But think about this - these same devices are being used to record HD or even UHD video - I'm sure folks recording such would want super-low fidelity audio to go with the high-quality visual....
I use a very-high tech system to prevent spies from enabling my laptops and ipads from video recording me - Post-It notes taped over the camera lenses. When I'm walking around the house half-naked I don't want to cause a spy to have a heart attack. As for audio, it's just anti-liberal rants and no one wants to listen to that.
