Microphone Test allows you to test your microphone directly in your browser. It also provides instructions on how to fix your microphone on many devices and with many voice and video calls applications.
There are many reasons why your microphone might not be working. You might have microphone issues if the application using the microphone doesn’t have the correct settings. Or the microphone might not function at all on your device, regardless of the application you're using.
After starting the test, speak loudly in your microphone and if it is working you’ll see colored sound waves appear and fade away. If your microphone is not working, you’ll see an error message. In that case you can check out the instructions to fix microphone issues specific to your device or application.
With our microphone test your privacy is totally protected: no audio data is sent over the internet, the voice or sounds that you record never leaves your device. Check out the “No data transfers” section below to learn more.
