About this tool
A microphone test lets you confirm your mic is connected, selected and picking up sound before an important call, recording or stream. Press start, allow microphone access when your browser asks, and speak: the level meter jumps with your voice, the live waveform shows the actual signal, and the readout displays the active input device and its sample rate.
To hear exactly what others will hear, use the record button: a short clip is captured with your browser's built-in recorder and played back to you instantly. If the meter moves but the recording sounds quiet or distorted, adjust the input level in your operating system's sound settings and test again.
Your audio never leaves your device. The analysis runs locally with the Web Audio API, the recording lives only in your browser's memory until you leave the page, and this site's security policy blocks uploads to any server — nothing is transmitted, stored or shared.
Frequently asked questions
The test says access was denied — how do I fix it?
Your browser blocked the microphone for this site. Click the camera/microphone icon in the address bar (or open the browser's site settings), allow microphone access, then press start again. On macOS and Windows also check the system privacy settings allow your browser to use the mic.
Is my voice recorded or uploaded anywhere?
No. The level meter and waveform are computed locally in your browser, the optional test recording stays in memory on your device, and the site's Content Security Policy blocks any upload — your audio physically cannot leave your machine.
The meter does not move when I speak — what should I check?
Make sure the right input device is shown in the readout, the mic is not hardware-muted, and its input level is up in your system sound settings. If another app is using the mic exclusively, close it and press start again.
Why does my recording sound different from my voice?
You normally hear your voice partly through your own head, so recordings always sound a little unfamiliar. The playback is what other people actually hear on calls — use it to judge loudness, noise and clarity.
