Hello Jan,
I have found your Silence Detector app extremely useful for quite a few years. I have been using the app for both silence detection and audio volume calibration.
I have been using my quite old Dell D610 laptop running Windows XP, streaming different online radio stations unattended via a micro transmitter in my house to a couple of radios. Since the various streaming radio stations have very different audio volumes, the calibration feature is essential.
I recently purchased a somewhat old Dell E6420, and I am testing your Silence Detector for calibration under Windows 7. Again, your app is working perfectly.
Eventually, I would like to upgrade to Windows 10. Testing on the same Dell E6420 under Windows 10, however, is working for silence detection, but not calibration. The Silence Detector app always shows the same volume regardless of the sound card volume. Even if the sound card volume is set to zero, the calibration does not change.
At this time, I have no plans to upgrade to Windows 10, but eventually Windows 7 will become obsolete.
I just wanted point out that there is a problem with your silence detector on Windows 10, at least on my Dell Latitude E6420. Whether this calibration is a problem on other computers, I don't know, but I just wanted to bring this to your attention.
Thanks again for this very important app!
