I have been continuing my research/experimentation with directional audio.
This beamforming linear speaker array is a test platform I designed to see what kind of results I can get and if it is possible to make this technology more affordable.
Don’t know what beamforming is? Check out the wiki page
And here is some info on linear speaker arrays
In the end, it is my goal to be able to focus sound at specific points in a room. Microsoft and THX have been working on this technology for home and theater audio systems but my focus, as always, is on something completely different.
