5 Simple Ways to Improve Audio Quality in Your Sermon Videos

Clear audio is one of the most overlooked aspects of church video, but it’s also one of the most important. When viewers struggle to hear what’s being said, or are distracted by background noise, they tune out fast, no matter how good the message is. Thankfully, you don’t need a full studio to sound better online.

Whether you’re filming with a phone, camcorder, or livestream setup, these five simple strategies will help you capture clean, clear audio your congregation can actually follow. They’re budget-friendly, beginner-proof, and make a big impact.

1. Use an External Microphone

Relying on your camera’s built-in mic is the most common audio mistake churches make. Invest in a lavalier mic, shotgun mic, or USB mic, depending on your setup. Even affordable models under $100 will dramatically improve clarity.

Reduces echo and background noise
Captures the speaker’s voice directly
Works well with phones, DSLRs, or mixers

2. Get the Mic Close

The closer your mic is to the speaker, the cleaner your sound. Position a lapel mic near the chest or a boom mic just out of frame. Avoid placing mics across the room or relying on pulpit mics for video, distance creates muddiness and echo.

Improves vocal focus
Minimizes ambient sound pickup
Helps speech cut through music or background

3. Eliminate Background Noise

Turn off fans, close windows, and reduce any hums or buzzes from nearby electronics. If you’re filming in a live service, use a direct feed from your soundboard instead of relying on the room’s natural acoustics.

Reduces distractions in quiet moments
Improves post-production editing control
Makes your message easier to follow

4. Monitor Your Audio While Recording: Always plug in a pair of headphones during setup or live recording to hear what your audience will hear. This lets you catch hums, clipping, or mic issues before it’s too late. Many cameras and phones have headphone jacks or Bluetooth options, don’t skip this simple check.

5. Use Light Editing to Clean Up the Sound: Basic software like Audacity or online tools like Veed.io allow you to remove background noise, balance levels, and smooth out harsh frequencies. You don’t have to become an engineer, just trimming the highs and boosting clarity goes a long way.

Use Balanced or Shielded Cables: If you're using mixers or longer cable runs, make sure you're using high-quality balanced cables (XLR or TRS). This reduces signal interference, especially in buildings with lots of lighting or electronics. It’s a small investment that protects your audio integrity.

Echo is often caused by using distant mics or recording from the room’s sound rather than a direct audio feed. Use closer mics or run audio directly from the soundboard to solve this.
