Why It Matters
A Microphone Test That Checks Everything
One free tool to check input level, frequency response, background noise, and recording quality — built for phones, laptops, and headsets.
Live Waveform Display
A real-time oscilloscope view of your voice shows whether the signal is clean, choppy, or dropping out as you speak.
Frequency Spectrum Analyzer
See your microphone's frequency response across bass, mid, and treble bands to spot gaps or rolled-off ranges.
Background Noise Test
Measure your noise floor while staying silent to catch hiss, hum, or interference before a call or recording session.
Record & Playback
Record a short test clip and play it back immediately to listen for distortion, muffling, or echo.

Troubleshooting
Common Microphone Problems This Test Reveals
If a check fails above, here's what it usually means.
Microphone Access Denied
Usually a browser permission was blocked. Check your site settings and allow microphone access, then reload this mic test page.
No Signal Detected
The meter staying flat usually means the wrong input device is selected, the mic is muted at the OS level, or a cable is loose.
Level Too Quiet
A consistently low meter reading often means input gain is turned down in your system sound settings, or you're too far from the mic.
Constant Clipping
If the clipping badge keeps triggering, your input gain is too high — lower it in your OS audio settings to avoid distorted recordings.
High Background Noise
A high noise floor while silent can point to electrical interference, a faulty cable, or a fan or AC unit too close to the microphone.
Distorted or Muffled Playback
If your recorded clip sounds muffled or crackly on playback, check for a damaged mic capsule, a covered port, or a corrupted driver.
FAQ
Microphone Test — Common Questions
Everything you need to know before running a microphone test.
Open this page, allow microphone access, and speak normally. The volume meter should move with your voice and the live waveform should react instantly. If nothing moves, the microphone is not being picked up by your browser.
The level meter shows your input in real time, including a clipping warning if your voice is overdriving the input. Low levels often mean the wrong device is selected or input gain is turned down in your OS sound settings; constant clipping means the gain is too high.
The spectrum analyzer breaks your voice into frequency bands from low bass to high treble. A healthy microphone shows energy moving naturally across bands as you speak; a flat or missing range can indicate a faulty capsule or a software filter cutting frequencies.
Stay silent for a few seconds while the noise floor meter is running. A low, stable reading means a clean signal; a high or fluctuating reading while silent points to electrical interference, a faulty cable, or aggressive noise from a fan or AC unit near the mic.
Yes. The Record & Playback section lets you record a short clip directly in your browser and play it back immediately, so you can listen for distortion, hiss, echo, or muffled audio before a call or recording session.
Yes. Any microphone recognized by your operating system — built-in, USB, Bluetooth, or 3.5mm headset mics — can be selected from the device dropdown and tested the same way, as long as your browser has permission to access it.
