How to Interpret Results
This meter is a relative, uncalibrated RMS level, not a sound pressure reading, so there is no universal “healthy” range — a level that is fine on one device is too quiet on another. Judge the shape instead: stay near zero in silence, swing well up the meter during normal speech, and never sit pinned at 100%, which means the signal is clipping.
Note: Web browser tests observe the audio signal provided by the operating system driver. They cannot detect acoustic imperfections caused by external room echo or wind.
Microphone Troubleshooting Steps
- Check if your physical microphone or headset has an in-line hardware mute switch.
- Ensure the correct default audio input device is selected in your system sound preferences.
- Close background communication apps (Zoom, Teams, Discord) that might hold exclusive device locks.
- Confirm the browser site permission is set to "Allow" in your address bar lock/tune icon.
This tester needs your permission
Your browser will ask for access the moment you start. Click “Allow” when the prompt appears — the test cannot see or send anything without it.
Allowed it but nothing happens? Click the lock (or tune) icon in your address bar and set this site's access to “Allow”, then reload. A fresh reload applies the new permission immediately.
Why we ask
Permission stays on your device: the test reads the live signal locally and nothing is recorded or uploaded.
How to Test
- •Click Start Test to grant microphone permission.
- •Speak into your microphone and observe the live relative input level and waveform.
- •Open the Pitch tab to detect musical pitch, or the Recorder tab to record and replay a 5-second sample.
Browser Limitations
- •Digital meter readings reflect browser input gain, not calibrated acoustic sound pressure (SPL).
- •Noise suppression applied by your operating system or browser may alter waveforms.
Troubleshooting Tips
- •If permission is blocked, click the lock icon in your browser address bar and allow microphone access.
- •Check that your headset or external mic is selected in the device dropdown.
Why test your microphone online?
Your microphone is the one component every video call, voice note, podcast, and online interview depends on — and it fails more often than you think. Operating system updates silently reset privacy permissions, conferencing apps grab exclusive input locks, and USB headsets lose their default-device status after a reboot. A 60-second online microphone test tells you instantly whether your voice actually reaches the computer, how strong the input level is, and whether background noise is drowning you out.
This tester captures the microphone through the same standardized browser APIs (getUserMedia and the Web Audio Analyser) that any web app relies on. That makes it a clean read of what the hardware is delivering — but not a promise about what a given app will send. Zoom, Google Meet, and Microsoft Teams each layer on their own processing: noise suppression, echo cancellation, automatic gain control, and per-app device and level settings, and they may select a different input entirely. A healthy reading here means the signal reaches the browser cleanly; how a specific call app then treats it is that app’s own behaviour. No software installation, no drivers, no account — the audio never leaves your browser, and the meter, waveform, and optional recording all run locally in memory.
How to get an accurate result
- Speak at the distance you would actually sit from the mic during a call — about 15–25 cm (6–10 inches) for a headset boom.
- Watch the meter while silent for a few seconds first, then speak normally. The gap between the two readings is your usable signal — a meter that never drops back toward zero while the room is quiet usually means aggressive gain or a noisy preamp.
- If the level barely moves when you speak, raise the input volume in your system sound settings until speech sits well up the meter without ever pinning it at 100%.
- Use headphones if you are testing near speakers — otherwise your mic picks up their output and can feed back.
- Record a short sample and play it back: the meter only shows level, whereas playback is the only way to hear distortion, crackle or hiss, room echo, and wind noise on the mic itself.
- Disable browser noise suppression temporarily if you want to judge the raw signal your mic produces.
Common microphone problems and fixes
The meter shows nothing when I speak
The wrong device may be selected. Open your system sound settings and confirm the input device matches your headset or webcam mic, then reload this page and re-allow permission.
The level is very low even when I speak loudly
Raise the microphone input level in system settings (Windows: Settings → System → Sound → Input; macOS: System Settings → Sound → Input). Also disable "automatic gain control" in your conferencing app, which can fight the browser.
Other people hear robotic or distorted audio
Distortion usually means the input level is clipping. Pull the gain down until speech peaks stop hitting the top of the meter, and close apps that may be processing audio in the background (noise removers, virtual cables, voice changers).
Microphone works here but not in Zoom/Teams
Conferencing apps can hold an exclusive lock or select a different input. Fully quit the app (check the system tray), then reopen it — or the reverse: quit the app before testing here for a clean measurement.
A constant hiss or hum is always present
Hiss at high gain is normal for cheap analog mics. A steady low rumble that never goes away is often electrical interference rather than the room — try a different USB port, move cables away from power bricks, or use the mic on another device to isolate the cause.
Allow access in your system settings
Windows 10 & 11
- Open Settings → Privacy & security → Microphone.
- Enable "Microphone access" and "Let apps access your microphone".
- Under "Let desktop apps access…", make sure your browser is allowed.
- Check Settings → System → Sound → Input to select the right device and set the input volume.
macOS
- Open System Settings → Privacy & Security → Microphone.
- Enable the toggle next to your browser (Chrome, Safari, Firefox…).
- Check System Settings → Sound → Input and select your microphone; watch the input level respond as you speak.
Linux (PulseAudio / PipeWire)
- Open your audio settings (pavucontrol or GNOME/KDE sound settings).
- On the Input Devices tab, confirm your mic is not muted and set a sensible base volume.
- On the Recording tab, verify your browser appears and receives signal while testing.
Microphone test FAQ
Is this online microphone test really free?
Yes — completely. There is no registration, no watermark, no recording limit, and no upload. The test runs entirely in your browser using standard Web APIs.
Can I test a Bluetooth headset or AirPods?
Yes. Pair them first and select them as the system input device before reloading the page. Note that most Bluetooth headsets switch to a lower-quality codec while the microphone is active — that is a headset limitation, not a browser one.
Why does the recording sound worse than the live meter?
Playback passes through your output chain (sound card, speakers/headphones), and echo cancellation or noise suppression may process the recording. Test with headphones to separate mic quality from playback quality.
How many microphones can I test?
As many as your system exposes — internal laptop mics, USB webcams with built-in mics, headset booms, and audio interfaces. Switch the system default input device and reload to test the next one.
Does the test work on iPhone and Android?
Yes. On iOS, Safari will prompt for microphone permission the first time; on Android, Chrome behaves the same as desktop. Built-in phone mics usually have aggressive noise suppression, so expect a cleaner but more processed waveform.
What is a healthy input level for voice calls?
The meter is relative, not calibrated — it shows how strong the signal is right now, not a sound pressure level, so there is no single correct number and readings are not comparable between devices. Use the shape instead: silence should rest low, normal speech should swing well up the meter, and peaks should never sit pinned at 100%, which is what clipping sounds like.
Can I compare this reading against a professional sound level meter?
No. The meter is an uncalibrated relative RMS level derived from whatever gain your operating system and input hardware are already applying. A higher number means a stronger signal at the browser, not a louder room or a better microphone.
