Microphone Test

Microphone Test

Use this online tool to test your microphone and find solutions to fix it.

By using this tool, you agree with our Terms of Service and Privacy Policy.

Introduction to the Microphone Test online tool

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.

Privacy Protected

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.

Eco-friendly

The infrastructures that support the internet and the cloud have an impact on the environment. The cloud is in fact a multitude of servers powered by electricity and the production of this electricity leads to varying degrees to carbon dioxide emissions. We implement the following strategies in order to make sure that our tools have the lowest possible impact on the environment.

We work to reduce the amount of data sent to and downloaded from the internet. Whenever possible, we develop our online tools so that they execute locally on your device without the need to send large amounts of data.

We store as little data as possible (and for the shortest required time) on our cloud storage infrastructure.

Our servers are scaled on-demand, so they never use more power than needed.

Last but not least we carefully select the locations of our cloud infrastructures so that a maximum of the energy used is carbon free: at least 75% of the energy used to power our servers is carbon-free.

Microphone properties descriptions

Sample rate

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).

Sample size

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

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

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

Noise suppression is a microphone feature that removes background noise from the audio.

Auto gain control

Automatic gain is a microphone feature that automatically manages the volume of audio input to keep a steady volume level.
