I know of a startup in Berlin that was working on the ability to focus sound at any given point in the room with minimal leakage. The application allowed three people in three parts of the room to listen to completely different music without any interference. I thought it was uber cool! Now with this innovation, this just got even cooler. I wonder when these technologies will become affordable for the masses.
WFS is stereo++. The sweet spot is much wider, and if you move around you hear a convincing illusion of getting closer/further from the virtual sound sources.
But it's pretty much the state of the art, and impossibly expensive for home use. I'm finding it hard to imagine how it would be possible to distribute sound to various points around a room with negligible leakage or interference.
