The Basics of Great Audio for Live Streaming and Live Events: What You Need to Know
When planning a livestream or live event, most people focus on visuals—cameras, lighting, and stage design. But here’s the truth: great audio for live streaming and live events is even more important. Your audience might forgive a blurry video, but if they can’t hear clearly, they’ll disengage fast—whether they’re watching online or sitting in the front row.
Whether you’re hosting a webinar, hybrid conference, concert, or panel discussion, clear, professional audio helps your message land and keeps people tuned in. Here’s what you need to know to deliver top-notch sound for any kind of live experience.
🎤 Choosing the Right Microphone for Live Streaming and Events
The foundation of great audio is your microphone. Built-in laptop or camera mics won’t cut it—they pick up echo, ambient noise, and keyboard taps.
For livestreams and small live events, consider:
- USB microphones (e.g., Blue Yeti, Elgato Wave): Affordable and ideal for solo speakers or online events.
- XLR microphones: The gold standard for audio quality—great for in-person panels, music, or hybrid events when paired with mixers.
- Lavalier (lapel) mics: Perfect for presenters who need to move freely without sacrificing clarity. Learn more about lavalier mics here.
- Headset microphones: Useful in noisy environments and ensure consistent mic positioning.
For in-person events, coordinate with your AV team about input needs and wireless frequencies to avoid interference.
🏡 Optimizing Your Room for Live Sound and Streaming
The space you’re in can enhance—or destroy—your audio quality. Echo, reverb, and background noise are common issues in both virtual and physical venues.
For streaming setups:
- Use smaller rooms with carpets, curtains, and soft surfaces.
- Eliminate background noise (fans, HVAC systems, traffic).
For live events:
- Test the room’s acoustics in advance. The Sound On Sound guide to room acoustics is a helpful resource.
- Use directional microphones and proper speaker placement to reduce feedback and echo.
- Work closely with your AV team to optimize sound for both live and online audiences.
🔈 Choosing the Right PA System (Including Foldback Monitors)
When you’re planning a live event—whether it’s a conference, concert, or hybrid panel—your PA (public address) system is the backbone of your sound. It’s not just about volume; it’s about clarity, coverage, and making sure everyone hears the message—on stage and off.
Key things to consider when choosing a PA system:
- Room size and layout: A small conference room might only need a pair of powered speakers, while larger venues require distributed systems or line arrays.
- Audience size: More people means more power and better directional control.
- Type of content: Speech-only events and music performances have different requirements.
If your PA is too small, audio can be weak or distorted. Too large or improperly tuned, and it can overwhelm the space with feedback or echo. For a great overview of PA systems, check out this guide by Andertons.
Don’t forget foldback (monitors) for presenters and performers:
While it’s easy to focus on audience experience, stage monitoring is essential for presenters and performers. If they can’t hear themselves or each other, delivery suffers.
Options include:
- Floor wedges (traditional stage monitors)
- In-ear monitors (IEMs) for clear, personal monitoring
- Side fills or flown monitors for large stages or uneven coverage
Always test and EQ monitors separately from the main system to avoid feedback issues.

🎚️ Setting Proper Audio Levels
Audio levels that are too high distort; too low, and your audience can’t hear you. Aim to keep levels between -12 dB and -6 dB, both in live event mixers and streaming software like OBS Studio or Zoom.
Use headphones or in-ear monitors to check what your audience hears. Also verify audio-video sync regularly during livestreams.
⚙️ Basic Audio Processing Tips
For both online and in-person events, light audio processing can improve your sound significantly:
- Noise gate: Eliminates low-level background noise when no one is speaking.
- Compression: Balances volume levels so you’re not too loud or too soft.
- EQ (equalization): Cuts harsh or muddy frequencies and enhances clarity.
Streaming software and live mixers often include these tools. Use them conservatively and always test changes.
✅ Testing Your Audio Setup
Before going live or starting your event, test your entire audio chain. That includes microphones, audio interfaces, mixers, wireless systems, and streaming platforms. Look for:
- Buzzing or distortion
- Dead batteries or wireless interference
- Audio-video sync issues
- Room-level clarity (especially for hybrid events)
Even a quick rehearsal or soundcheck can catch problems before they reach your audience.
Final Thoughts on Audio for Live Streaming and Live Events
Whether online or in person, audio is your connection to the audience. A great message can fall flat if the sound is unclear or inconsistent. By investing in the right equipment, optimizing your space, choosing the right PA system, monitoring levels, and doing thorough tests, you’ll deliver great audio for live streaming and live events every single time.
In short: good audio isn’t optional—it’s essential.
