Microphone Test
Speak, and watch your microphone level. Nothing is recorded or uploaded.
What the test shows.
The bar shows your microphone volume in real time. You will notice whether your microphone delivers a signal at all and how loud you come across at a normal speaking volume.
How the measurement works.
Your browser reads the microphone signal through the Web Audio API and calculates the volume right on your device. No recording and no file is created. Your microphone signal never leaves the browser.
What the test cannot do.
This test does not replace Diktat's own permission check. On macOS you still need to allow microphone access for your browser once, in System Settings, independent of this page.
Step by step.
- Allow your browser to access the microphone.
- Pick your input device from the list, if you have more than one.
- Speak at a normal volume.
- Read the level on the bar and stop the test.
