So you want to make a video. You’ve done all the prep work, and now it’s time to film. Not only do you have to consider the quality of your video production, you have to consider your audio production as well. You can’t have high-quality video without high-quality sound to match. And in most cases, high-quality sound is more important than high-quality video. Treat your audio with just as much or more importance as your video and you’ll be sure to have a video of the highest audio and visual quality. With just a few tricks, you can manage the sound and elevate the audio on your video.

Choose the Right Mic for the Job

Though it may be tempting, you can’t rely on just one type of microphone for everyone of your filming jobs. Different types of microphones have different strengths when it comes to capturing audio in a given situation. The shape and size of a microphone can have a tremendous impact on the quality of your audio. Not to mention other factors such as portability and the ability to adapt in louder environments.

Common Types of Microphones

  • Shotgun. A shotgun microphone is a highly directional microphone that must be pointed directly at its target sound source for proper recording. It is used for talks or speeches in meetings, conferences, and lectures.

  • Handheld. A handheld microphone is any microphone held in the hand and used to pick up human speech. They are used in a variety of settings, from musical performances to television interviews.

  • Wireless. A wireless microphone is a microphone without a physical cable connecting it directly to the sound recording or amplifying equipment with which it is associated. They are mainly used to allow public speakers, interviewers, performers, and entertainers to move about freely.

  • Boundary/PZM. A boundary/PZM microphone is a type of condenser microphone that eliminates the interference of reflected sound waves. It is mostly used in conference situations.

  • Stereo. A stereo microphone is two regular studio microphones in a single unit. It can be used to create a sense of width in recording.

  • Wired Lavalier. A wired lavalier is a small microphone used for television, theatre, and public speaking to allow for hands-free operation. They are most commonly provided with small clips for attaching to collars, ties, or other clothing.

Microphone Placement

Once you find a the microphone that best fits your filming needs, you want to make sure you place your microphone in the right spot to pick up your audio. Managing sound through the right placement can make all the difference in the quality of your audio. You want to make sure to place your microphone within proper distance of your subject. Too far and it will pick up echo, but too close, and you might end up with a grainy sound.

Avoid Problematic Audio Environments

If possible, manage your sound quality by scoping out shooting locations prior to filming. Bring your camera, microphone, and a good pair of headphones, preferable around the ear, to identify problem noise sources.

Oftentimes, what you hear through headphones is very different than the naked ear. Even something like an air conditioner can sound drastically different through a microphone than just on its own. You want to choose a location that has as little background noise as possible so it doesn’t detract from what you’re filming.

Conversely, you don’t want to pick a location that has too much echo, as it will skew your audio. The key is to pick a filming location that has enough sound balance to where you can edit it out or tone it down in the editing process.

Wind and Weather Protect Your Microphone

Sometimes you can’t control the weather, especially on a shooting day. While you run the risk of ruining your equipment because of the elements, you also run the risk of ruining your audio. On days you shoot out in the weather, make sure to invest in some heavy wind and rain protection for you audio equipment. Don’t skimp on the quality of your weather protection equipment. If the mic picks up even the slightest of breezes or sprinkling of rain, it can make your work unsuitable to use in the final product. Take preventative measures ahead of time to ensure that you still are able to produce high-quality sound — even in the most inclement of conditions.

Capture Audio Using a Separate Recorder

When dealing with recording audio on a video camera, you run the risk of the audio not being of the same quality as the video. Some cameras maintain the recording levels at a particular level so you don’t always have control over the sound, especially in the editing process. Unless you are making a silent film, you should place just as much emphasis on your audio as you do on your video, making sure you achieve the highest quality possible. By using a separate audio recorder, you can better manage your sound to achieve superior audio results. It may be a hassle when it comes to filming, but you will thank yourself when it comes time to edit the project and your audio is exactly how you want it to be.

It’s easier than you think to match up audio recorded separately from the camera. If you are using editing software such as Adobe Premiere, you will be able to access a function that matched waveforms. If you want to go more old school, during the filming process, you can use a combination of a clapper and note-taking. This method will allow you to locate and matchup audio quickly in post-production.

Use Hardware Compressors and Limiters for Indoor Filming

While filming inside limits the risk of exposure to outside noise, other factors can make it difficult to create a quiet environment. Particularly in the case of doing voice overs, you may want to consider investing in hardware compressors and limiters, which smooth out the sound and allow you to get more level to your recorder. This will cut down any extra noise that you may have around you and make for high-quality audio. A tool like this is commonly used outside the studio to limit the noise in an outdoor filming location, but don’t be afraid to try it inside to experience the wonders of what it can do for your sound.

Sound Triumphs at Sundance

Tangerine”, a breakout hit from the Sundance Film Festival in 2015 was shot completely using an iPhone 5S. Because of budgetary constraints, director Sean Baker turned to an iPhone as his recording device of choice. The filmmakers like the portability and flexibility of the device to get the shots they desired for the film. Though it was using a device most of us already own, the filmmakers and directors still needed to know principles of cinematography, including sound.

When filming “Tangerine,” they used additional tools and apps to alter the visual quality of the film, but didn’t need to do anything to alter the sound that was captured on the iPhone. As a result, they were able to make a hit on a shoestring budget while still producing a film with high-quality audio and video.

Sound might be one of the hardest aspects of filming to get right. It takes a lot of trial and error, and perseverance to find the right equipment and environment that work for you and your project. By mastering a few of these tricks, you will achieve high-quality sound every time.

  1. I never knew that the size and shape of a microphone could affect the quality of your audio tremendously. With this in mind, I would assume that those who need to have their music produced could consider hiring an audio production company. I could imagine how a professional company would have access to important tools and equipment to ensure quality audio outputs.
