What Is an Online Microphone Test?
An online microphone test checks whether your browser receives audio from your microphone. Our mic tester shows a live level meter and peak value, with an optional sample recording of up to 30 seconds so you can hear your own voice.
This is useful before meetings, classes, interviews, streams, or support calls. If the meter moves when you speak, your microphone is working at the browser level. The live meter doubles as a loudness check: watch the peak level while speaking at normal call volume. For a full setup check, also test your headphones or speakers.
What This Microphone Tester Can Verify
Whether the browser can access your microphone
Whether live input levels respond when you speak
The highest relative input level reached during the test
Whether the mic appears completely silent in the browser
How a short sample sounds when you choose to record and play it
The percentage meter is a relative signal indicator, not calibrated decibels or an automatic quality score. Listening to a sample can help you notice background noise or distortion. Your call app may process audio differently, so check its own microphone settings too.
How to Test Your Microphone Online
Click Start mic. This starts the level check only, not a recording.
Allow microphone permission in the browser prompt.
Speak at your normal volume and watch the meter move.
Check the peak value to see how loud your voice reached.
Optionally click Record sample, speak, then click Stop recording. Recording and microphone access stop automatically after 30 seconds or when you switch tabs.
After the microphone stops, press Play in the audio player to hear yourself. Playback never starts automatically.
Delete the sample when finished. To record again, start the mic and choose Record sample; a new recording replaces the previous one.
Audio stays temporarily in this tab and is never uploaded or saved to persistent browser storage. Deleting the sample, replacing it with a new recording, or leaving the page clears it. If recording is unsupported, you can still use the live meter.
Why the Meter May Not Move
Microphone permission was denied in the browser
The mic is muted physically or in the system settings
Another app is already controlling the microphone
The wrong device is active at the operating system level
The microphone or cable is not connected properly
If your webcam and mic are both involved in a call setup, check the webcam tester too. And if the meter moves while you are silent because a game or video is playing, Windows may be routing system sound into your input device — see the fix for a mic picking up desktop audio on Windows 11.
Microphone Test FAQ
How do I know if my microphone is working?
If the meter moves when you speak and the peak value increases, the browser is receiving audio input from your microphone.
Does this microphone test record my voice?
Start mic does not record. Only Record sample starts a recording, for up to 30 seconds. The sample stays temporarily in this tab and is never uploaded. Delete it, replace it with a new recording, or leave the page to clear it.
Why is my microphone not working in the browser?
Check browser permission, confirm the mic is not muted, and verify that your system is using the correct input device.
How can I hear myself in this microphone test?
Start the mic, click Record sample, speak, and stop recording. Once the microphone has stopped, press Play in the audio player. There is no live audio monitoring or automatic playback.
Does the percentage measure decibels or microphone quality?
No. Current level and peak show relative signal activity, not calibrated decibels or a quality score. Listen for noise or distortion, then check your call app because its audio processing may differ.
When does recording stop, and why might it be unavailable?
Recording stops when you stop recording or stop the mic, after 30 seconds, when you switch tabs, or if the microphone disconnects. If your browser cannot record samples, the live level meter remains available.
Analyse high-pitched PC noise with your microphone. Compare a quiet baseline with normal PC activity and inspect frequency, tonal prominence and a live spectrum.
Check audio and video sync with a moving marker and quiet beep. Adjust sound timing to compare speakers, Bluetooth headphones and displays without a download.
