The meter moves when you speak
The browser is receiving an active audio signal from the selected microphone. You can see the relative level rise and fall in real time with your voice.
Microphone Test
Test your microphone in your browser. Start the test, choose the input you want to check, and speak normally. The live meter shows whether sound is reaching the browser.
Ready to test your microphone?
Start the test, allow microphone access, and say a few words. See your voice on the live waveform and record a short sample to hear it back.

How to test your microphone
1
Start the test
Select Start microphone test. Your browser will ask for microphone access.
2
Speak normally
Talk at the same distance and volume you would use on a call or recording.
3
Watch the result
If the meter and waveform move with your voice, the browser is receiving audio from the selected microphone.
What the microphone test tells you
The meter barely moves
The selected microphone may be quiet, too far away, or set to a low input level in your operating system sound settings.
The meter stays flat
The browser is receiving zero signal. Check the selected input device, browser permissions, operating-system privacy controls, and physical hardware mute switches.
The signal is very strong
If the level consistently stays near 100%, reduce input volume in your operating system or move slightly further from the microphone to avoid distortion.
Microphone not working?
1
Check the selected microphone
If multiple inputs are connected, select the exact microphone you want to test from the Input device dropdown.
2
Check browser permission
Click the lock or site settings icon next to your browser address bar. Confirm that Microphone access is set to Allow.
3
Check operating-system permission
Windows, macOS, iOS, and Android independently control microphone access. Ensure your operating system privacy settings permit browsers to access audio devices.
4
Check hardware mute controls
Many headsets, USB microphones, and laptops have a physical mute button, an inline cable switch, or a flip-to-mute boom that silences the hardware.
5
Close competing apps
Calling or recording applications such as Zoom, Teams, or Discord can sometimes lock exclusive control of your microphone. Close them and restart the test.
6
Reconnect the device
For USB or Bluetooth microphones, unplug and reconnect the cable or toggle Bluetooth off and on, then restart the test.

Common questions
How do I test my microphone online?
Click Start microphone test. When your browser prompts for permission, select Allow, and speak at your normal volume. The live level meter and waveform will immediately show whether sound is reaching your browser.
Why is my microphone not showing any input?
Check that the intended microphone is selected in the Input device dropdown. Confirm that any physical mute switch on your headset or cable is turned off, and verify that both your browser and operating system have granted microphone access.
How do I choose a different microphone?
After starting the test, select your preferred device from the Input device dropdown. You can switch between built-in laptop microphones, external USB microphones, and headsets without reloading the page.
Why does the microphone level look low?
Device microphones often use conservative input gains to prevent clipping. Check your operating system's sound settings (such as Windows Sound Settings or macOS Sound Input) and increase the input volume slider.
Does DeviceTestRoom record or store my microphone audio?
No. Live audio is processed entirely inside your browser using the Web Audio API. Audio is never recorded automatically, never uploaded, and never sent to any server. If you use the optional 5-second playback feature, that sample exists solely in temporary local memory.
Can I test a headset or USB microphone?
Yes. Any audio input recognized by your operating system and browser can be tested. Once connected, select it from the Input device selector.
Does the microphone test work on phones and tablets?
Yes. It works on modern mobile browsers including Chrome on Android and Safari on iOS. Simply grant microphone permission when prompted by your mobile browser.
Why does my microphone work here but not in another application?
Successful browser detection confirms that your microphone hardware and operating-system drivers are working. If another app (such as Zoom, Teams, or Discord) cannot hear you, check that specific app's internal device settings, in-app mute status, and app-level privacy permissions.
