What the test will show
Compare a few seconds of silence with normal speech. Inspect digital background levels, speech levels and signs of clipping.
How to take the test
- Allow access to the microphone only.
- Be silent at first, then speak when prompted.
- Listen to the recording and repeat after changing one setting.
How to understand the result
These are relative digital levels, not calibrated room noise decibels. Amplification and noise reduction change the results.
Compare multiple runs under the same conditions. Then change one factor: connection, device, or setting. If the symptom persists, repeat the test on another device and save the conditions - this will help to more accurately describe the problem to support.
