Microphone-Test.org is a free online tool that allows you to test your mic directly from your browser. The way it works is simple. Click Start the Test above, allow access to your mic, and speak. You can see how your microphone is doing using the live meter and frequency graph, and confirm in seconds whether your mic is heard. We also have a recording functionality that'll allow you to hear the sound from your microphone. There is nothing to install and nothing to sign up for! The test runs entirely in your browser, for free, and the audio from your mic never leaves your device.
You can test your microphone in under a minute. The tool works the same on a laptop, a desktop, or a phone, and in every major browser. Follow four steps.
If the meter reacts, the browser can hear your microphone. If it stays flat, the cause is almost always a permission or the wrong input device, not broken hardware. The next section explains how to read the result.
A working microphone shows three signs at once. The volume meter rises and falls as you talk. The frequency graph paints bars across the spectrum, taller where a pitch is louder. The information panel names the exact device the browser opened, with its sample rate, channels, and processing. When the three agree, the signal is clean and the hardware is fine.
A red CLIPPING warning means the input is too loud and will distort. Lower the input volume with the slider, or move back from the mic. A meter that never moves points the other way: no signal is arriving. Confirm the right device is selected, then check the permission. The platform guides below open the exact toggle for your system.
If the meter above stays flat, the problem is usually a setting, not the hardware. These step-by-step guides open the right permission on every platform.

After the test starts, the information panel reports what the browser opened. Here is what each field tells you.
| Field | What it means |
|---|---|
| Label | The friendly device name, such as “Built-in Microphone”. |
| Device ID & Group ID | Short identifiers for the exact hardware and the group it belongs to. |
| Sample rate (Hz) | Audio samples captured per second. Higher means more fidelity. |
| Size (bit depth) | Bits per sample, which sets the dynamic range. |
| Latency (s) | Delay between input and processing. Lower is better. |
| Channels | Number of audio channels. One is mono, two is stereo. |
| Echo cancellation | Browser echo removal, shown on or off. |
| Noise suppression | Browser noise filtering, shown on or off. |
| Auto gain control | Automatic volume levelling, shown on or off. |
Open Microphone-Test.org, choose your input device, and click Start the Test. Allow access when your browser asks, then speak. The volume meter and frequency graph react instantly when the microphone works. You can also enable loopback or record a short clip to check the quality.
Yes. The microphone test is completely free. There is no account, no download, and no limit on how many times you run it.
No. The test runs entirely in your browser. Your audio is processed on your device and is never uploaded or stored. Any clip you record stays on your computer until you choose to download it.
A connected microphone that produces no signal is almost always blocked by a permission or set to the wrong input, not a hardware fault. Select the correct device in the tool, then open your system or browser microphone permission. Our platform guides cover the exact steps for Windows, macOS, Linux, Chromebook, Android, iPhone, and every major browser and calling app.
It works in all modern browsers, including Google Chrome, Mozilla Firefox, Safari, and Microsoft Edge, on both desktop and mobile. The browser only needs permission to use the microphone for this page.
Yes. Open the page in your phone browser, tap Start the Test, and allow access. The same meter and frequency graph work on Android and iPhone.
