Click Allow microphone access above, then speak. The level bar and waveform should react. Record a few seconds and play it back to hear exactly how you sound to everyone else. Nothing is uploaded; it all stays in your browser.
Microphone Test — Check Your Mic Online
Test your microphone in the browser. See a live input level and waveform, record a sample and play it back, and pick the right input device. No install.
How to use
- Allow microphone access. Click Allow microphone access and accept the browser prompt. Nothing leaves your device. The audio is processed locally.
- Watch the level and waveform. Speak normally. The input bar should move and the waveform should react. If it stays flat, the mic isn't picking you up.
- Record and play back. Hit Record a sample, talk for a few seconds, stop, and play it back to hear exactly how you sound to others.
Why test this
A microphone that sounds fine to you can be silent, muffled, or full of static to everyone else on the call. You usually find out mid-meeting. Testing it first takes seconds and saves the awkward 'you're on mute' scramble. Run it before a job interview, a stream, a podcast take, or any voice or video call on a new headset or a machine you don't normally use. It is also the fastest way to tell a hardware fault from a software one. If the level bar moves here, in the browser, your mic and drivers work and the problem is in the app or its settings. If it stays flat even after you pick the right device and unmute, the issue is the microphone or the OS permission. Because everything runs locally, you can test a work laptop without anything being recorded or uploaded.
What the results mean
Two things tell you the mic is alive: the input-level bar should jump when you speak and settle near zero in silence, and the waveform should wiggle in time with your voice. A bar that pins to the top (turns red) means your input gain is too high and you'll clip and distort. Lower it in your OS sound settings. A bar that barely moves means low gain or the wrong device. The real test is the recording: play it back and listen for clarity, background hum, or a tinny, distant sound. The sample-rate and channel readouts confirm the device negotiated a sane format. Most mics are mono at 44.1 or 48 kHz. If everything looks right here but a specific app still can't hear you, the fault is that app's microphone permission or device selection, not your hardware.
FAQ
- Is this microphone test safe, and do you store my audio?
- Nothing is uploaded or stored. The audio is captured and analysed entirely in your browser, and any recording you make lives only in this tab until you close it.
- Why does my microphone show no input?
- Check that you allowed access in the browser prompt, that the right device is selected in the picker, and that the mic isn't muted in your OS or on the hardware. Other apps holding the mic can also block it.
- Can I choose which microphone to test?
- Yes. Once access is granted and more than one input exists, an Input device dropdown appears so you can switch between your built-in mic, headset, or external interface.
- What sample rate and channels should I expect?
- Most built-in mics report 44.1 or 48 kHz and a single (mono) channel. Headsets and interfaces vary. The tool shows whatever your device and browser actually negotiate.
- Why can't I record a sample?
- Recording uses the MediaRecorder API. It works in current Chrome, Edge, Firefox and Safari; on very old browsers the level meter still works but the record button may do nothing.
