What happens during the check
- Camera. MeetBench asks for HD video and measures the resolution, frames per second and brightness. It also notices strong light behind you and a black picture, for example when the privacy shutter is closed.
- Microphone. First it listens to 2–3 seconds of silence to measure background noise, then you say a phrase for 5 seconds. It measures your voice level, how far it stands above the noise, and clipping. Noise suppression and auto gain are switched off for this, so you hear the raw truth.
- Echo. Three short tones play through the speakers while the microphone listens. If it hears them, the other people in a call will hear themselves.
- Headphones. A melody plays in one channel at a time, in random order, and you say whether you heard it on the left, right or both. You can skip this step.
- Network, in parallel: ping and jitter, a short download and upload, latency while uploading, and whether UDP traffic, which calls prefer, gets through.
How to run the check
- Open MeetBench on the device and in the browser you will use for the call, ideally in the same room.
- Put on the headset you plan to use and press Start the check.
- Allow the camera and microphone. MeetBench analyses them in the browser and switches them off when it is done.
- Follow the prompts: stay quiet, then read the phrase, then answer the headphones question.
- Read the verdict. Each problem comes with a specific tip. Fix it and press Check again for that group only, or pick another camera or microphone from the list to test it.
What counts as good
| Check | Good | Problem |
|---|---|---|
| Resolution | 720p or more | below 720p is a note |
| Frame rate | 23 fps or more | below 14 fps |
| Brightness | 75–205 out of 255 | too dark or too bright |
| Background noise | −50 dBFS or quieter | louder than −36 dBFS |
| Voice | −38 dBFS or louder, 8 dB above the noise | too quiet to be heard clearly |
| Clipping | 3% of the time or less | more often: the voice distorts |
| Echo | under 12 dB | the microphone hears the speakers |
| Ping / jitter | ≤ 100 ms / ≤ 20 ms | > 200 ms / > 40 ms |
| Upload / download | ≥ 1.5 / ≥ 3 Mbps | < 0.6 / < 1 Mbps |
| Latency while uploading | grows by ≤ 100 ms | grows by more than 300 ms |
The overall verdict is the worst single result: one problem makes it “not ready”, and any note makes it “ready, with notes”.
How to fix common problems
- Dark or grainy video: face a window or a lamp; do not sit with a window behind you. Low frame rate in a dim room is usually the camera lengthening exposure.
- Background noise: close the window, move away from fans and laptops with loud coolers, or use a headset microphone close to your mouth.
- Voice too quiet: move closer, raise the input level in the system sound settings, or pick the right microphone in the list.
- Echo: use headphones, or lower the speaker volume and move the laptop away from walls.
- Network lag: move closer to the router or use a cable, stop downloads and cloud sync, and turn off the VPN if your company allows it.
- UDP blocked: calls will still work over TCP but are more sensitive to lag. This often happens on corporate and hotel networks; ask the network administrator.
Privacy and the report
Video and sound are analysed inside your browser and never recorded or sent anywhere. Network tests go to Cloudflare’s speed test servers, and the UDP check asks Google’s public STUN server for your address. Copy report gives a plain-text summary for tech support, and a link contains the measurements, browser and system, and the names of your camera, microphone and audio output, without any image, sound or IP address.
Frequently asked questions
Does MeetBench work for Zoom, Teams and Google Meet?
Yes. It checks the device, browser and network that every call service relies on. Desktop apps use the same camera, microphone and network, so the result applies to them too.
Why does the camera or microphone not appear?
Another app may be using it, or the browser or system has no permission. Close other call apps, then allow the camera and microphone in the browser’s site settings and in the system privacy settings.
Is my video recorded?
No. MeetBench reads the brightness and timing of frames and the level of the sound, in memory, and turns the devices off at the end.
How much data does the network test use?
Up to about 60 MB of download and 30 MB of upload, less on slower connections.
Can I send the result to IT support?
Yes: copy the text report, email it, or send a link that opens the same result read-only.
