# How can I test my microphone?

On this page, please speak loudly and clearly to check if your microphone is  recording. If so, the volume bar should turn blue.

If not, please read our article “[My microphone is not working](http://support.interviewapp.io/invited-to-take-an-interview-start-here/my-microphone-is-not-working)“.

Once the audio setup is done, you will have to record a practice question so that you make sure that everything works fine. You will have to record an answer for at least 10 seconds. Please make sure you speak during the recording of your answer in order to be able to assess the audio quality.

If you are encountering issues with your camera, please read our article “[I can’t see myself on screen](http://support.interviewapp.io/faqs-and-troubleshooting/i-cant-see-myself-on-the-screen)“.
