QUICK MIC CHECK
Mic Check Online
Use this quick mic check when you only need to know whether your microphone is working. Start the test, allow permission, speak normally, and confirm that the live input meter and waveform respond before joining a meeting, voice chat, class, or recording session.
Allow microphone?
Use the selected microphone on this site.
Best for: confirming the microphone is detected and not muted.
Time needed: under one minute if browser permission is already allowed.
Next step: use playback or loopback if the meter moves but you still need to judge sound quality.
Why use the live tool on this page?
A successful mic check means the meter and waveform move when you speak. If they stay flat, check browser permission, input device selection, mute switches, and system privacy settings.

Select the right microphone
Browser permission, device labels, and system input all have to point to the same source.

Watch level and waveform
A live meter confirms that speech reaches the browser before you troubleshoot apps.
Quality
Use playback or loopback
Listen for clipping, delay, echo, Bluetooth quality drops, and wrong-device routing.
PASS OR FAIL
How to know if your mic check passed
The fastest signal is movement. If the live meter and waveform react to your voice, the browser is receiving microphone input from the selected device.
Passed
The meter moves, the waveform changes, and device labels appear after permission. Your browser can capture microphone input.
Needs attention
The meter stays flat, the device list is empty, or the browser shows a permission error. Check permission and input selection first.
Quality still unknown
A mic check proves input works, but it does not fully prove sound quality. Use playback or loopback if clarity matters.
STEP BY STEP
How to check your microphone online
Run the check in the same browser and device you plan to use later. This reduces surprises when you open Zoom, Discord, Meet, Teams, or a recording tool.
1. Step
Click Start and allow microphone access in the browser prompt.
2. Step
Speak at normal call volume for a few seconds.
3. Step
Watch the live meter and waveform for movement.
4. Step
Open the input dropdown and confirm the expected microphone is selected.
5. Step
If there is no movement, switch devices, unmute, and check operating-system microphone permission.
If you previously blocked the microphone, use the lock icon in the address bar to allow access, then reload the page.
FIX PATH
What to fix when the mic check fails
A failed mic check usually comes from permission, device selection, mute, low input volume, or another app using the microphone.
Permission blocked
Allow microphone access for this site and confirm the browser itself is allowed in macOS, Windows, iOS, or Android privacy settings.
Wrong input device
Switch the dropdown from the default device to your headset, USB mic, webcam mic, or built-in microphone and test again.
Muted or low input
Check hardware mute buttons, system input gain, headset inline controls, and app-level input settings.

Mic Check Online FAQ
What does a mic check do? +
A mic check confirms that your browser can detect microphone input and that the selected device responds when you speak.
Why does the mic check show no input? +
The most common causes are blocked browser permission, the wrong input device, muted hardware, low system input volume, or another app using the microphone.
Does this mic check record or upload my voice? +
No. The live meter and waveform run locally in your browser. Audio is not uploaded.
Is a mic check enough before a meeting? +
It is enough to confirm input detection. For important calls, also run a short playback test to hear actual quality.
Why are microphone names hidden? +
Browsers often hide real device names until you allow microphone permission. Start the test once, allow access, and reopen the device list.
