Click "Start Test" and speak into your microphone
🔒 Your audio stays entirely in your browser — nothing is recorded, uploaded, or sent anywhere.
This tool checks that your microphone is working by showing a live volume level and frequency bar visualizer as you speak — no recording involved, no download needed. Grant microphone access, speak normally, and watch the bars respond. If you have multiple microphones connected, switch between them to find the one that's actually working. A peak indicator (the white line) shows your loudest recent level, useful for checking you're not clipping or too quiet.
No. Audio is analyzed entirely within your browser in real time to show the volume meter — nothing is recorded, saved, or transmitted anywhere.
Check that your browser is using the correct microphone (use the device dropdown if you have more than one), and confirm your microphone isn't muted at the hardware or OS level.
That's your peak level — it shows the loudest recent volume and slowly decays, helping you see if your mic input is too quiet or too loud (clipping) at a glance.
