How to Test Your Microphone Online

1. Press Test my microphone and choose Allow when the browser asks. The checklist ticks off browser support, permission and the microphone it found.
2. Speak, sing or clap. When sound arrives the verdict turns green: Your microphone is working. The meter shows the peak and RMS level and the waveform moves with your voice.
3. Look at Input level in the checklist. It says whether the level is good, too quiet or clipping, and what to change.
4. Press Measure background noise and stay quiet for 3 seconds to see how noisy the room and the microphone are.
5. Press Record 5 seconds, then play the recording back. Download it as WAV (or WebM) if you want to compare microphones.
6. Using more than one microphone? Pick another one in the Microphone menu and the test restarts with it.

What the Mic Test Results Mean

Result	What it means	What to do
Working (green)	Sound reaches the browser from the named microphone.	Check the level: aim for RMS between −30 and −12 dBFS when you speak.
Very quiet (amber)	The microphone sends only faint noise.	Move closer, raise the input volume or choose another device.
Silent (amber)	The microphone is connected but sends digital silence.	Check a mute switch or mute key and the system input volume.
Blocked (red)	The browser or the operating system refused access.	Follow the fix shown for your browser and system, then test again.
No microphone found (red)	No input device is connected or enabled.	Plug in a microphone or headset and enable it in your sound settings.
Busy (red)	Another app holds the microphone or the driver stopped.	Close call and recording apps, reconnect the microphone.

Reading the Level Meter: dBFS, Peak, RMS and Clipping

Digital audio is measured in dBFS (decibels relative to full scale). 0 dBFS is the loudest value a recording can hold; everything else is negative. The peak is the loudest single moment, and RMS is the average power, closer to how loud the sound feels. A pure tone at full scale has a peak of 0 dBFS and an RMS of about −3 dBFS.

Reading	Good range	Why
Speaking or singing (RMS)	−30 to −12 dBFS	Loud enough to be clear, with room before clipping
Peaks	Below −3 dBFS	Leaves headroom for sudden loud sounds
Clipping	Never	At 0 dBFS the waveform is cut off and sounds harsh; the CLIP light stays on until you reset it
Background noise floor	Below −60 dBFS (very quiet), −60 to −45 (normal)	Above −45 dBFS noise will be audible in calls and recordings

The white marker on the meter holds the highest peak for 1.5 seconds. On the waveform the red lines mark 0 dBFS: if the wave touches them, the signal clips. The spectrum shows which frequencies the microphone picks up, from 50 Hz to 16 kHz, and names the loudest one, useful for spotting hum at 50 or 60 Hz. For a detailed picture over time, open the spectrogram viewer.

Background Noise, Echo Cancellation and Noise Suppression

Browsers can clean up a microphone for video calls with three switches: echo cancellation removes the sound of your speakers, noise suppression filters out steady noise like fans, and auto gain keeps your level constant. The mic test starts with all three off so you see the raw microphone. Turn each one on and the tool restarts the microphone, measures again and reports the change, for example “background −48 → −70 dBFS (22 dB quieter)”, plus whether the browser actually applied it.

For calls, noise suppression and echo cancellation help. For music and pitch tools they can cut quiet notes and smear the pitch, which is why the tools on this site switch them off. More on this in noise and background interference.

Record and Play Back: Hear How You Sound

A level meter shows that sound arrives; a recording shows how it sounds. Record 5 seconds of speech or singing and play it back through headphones. Listen for hiss, hum, a muffled or tinny tone, distortion and room echo. The WAV download is uncompressed (48,000 Hz, 16-bit), so you can compare two microphones fairly; the WebM file is compressed and much smaller.

Mic Test for Singing: Am I a Good Singer?

Before any singing test, make sure the microphone is not the problem: a quiet or clipping microphone makes every pitch tool less reliable. Use Sing a note in the mic test: hold an “ah” and it names the note, the frequency and how many cents you are off. If it reads your note steadily, the microphone is ready for singing.

• To score how in tune you sing, use the pitch accuracy checker.
• To see which note you are singing moment by moment, open the singing note detector.
• To find your lowest and highest notes, take the vocal range test.

Microphone Not Working? Quick Fixes

• Blocked: allow the site in the address bar, then check the system privacy setting (Windows: Privacy & security → Microphone; Mac: Privacy & Security → Microphone) and restart the browser.
• Silent: look for a mute switch on the headset cable, a mute key on the laptop keyboard, or an input volume set to zero.
• Wrong microphone: laptops often have a built-in microphone, a headset and virtual devices. Pick the right one in the Microphone menu.
• Bluetooth headsets switch to a low-quality call mode when the microphone is used. A wired or USB microphone sounds much better.
• Works in other apps but not here: the browser needs its own permission, and only one app may use some microphones at a time.

The troubleshooting panels inside the tool give step-by-step fixes for Chrome, Edge, Firefox, Safari, Windows, Mac, Android and iPhone. More help: troubleshooting guide.

Frequently Asked Questions

Is this microphone test private?

Yes. The sound is analysed in your browser and never uploaded. The 5-second recording stays in your browser’s memory until you close the page. See data security.

How do I know if my mic is working?

Press Test my microphone and speak. If the verdict turns green and the meter moves with your voice, the microphone works. If it stays silent, check the fixes above.

Why is my microphone so quiet?

The input volume is low, you are too far away, or the wrong device is selected. Raise the input volume in your system sound settings until your speech reaches about −20 dBFS RMS.

Can I test a USB, headset or Bluetooth microphone?

Yes. Every microphone your browser can use appears in the Microphone menu. Choose it and the test restarts with that device and shows its name, sample rate and channel count.

Does the mic test work on iPhone and Android?

Yes, in Safari and Chrome on iPhone and in Chrome, Firefox or Samsung Internet on Android. Allow the microphone when asked; iPhones usually report 48,000 Hz, mono.
