Essential Audio Techniques for Crisp, Professional Sound in Interviews

August 12, 2025

You can color grade footage, reframe a shot, or clean up lighting but you can’t save bad audio.

When it comes to video interviews, sound is half the experience, and the fastest way to lose trust is with a tinny, echoey voice or background noise that makes your message hard to hear. At 3Motion, we treat audio as seriously as we treat the lens. Because what your audience hears matters just as much as what they see.

Here’s how we capture clean, professional sound in every interview we shoot whether it's in-studio, on-location, or fully remote.

1. Use the Right Mic for the Right Setting

There’s no such thing as a one-size-fits-all mic. Lavalier? Shotgun? Boom? It all depends on the environment, the subject’s movement, and how close you can get to the action.

Pro tip

Don’t rely on the camera’s onboard mic for anything but scratch audio. Always bring at least one external mic and monitor every take.

Here’s how we choose:

  • Lavalier mics for sit-down interviews, hidden and clipped close to the chest
  • Shotgun mics for directional pickup in controlled environments
  • Boom mics for multi-subject setups or when you want invisible sound capture
  • Dual-system recording when we want the cleanest possible audio with room to adjust in post

Not sure what mic setup you need? We tailor the gear to the location and the story. Talk to 3Motion about your next interview shoot.

2. Control the Environment, Not Just the Gear

The best mic in the world can’t fix a bad room. Echo, HVAC noise, traffic, and even creaky floors will show up in your audio if you don’t prep the space.

Pro tip

Soft surfaces absorb sound. Hard surfaces reflect it. If you’re stuck in a glass conference room, bring extra sound blankets or shoot somewhere else.

Our go-to audio prep checklist:

  • Choose carpeted or soft-furnished rooms when possible
  • Turn off AC units, fans, and buzzing lights
  • Avoid large open spaces or echo chambers
  • Place rugs or blankets to dampen sound when needed

We scout locations for light and sound, because both matter. Let’s make sure your story sounds as good as it looks.

3. Monitor Your Audio Like You Monitor Your Framing

You wouldn’t shoot without checking your frame. Don’t record audio without monitoring it live.

Level meters aren’t enough. You need headphones on. Always. A clean waveform means nothing if there’s a buzz, pop, or reverb buried in the background.

Pro tip

Use closed-back, over-ear headphones (not earbuds) and listen as if you’re your own editor. Because you are.

What we listen for:

  • Background hums or interference
  • Peaking or distortion when subjects speak louder
  • Clothing rustle on lavs
  • Sync issues between mic and camera

Want to skip the guesswork? We bring pro monitoring, backup audio, and clean levels every time. Get in touch with the 3Motion team.

4. Record a Backup and a Backup for Your Backup

Audio is fragile. That’s why we always record redundantly.

Whether it’s an external recorder, onboard camera audio, or dual-lav setup, having a second source gives you peace of mind and options in post.

Pro tip

Set your backup mic to record at a slightly lower gain. If your main audio peaks, your safety track saves the take.

Our standard backup strategy:

  • Record to both camera and external audio recorder
  • Use a lav + shotgun combo where possible
  • Split left/right channels if two mics are in use
  • Label everything clearly in post to avoid confusion

Want full confidence on interview day? We build in fail-safes so no moment, quote, or answer gets lost. Book your interview shoot with 3Motion.

Final Thoughts: Professional Sound is a Non-Negotiable

Good audio isn’t a bonus. It’s baseline. 

In interviews, clear sound communicates trust, professionalism, and attention to detail. It keeps your audience focused on the message, not the distraction of poor production.

Pro tip

Never assume you can “fix it in post.” Capture it clean at the source, and your editor will thank you (and your audience won’t notice a thing, which is the goal).

Whether we’re miking a C-suite executive in a downtown office or a customer testimonial in a busy café, we show up with the tools, training, and attention to detail to make every word count.
