We work hard to make our tools run locally on your device since avoiding sending data over the internet is more secure. To achieve this we use HTML5 and WebAssembly, a form of code that is run by the browser itself allowing our tools to execute at near-native speed. All the work is done locally by the browser itself, making these tools very fast and secure.

Our online tools which execute locally on your device don't need to send your data (your files, your audio or video data, etc.) over the internet. Protecting your privacy is one of our main concerns when developing our tools. We develop secure online tools that are cloud-based or that execute locally on your device. Check out the “No data transfers” section below to learn more. 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. In that case you can check out the instructions to fix microphone issues specific to your device or application.

If your microphone is not working, you’ll see an error message. Or the microphone might not function at all on your device, regardless of the application you're using.Īfter starting the test, speak loudly in your microphone and if it is working you’ll see colored sound waves appear and fade away. You might have microphone issues if the application using the microphone doesn’t have the correct settings. There are many reasons why your microphone might not be working. It also provides instructions on how to fix your microphone on many devices and with many voice and video calls applications. Microphone Test allows you to test your microphone directly in your browser. Introduction to the Microphone Test online tool
