscreen is also a vital accessory for your shotgun mic. It’s also important to note that condenser mics can be a bit delicate.
Dynamic microphones are the most rugged mics available.
Dynamic microphones use an electromagnetic coil and diaphragm. While that may sound a lot more delicate than a condenser, it’s not. Dynamic microphones are the most rugged mics available. They do have a limited sensitivity, which actually is not always a downside; however, dynamic microphones don’t usually have as tight of a polar pattern as many condenser mics have.
Polar patterns, also commonly known as pickup patterns, are the areas that a microphone will be sensitive to sound. The common polar patterns used in production recording mics are omnidirectional, cardioid, hypercardioid, supercardioid and line. Some microphones can even switch between polar patterns.
An omnidirectional mic has a polar pattern that is round in shape, while a cardioid polar pattern is heart shaped. The line polar pattern used for shotgun mics is almost completely in front of the mic and very directional. This helps explain the shotgun’s rejection of noise along the sides of the mic and its popularity for use on film shoots.
Lav and handheld mics commonly use cardioid and hypercardioid patterns. They offer a good balance between wide pick up and rejection of outside noise.
Perhaps the most overlooked element when shopping for a new microphone is frequency response. This is a measurement of the audio frequencies a microphone is most sensitive to. This is usually expressed in Hertz (Hz). Each model will have a different frequency response, so you’ll need to know how you plan to use it. For example, if you record only spoken word, you only need a microphone that has good reproduction down to around 75Hz. Most people’s voices when speaking are not any lower than that. On the other hand, many audio engineers feel that accurate reproduction of up to and in excess of 15,000Hz (15kHz) is important for good intelligibility and a feeling of clarity of the spoken word.
Wireless vs. wired
As a rule, wired microphones are more reliable than wireless; wireless always runs the risk of having radio frequency interference. There are new wireless systems that help eliminate many of those interference issues, making the difference more about money. Wireless systems are typically much more expensive.
Adjusting to the situation
The right mic for the job may be using more than one microphone. For instance, say you’re doing an interview on the sideline of a football game using a handheld mic. You can hear the subject holding the mic but not the crowd behind him. If you see the crowd making a lot of noise behind the subject of the interview but can’t hear the crowd making noise, it’s going to be rather awkward for viewers. In this case, record from a pair of microphones. You can use the built-in mic on your camera to pick up the crowd while the handheld mic picks up your subject. This gives you the ambient sound of your location without overpowering the track from your subject in your mix.
The right mic is only half the job.
Once you’ve determined the right mic(s) for a job, you’ll need to focus on microphone placement. Sound experts have written entire books on microphone placement for recording. Taking the time to learn mic placement techniques will likely improve your audio more than better gear.
Many microphones require accessories such as a windscreen, pop filter, zeppelin, shock mount or even a boom pole. Purchase them with your mic so you don’t find yourself facing an overnight shipping situation. Remember also that proper placement of your new microphone can make a huge difference.
Don’t settle for acceptable audio when you can have sensational sound.
