About this tool
Check your microphone with a live volume level meter and playback - useful for confirming your mic is working, picking up sound at a good level, and sounds clear before joining an important call or recording session.
How to use this tool
- Allow microphone accessGrant browser permission to capture your selected mic input.
- Speak at normal volumeWatch live level meter for healthy non-clipping range.
- Record short samplePlayback test clip to evaluate noise and clarity.
- Tune input setupAdjust gain/device/position and retest until clean.
Getting clear sound from your microphone
Speak at a normal volume and watch the level meter: it should move into the middle of the range, not stay near the bottom or hit the top. Keep a headset mic two or three fingers from your mouth, and a desk mic about 15 to 30 cm away.
If you sound quiet, raise the input level in your system sound settings. Echo on calls usually comes from speakers feeding back into the mic; headphones fix it immediately.
Key features
- Avoids poor audio quality during important calls.
- Shows level issues before recording begins.
- Helps detect noise, distortion, or wrong input devices.
- Quick browser-based audio diagnostics.

Frequently asked questions
It's designed for a live test/preview of your microphone; check the specific playback feature's behavior, but the core purpose is testing, not creating a stored recording.
It visualizes how loud your microphone is picking up sound in real time - useful for checking your input level isn't too quiet (hard to hear) or so loud it's clipping/distorting.
Your browser will prompt for microphone access before the test can run - a standard permission you control directly and can revoke in your browser settings anytime.
For a headset or desk microphone, about a hand-width to 15 cm from your mouth. Too close causes popping on p and b sounds; too far picks up room echo and background noise.
Check the input level in your system sound settings, make sure the right device is selected, and move closer. Some laptops pick a built-in mic even when a headset is plugged in.
Use headphones so your speakers do not feed back into the microphone, and talk in a room with curtains, carpet or furniture rather than bare walls.
