So does that mean that software will always have mic on?

  Maybe, but there's no reason for it to send any audio anywhere while it's parsing ultrasound, so not a privacy problem.

    Until software is compromised or simply has a bug that stream audio somewhere.

      In which case it could have just turned on the microphone itself?
      • Gonzih 7y ago
        Software that already is listening has more vectors of attack to put it simply. I'm not a fan of features that compromise privacy and security for the sake of convenience.

          That's really nonsensical. Nothing about using an audio input makes code more vulnerable. The interface is always there if the hardware is.

    If software that continuously listens to the microphone is normal this makes it harder to keep track of apps that should not do that.

  The presentation implies that you have to click the "share screen" button before your computer will try to detect the ultrasound signal.
