Mic test: check your microphone online, with playback
Test your MacBook microphone or any mic in seconds. Watch the live level, record a few seconds and play them back to hear what others hear, or listen to yourself live with headphones. Nothing is uploaded.
Runs entirely in your browser. Nothing is recorded, uploaded or stored.
Reading the result
- The bar jumps when you speak: the microphone works. Problems in one app are about that app's permission or input setting.
- The bar stays flat: check System Settings, Sound, Input, and raise the input volume. Make sure the right microphone is selected.
- It sounds muffled on playback: a case, sticker or dust may cover the microphone holes. On MacBooks they sit near the keyboard or along the edge.
- Peak always near the top: the input is too loud and will distort. Lower the input volume.
The test turns off echo cancellation and noise suppression, so you hear the raw microphone. Video apps add those filters on top.
Questions
How do I test my microphone?
Click Start microphone, allow access, and speak. The level bar should jump when you talk. Record a few seconds and play them back to hear exactly what others hear.
Why is my MacBook microphone not working?
Check System Settings, Privacy & Security, Microphone, and switch on the app. Then check System Settings, Sound, Input, and pick the right microphone with the input level up. If the bar stays flat everywhere, the microphone may be faulty or blocked by dust or a case.
Can I hear myself in the mic test?
Yes. Turn on Hear myself to send the microphone to your speakers live. Use headphones, or you'll get a loud feedback whistle.
Is my voice recorded or uploaded?
No. The test recording stays in your browser's memory and disappears when you leave the page.
