Over 20 years ago I had a Toshiba Tablet PC convertible that had a beam forming array of microphones and it came with software that let you point where you wanted to record from.
The use case was for lectures, you could tell the laptop to just record from behind it, pointing the beam in the direction of the professor.

Amazing idea and something I haven't seen since.
