Microphone Test
Press "Start microphone" and allow access to see the level meter and waveform. Use "Record 5 s and play back" to hear how you sound.
Turn these on to match typical call apps, or off to hear the raw microphone.
How to use
- Press "Start microphone" and choose "Allow"
- Speak and watch the meter and waveform move
- Use "Record 5 s and play back" to check loudness, muffling and noise
If it does not work
- Meter not moving: pick the right device in "Microphone" and check the headset mute switch
- Windows: Settings → System → Sound → Input, check the device and input volume
- Mac: System Settings → Privacy & Security → Microphone, turn on your browser
- Clipping: move away from the mic or lower the input volume in the OS
FAQ
Is my recording saved anywhere?
No. It exists only in browser memory and disappears when you close the page.
What is dBFS?
Loudness relative to the digital maximum, which is 0 dB. Closer to 0 is louder; reaching 0 means clipping. Normal speech is around -30 to -10 dB.
Can I hear myself live?
To avoid feedback howl, this page records and plays back instead of live monitoring.
