Although the Sound Recorder app is similar to the Voice Recorder app on Windows 10, one of the biggest differences is that the app for Windows 11 doesn't include the audio trimming feature.

Actually, this app had a different name back on Windows 10, where it was called Voice Recorder, and truth be told, it was a far worse app. Everything has been refined and improved in tis Windows ...

You can use the Settings app of Windows 11/10 and record or play audio at a normal level for a microphone test and finally play the recorded sample to check if the microphone is working fine or not.
