Microphone Test
This lesson is part of Web Developer Tools · All levels
Summary
Microphone test checks to see if the microphone is working and how loud the sound is captured. Once permission is granted, the browser displays the meter level moving as you speak. This helps to detect problems such as incorrectly selected microphones, too low volume, or sound that is broken because of too much noise. All tests are usually done on the device without recording.
Key points
- The browser asks for microphone access permission before the device can work.
- The meter level indicates the strength of the incoming audio signal.
- Clipping occurs when the sound is too loud to cut the waveform.
- Choose the right input device when there are multiple microphones
- Use a quiet room and a reasonable distance for best test results
