Since you mention it, I got to thinking about whether we can have a microphone equivalent to the physical covers for webcams -- that is, a physical means that ensures the device can't detect anything usable, even if an attacker was able to turn it on without you knowing.
Something like, a vibrating module that you don't really notice but which clouds out any sounds the microphone would pick up (or, to go your route, injects fake audio). You turn it on when you want to be sure the microphone isn't listening, just like you can cover the webcam.

- briandear 6y agoIt does work, but you can have filters that can remove that noise electronically enough to get some actual voice signal. Faucets along with whispering directly in the ear would work. But a better choice is to simply write on a piece of paper instead of talking.
- plutonic 6y agoYou mean something like this [0]? You could use this to trick your computer/phone into using the audio jack for its microphone, but since the mic-lock passes no usable signal, you'll be better protected. It doesn't otherwise incapacitate the internal microphone, though.

- SilasX 6y agoIt would need to block the microphone itself that picks up ambient noise -- I don't think there's anything on e.g. a MacBook Air that you could plug that into and block sound.
