How to Improve Video Call Audio Quality (Any Platform)

Bad video call audio costs more than you think. A 2024 study by Grammarly found that poor audio quality is the number one reason people disengage during virtual meetings, ahead of poor video quality and boring content. When people cannot hear clearly, they stop paying attention within 2-3 minutes.

The good news is that most video call audio problems are solvable with changes that cost nothing or next to nothing. This guide covers everything that affects video call audio quality, organized from highest impact to lowest, and works across Zoom, Google Meet, Microsoft Teams, Discord, and any other platform.

The Microphone Is 80% of the Problem

If you remember one thing from this guide, let it be this: audio quality on a video call is almost entirely determined by the microphone on the sending end. No amount of software processing on the receiving end can recover information that was never captured.

Microphone Distance

The single highest-impact change you can make is reducing the distance between your mouth and the microphone. Sound pressure drops by 6 dB every time you double the distance. At 50 cm from a mic, your voice might be 20 dB above the noise floor. At 10 cm, it is 34 dB above — a night-and-day difference in clarity.

Ideal distance: 15-25 cm (6-10 inches) for a desktop mic. A headset mic sits at 2-5 cm, which is why headsets always sound better than laptop mics in the same room.

Microphone Type Matters

Built-in laptop mics are omnidirectional condensers placed near the keyboard. They pick up everything: keyboard clicks, fan noise, desk vibrations, and room reflections. They are designed to be usable, not good.

USB condenser mics ($30-100) with a cardioid pickup pattern reject sound from the sides and rear, dramatically reducing room noise. The Blue Yeti, Audio-Technica AT2020 USB, and Elgato Wave 3 are all significant upgrades.

Headset mics ($20-60) sit close to your mouth and have tight pickup patterns. For calls, a decent headset beats a $200 condenser mic placed on the other side of the desk.

Recommendation for most people: A wired headset with a boom mic. It is the best cost-to-quality ratio for video calls. Wireless headsets (AirPods, Sony WH-1000XM5) are convenient but add Bluetooth codec compression (SBC/AAC) that reduces quality slightly.

Software Settings by Platform

Each platform has settings that affect audio quality. Here are the ones that matter most.

Zoom

• Noise suppression: Medium for home offices, High for noisy spaces. Avoid Low unless you are in a quiet studio.
• Automatic microphone adjustment: Turn it off. Manual gain staging gives cleaner audio.
• Original Sound: Enable this option if you need high-fidelity audio (music, voiceover demos). It disables all processing.
• Audio profile: Enable “High Fidelity Music Mode” for 48 kHz stereo at 96 kbps when audio quality is critical.

See our complete Zoom audio settings guide for details on every option.

Google Meet

• Noise cancellation: Turn it on. Meet’s ML-based noise removal is good and handles non-stationary noise (dog barks, door slams) well.
• No AGC toggle — Meet always applies automatic gain control. Proper gain staging on your mic reduces the damage AGC does.

See our Google Meet audio guide for the full optimization walkthrough.

Microsoft Teams

• Noise suppression: Auto (default) is fine for most situations. Switch to High for very noisy environments.
• Music mode: Available under ”…” > “Settings” > “Music mode.” Disables noise suppression and AGC for music and high-fidelity audio.
• Spatial audio: Teams supports spatial audio with compatible headsets. This separates voices in 3D space, making it easier to follow who is speaking in large meetings.

Discord

• Noise suppression: Discord uses Krisp’s AI model. Set sensitivity to “Automatic” for the best balance.
• Echo cancellation: Enable this if you are on speakers. Disable if you are on headphones (it adds a tiny amount of latency).
• Automatic input sensitivity: Leave this on unless you have a specific reason to set a manual threshold.
• Voice processing: Enable “Advanced Voice Activity” for better detection of when you are speaking vs. when it is ambient noise.

Room Acoustics — The Overlooked Factor

A good microphone in a bad room sounds worse than a mediocre microphone in a good room. Room reflections (echo, reverb) smear speech intelligibility. The consonants that make words understandable get buried in reflected sound.

Quick Room Improvements

1. Close the door. A closed room has 10-15 dB less ambient noise from the rest of the house.
2. Add soft surfaces. Bookshelves, curtains, rugs, and upholstered furniture absorb mid and high-frequency reflections. The difference between a bare-walled room and one with a bookshelf behind the speaker is immediately audible.
3. Avoid hard parallel surfaces. Two flat walls facing each other create flutter echo — rapid repeated reflections. Break this up with bookshelves, acoustic panels, or even hanging a thick blanket on one wall.
4. Position yourself away from walls. Sitting with your back against a hard wall means your voice bounces back into the mic from behind you. Pulling your desk 30 cm from the wall helps.

The Closet Trick

If you need good audio in a pinch, record from a closet. Clothes are excellent broadband absorbers, and a closet is a small, heavily damped space. It sounds absurd, but professional voice actors use walk-in closets as improvised vocal booths regularly.

Network Optimization

Video call audio uses codecs (Opus for most platforms) that degrade gracefully when bandwidth drops. But “gracefully” still means lower quality.

Bandwidth Requirements

Platform	Minimum for good audio	Recommended
Zoom	60 kbps up/down	150 kbps
Google Meet	50 kbps up/down	100 kbps
Teams	50 kbps up/down	100 kbps
Discord	64 kbps up/down	128 kbps

These are low numbers, but they need to be sustained without jitter. A connection averaging 10 Mbps but with 200ms jitter spikes will produce worse audio than a steady 2 Mbps connection.

Practical Network Fixes

1. Use ethernet if possible. Wi-Fi adds variable latency (jitter). A direct ethernet connection has stable, predictable latency.
2. Close bandwidth-heavy applications. A 4K YouTube stream running in another tab consumes 20-50 Mbps and can cause packet queuing delays that affect your call.
3. QoS (Quality of Service): Many routers allow you to prioritize traffic to specific applications. Prioritize your video call platform.
4. Turn off video if audio is cutting out. Video consumes 10-50x more bandwidth than audio. Disabling your camera immediately frees bandwidth for audio.

Headphones — The Echo Killer

If there is one hardware change everyone should make, it is wearing headphones during calls. Not for audio quality on your end (though that helps too), but because it eliminates acoustic echo for everyone else.

When your microphone picks up audio from your speakers, the other participants hear their own voice reflected back with a delay. This is distracting, fatiguing, and sometimes makes conversations impossible. All platforms have echo cancellation algorithms, but they are imperfect — they introduce artifacts, reduce voice quality, and occasionally fail entirely.

Headphones eliminate the problem at the source. Any headphones. Even cheap wired earbuds.

Receiving End — When Their Audio Is Bad

Sometimes your setup is fine but the other person sounds terrible. You cannot fix their microphone, but you can improve what you hear.

Volume Boost

If the speaker is too quiet, max out both the platform’s volume slider and your system volume. If that is still not enough, a browser-based volume booster can push the audio beyond 100%. Hearably amplifies browser audio up to 800% using a multi-band architecture with a look-ahead limiter, preventing the clipping distortion you get from cranking system volume past its limit.

EQ for Voice Clarity

A gentle EQ boost in the 2-5 kHz presence range makes speech more intelligible. Cut below 150 Hz to remove rumble and hum. This is a standard voice clarity curve used in broadcasting and hearing aid fitting.

Noise Gate

If the other person has constant background noise, some browser extensions offer noise reduction on the receiving end. This processes the incoming audio through a spectral subtraction or neural network filter before it reaches your ears.

The 5-Minute Setup Checklist

Before your next important call:

1. Headphones on (any headphones, wired preferred)
2. Mic within 25 cm of your mouth
3. Close the door and minimize ambient noise
4. Close unnecessary tabs and downloads
5. Test audio — every platform has a test feature in settings
6. Check mic selection — make sure the right input device is active
7. Check speaker selection — make sure audio outputs to your headphones

These seven steps take under five minutes and address the root causes of 90% of video call audio problems. The remaining 10% come from the other participants’ setups — and the best thing you can do about that is share this guide with them.
