Microphone faults are hardware events your browser receives directly through the Web Audio API, which is why only a real mic tester can give you a diagnosis. If your voice keeps cutting out in meetings, sounds thin on recordings, or never registers in games, a chatbot can only offer generic advice about drivers and system settings. This tool reads the live audio stream from your physical microphone, measures your real input level, detects clipping and background noise, plays your own voice back to you, and gives a deterministic pass/fail answer plus an exportable report you can hand to support or a store. #### Live dB Meter RMS and peak levels with green, yellow and red zones for healthy voice input #### Clipping & Noise Detection Flags distorted peaks at 0 dB and measures the noise floor of your room #### Waveform & Spectrum See the raw shape and frequency content of your voice in real time #### Exportable Report Copy, TXT, CSV or JSON output with a verdict for support and warranty ### How the Microphone Test Works The most common causes are the wrong input device selected, the mic muted or set to zero volume in the operating system, and another application holding the microphone open. Pick the correct device from the list on this page, check your system sound settings, and close other apps such as Zoom or Discord before retesting. The meter zones make this obvious. Normal speech should peak in the green zone, around -12 dB to -6 dB. If the meter barely moves above -30 dB, you will sound quiet to other people. If it regularly hits the red zone or shows clipping, your audio will distort and you should lower the input gain. Yes. The device picker lists every input the browser can see, including built-in mics, USB headsets, and Bluetooth microphones. Choose the one you actually use, then speak. Bluetooth mics sometimes report a higher latency and lower sample rate; that is normal and appears in the device information panel. An echo usually comes from speakers feeding back into the microphone, or from a listen-to-this-device option enabled in your operating system. Wearing headphones during calls removes the feedback loop, and disabling listen-back in the system sound settings removes the artificial echo. A clean setup shows a noise floor below roughly -45 dB when the room is silent. If the meter sits above -30 dB even in silence, something is adding noise, such as electrical hum, a fan, or another device near the mic. The tool records this number so you can compare setups or document a faulty unit. No. All processing happens inside your browser using the Web Audio API. Nothing is uploaded or stored. The echo test records a short clip in your own browser memory so you can play it back; closing the tab erases it completely. The device list refreshes when you click the refresh icon next to it. Plug in the new microphone, refresh the list, and it should appear. If it does not show up, check that the operating system detects the device first, then reload this page. The tool reads your microphone input to measure it, and the browser requires your permission before any website can access a microphone. Nothing can be measured without that permission. You can deny it at any time, and no part of this page works differently if you do. - **Click Start and allow microphone access.** The tool opens a real-time audio stream from your input device using the browser's getUserMedia and Web Audio APIs. - **As you speak, watch the live meter.** The meter shows your RMS level and peak level in decibels: green is a healthy voice level, yellow is loud, and red means clipping. - **Check the waveform and spectrum panels.** They show the raw shape and frequency content of your voice, which helps you spot hum, hiss, or missing high frequencies. - **Stay quiet for a few seconds** to capture your noise floor, then speak normally, softly, and loudly to check sensitivity and clipping. - **Run the echo test** to record a short clip and hear how you actually sound to other people, then review the diagnosis and export the report. ## Related Tools - [Webcam & Mic Test](/tools/webcam-test/) - Test your camera, microphone and speakers in one place - [Voice Recorder](/tools/voice-recorder/) - Record and save your voice as MP3 or WAV - [Keyboard Tester](/tools/keyboard-tester/) - Check every key, stuck keys, ghosting and rollover - [Mouse Tester](/tools/mouse-tester/) - Test every button, double-click chatter and scroll - [Audio to Text](/tools/audio-to-text/) - Convert speech to text with live voice recognition ## References - [MDN — Canvas API](https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API) - [MDN — HTMLMediaElement](https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement)
