A mic test with playback records a short clip and plays it straight back, so you hear exactly what others hear from your microphone. Press Record, speak normally, then Stop. The clip plays automatically and you can download it as a WAV file. The recording is made and kept in your browser; it is never uploaded.
What to listen for
- Distance: a hollow, roomy sound means you are too far away or the room is echoey.
- Hiss or hum: background noise, a cheap USB port or an earthing problem. Try another port.
- Crackle on loud words: clipping. Lower the input volume.
- Robotic or watery sound with processing on: noise suppression working too hard. Compare with processing off.
Processing on vs off
Recording with processing on is closest to what Zoom, Teams, Meet or Discord send. Recording with it off gives the raw microphone. Make one of each and compare: if the raw recording is clean, the processing is only adding artefacts and you can turn it down in your calling app.
For numbers rather than listening, use the mic test.
Common questions
How do I hear my mic playback?
Press Record, speak, then press Stop. The recording plays straight away.
Where is my recording saved?
Only in your browser's memory until you close the page. Press Download WAV to keep a copy on your device.
Why does my voice sound different on playback?
Everyone's recorded voice sounds odd to them, because you normally hear yourself partly through your own skull. Listen for noise and clipping rather than tone.
