Live level and waveform
A level bar shows how loud your voice is in dBFS, with a marker that holds the recent peak, and a waveform draws the signal as you speak. You can see at once whether the microphone is picking you up.
Five-second sound check
Record five seconds of speech and play it back in the page. You hear what the other side of a call will hear, including background noise, echo and a voice that is too quiet or distorted.
Pick the device and processing
Choose between your built-in microphone, a headset or a USB microphone, and switch echo cancellation, noise suppression and automatic gain on or off to hear the difference each one makes.
How to test your microphone before a call
- 1
Select Start mic test and allow microphone access in the browser prompt.
- 2
Choose the microphone you plan to use, then speak normally and watch the level bar and waveform.
- 3
Select Record 5-second sound check, say a few sentences and play the recording back.
- 4
Adjust your distance or input volume until your voice is clear and the bar stays out of the red.
What people use this tool for
- Check a headset or USB microphone a few minutes before an interview, class or client call.
- Find out whether a silent microphone is a hardware fault, a mute switch or a permission setting.
- Compare your laptop microphone with an external one by recording a sound check on each.
- Confirm that a new microphone is detected and set a sensible input volume before streaming or recording.
Frequently Asked Questions
How do I test my microphone online?
Select Start mic test and allow microphone access when your browser asks. Speak at your normal volume. The level bar and waveform should move as you talk, and the message under them tells you whether sound was detected, is too quiet or is clipping.
The bar does not move. What should I check?
First check the Microphone list and choose the device you are actually speaking into. Then look for a mute button on the headset or keyboard, raise the input volume in your system sound settings, and make sure another app has not taken exclusive control of the microphone. On Windows and macOS, the browser also needs microphone permission in the system privacy settings.
Why does my browser say microphone access was blocked?
The site was denied permission at some point, or your system blocks the browser from using the microphone. Select the lock or settings icon next to the address bar, set Microphone to Allow, and reload the page. If that option is missing, allow your browser under the microphone section of your system privacy settings.
What level should I aim for?
For speech, peaks between about −18 and −6 dBFS are comfortable: clearly above the background noise and with room to spare before distortion. If the loudest peaks stay below −30 dBFS you will sound quiet, and peaks that hit 0 dBFS are clipping, which sounds harsh and cannot be fixed afterwards.
What do echo cancellation, noise suppression and automatic gain do?
They are processing steps your browser applies before any website or call app receives the audio. Echo cancellation removes your speakers' sound from the microphone, noise suppression reduces steady background noise such as fans, and automatic gain evens out loud and quiet speech. Call apps normally leave all three on. Turn them off to check the raw signal from a studio or USB microphone.
Is my voice recorded or uploaded?
No. The level and waveform are measured in your browser and never leave it. The sound check is held in the page's memory only so you can play it back; it is replaced when you record another one and discarded when you stop, close or leave the page. The microphone is switched off when the tab is hidden.
The test works here, but my call app still cannot hear me. Why?
This test proves the microphone and the browser work. A call app has its own microphone setting and its own permission, so open its audio settings and select the same device that worked here. Desktop apps such as Zoom or Teams also need microphone permission in your system privacy settings, separately from the browser.
Does it work on phones and tablets?
Yes, in current versions of Chrome, Safari, Firefox and Edge on Android, iPhone and iPad. Phones usually offer fewer devices to choose from, and some browsers do not report which processing is in use, in which case the readout shows Not reported.
