Real-time microphone input level monitoring with visual waveform display. Test microphone sensitivity, detect background noise, and verify audio input is working correctly. Essential for checking microphone before video calls or recording sessions.
Professional microphones can capture frequencies from 20Hz to 20kHz (human hearing range). This tester shows your microphone's frequency response in real-time, helping you identify if your mic is picking up unwanted background noise or if certain frequencies are being cut off.
Start with the live tester below. Supporting details, FAQs, and troubleshooting guidance are placed after the tool so the main action is easier to find and use immediately.
Check if your microphone captures sound and view live volume levels.
Common problems
If the live tester does not behave as expected, these are the first checks most users should try before assuming the hardware is broken.
Speak at normal volume - check if levels are appropriate
Test different distances - find optimal microphone distance
Check for background noise - look for unwanted signals in waveform
Test with different browsers - some browsers have better audio support

Test your keyboard input, detect dead keys, and verify all keys are working correctly.
Test mouse buttons, scroll wheel, pointer tracking, and touch input.
Test your speakers or headphones with reference tones.
Test your webcam, verify camera works, and check framing.
Helpful questions
Use these answers to understand results, browser limitations, permissions, and sensible next troubleshooting steps.
Low-level movement usually means the microphone is picking up ambient sound such as fans, keyboard noise, room echo, or automatic gain adjustment from the browser or operating system. Test once in a quiet room and once while speaking normally so you can compare background noise with your actual voice level.
Use the tool to confirm that your browser can access the microphone, then speak at the same distance and volume you plan to use during the call or recording. Watch for clipping, weak levels, or obvious background noise before you join the meeting or start recording important audio.
First verify browser permission, then confirm the correct microphone is selected in your operating system and browser settings. If you use a USB microphone, reconnect it and refresh the page. If you use a headset, make sure the input device has not switched back to the laptop's built-in microphone.
