Microphone Test
A free test page for desktop and laptop microphones. Confirms your browser has permission to capture audio, your mic is producing real signal, and a recorded sample plays back clearly. Run it before a Teams or Zoom call, on a customer-facing phone-bridge desk, or on a remote agent's workstation.
Read the Mic Test guide for help reading the verdict or fixing each failure mode.

Audio level is being captured
Speak into the microphone. The meter below shows live signal level for about 5 seconds.
Say something now. Count to five, read a sentence, or just say "test, test, test". The meter below moves with your voice. The check runs for about 5 seconds.
Peak RMS: 0.000 Average RMS: 0.000 Time left: 5.0s
Recorded sample plays back
A 3-second sample is recorded and played back. Confirm whether you hear yourself clearly.
Listen to the playback. Use your speakers or headphones (turn volume up if needed). The clip is whatever you said during the level check, recorded and played back from a local Blob URL.
Did you hear yourself clearly?
