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 online tools that are executed locally on your device. So our tools don't need to send your files or audio and video data over the internet in order to process them. All the work is done locally by the browser itself, making our tools fast and secure! Note that if you use our location or sharing tools, location data or the data you share will be sent over the internet.
Whereas most other online tools send files to remote servers in order to perform operations on them, we don't. With us, your privacy is protected!
We achieve this by using the latest web technologies: HTML5 and WebAssembly, a form of code that is run by the browser allowing our online tools to execute at near-native speed.
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.
