Your microphone check, explained

Test your mic, listen, then choose the next step

Use the mic test above to check the sound reaching your browser. Watch the waveform, select the intended microphone and record a short sample. A moving meter confirms that audio is arriving; playback helps you judge whether your voice is clear enough for your call or recording.

How to test your microphone

  1. Start and select your inputClick Start Test and allow microphone access. Use the Microphone dropdown to choose your headset, laptop mic, USB mic or audio interface.
  2. Include silence and speechPause briefly, then speak normally from your usual position. Check that the waveform follows your voice rather than a different microphone across the room.
  3. Record and listenRecord a few sentences, finish the recording and play it through headphones. Listen for missing words, low volume, noise, room echo and distortion.
  4. Change one thing and repeatAdjust position, input gain or a relevant setting, then record again. Download samples if useful. Click Stop when finished and check the same input in your actual app.

Using Hear Yourself? Wear headphones and start with a comfortable playback volume. Speaker output can return to the microphone and create echo or feedback. Browser monitoring can also introduce delay.

Understand your mic test results

Judge the readings alongside a recording. A quiet room, a loud voice and automatic processing can all change the result; a grade alone cannot tell you how natural your voice sounds.

ReadingWhat it tells youWhat to do next
Waveform and input levelAudio is reaching the selected browser input. Movement alone does not prove speech is intelligible.Speak, pause and confirm that the response follows your voice.
Peak level and clippingPeaks show the louder parts of the digital signal. Clipping warnings suggest possible overload.Try louder speech too. Reduce gain if peaks overload; listen again for distortion.
Estimated noise floorAn estimate of quieter captured audio, affected by room noise, gain and processing.Compare silence with speech under the same settings. A lower number alone is not a better microphone.
Sample rate, channels and processingInformation the browser exposes about its capture path. Some fields may be unavailable.Check the intended input and app settings; these values do not certify hardware quality.
A–F quality scoreA summary of selected signal checks, rather than a professional equipment rating.Use it to investigate levels or noise, then listen for clarity, echo and missing words.

The level readings describe a digital signal, not calibrated room loudness in dB SPL. For methods and limitations, read how online microphone tests work.

What problem are you hearing?

Choose the symptom closest to your result. Each guide explains what to check and how to interpret the outcome.

Microphone guides for your app and device

A browser test checks this capture path. Meeting, chat and recording software can select another input or apply different processing. Use the relevant guide when the problem occurs in one place.

Privacy and the limits of a browser mic test

The tool processes test audio and optional recordings locally in your browser; it does not upload that media to TestMic.net servers. Downloaded files stay on your device until you remove them. Ordinary hosting, analytics and advertising data are separate from your test audio; see the Privacy Policy.

The test cannot certify your microphone’s frequency response, measure calibrated sound pressure or reproduce every app’s processing. A successful result here does not guarantee that another participant can hear you. Confirm the selected microphone and playback in the app you plan to use.

Microphone test FAQs

How do I know which microphone is being tested?

Choose a named input from the Microphone dropdown. Speak near that device and check the response. Device names may remain limited until permission is granted; compare another input if you are unsure.

Why does the meter move but playback has no sound?

Capture and playback use different paths. Check the recording player, output volume and selected speakers or headphones. A silent player does not, by itself, prove that your microphone failed.

Can I use the mic test on iPhone or Android?

A supported mobile browser can request microphone access, but recording formats, monitoring and device information vary. Allow access, keep the page active and use playback to confirm the result.

Does a good score mean my microphone sounds professional?

No. The score summarizes selected signal checks. It cannot fully judge pronunciation, tone, room echo, processing artifacts or suitability for a particular recording. Listen to a sample and check the destination app.

Why does my mic work here but not in Zoom, Meet or Discord?

The app may use another input or have different mute, permission or processing settings. A successful browser recording helps narrow the investigation; use the app-specific guides above for the next checks.

Getting ready for a video call?

Check the picture as well as the sound. Use the webcam test to review camera access, framing, lighting and browser video before opening your meeting app.
