Does tape actually provide enough impedance to prevent surveillance through your microphones? Seems like all an attacker would have to do is amplify (and possibly filter) the audio a bit.
- greglindahl 13y agoI turned up the mic all the way, did a skype test call. I could hear myself if I shouted (input level=0). If I talked at a normal volume level, it was audible (and the input level showed as 2/15. I might try a couple of layers of tape... EDIT: Yeah, 2nd layer of tape = 0 input level even if I shout really, really loudly. You can't imagine how much my coworkers are enjoying this experimentation!
- pasbesoin 13y agoI wondered about tape along with a suitable sound-dampening material, so this "seat-of-the-pants" experiment is of interest to me. I'd want something more certain for a higher security situation, but this might do me for some "casual" use cases.
- superuser2 13y agoSkype has a noise gate - any play on the microphone below a certain level is cut off. Someone with direct access to your microphone can listen without the noise gate and might still hear.
