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.
We develop secure online tools that are cloud-based or that execute locally on your device. Protecting your privacy is one of our main concerns when developing our tools.
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. All the work is done locally by the browser itself, making these tools very fast and 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.
We work hard to make our tools run locally on your device since avoiding sending data over the internet is more secure. Sometimes however this is not optimal or possible for tools which for example require high processing power, display maps aware of your current location, or allow you to share data.
Our cloud-based online tools use HTTPS to encrypt your data sent to and downloaded from our cloud infrastructure, and only you have access to your data (unless you have chosen to share it). This makes our cloud-based tools very secure.
The sample rate indicates how many audio samples are taken each second. Typical values are 44,100 (CD audio), 48,000 (digital audio), 96,000 (audio mastering and post-production) and 192,000 (high-resolution audio).
The sample size indicates how many bits are used to represent each audio sample. Typical values are 16 bits (CD audio and others), 8 bits (reduced bandwidth) and 24 bits (high-resolution audio).
Latency is an estimation of the delay between the moment the audio signal reaching the microphone and the moment the audio signal is ready to be used by the capturing device. For example, the time it takes to convert analog audio to digital audio contributes to the latency.
Echo cancellation is a microphone feature that attempts to limit the echo or reverb effect when the audio captured by the microphone is played back in speakers and then, as a result, captured once more by the microphone, in an infinite loop.
Noise suppression is a microphone feature that removes background noise from the audio.
Automatic gain is a microphone feature that automatically manages the volume of audio input to keep a steady volume level.
