Microsoft Research had papers on speaker arrays that allowed speaker focus and noise cancelling a couple of decades ago. I think the technology eventually ended up in the Kinect. I think Cisco had something similar in their large screen meeting room video conferencing systems that could do positional audio tracking of multiple people. Could be wrong, but I think that was at least 10 years or so ago, if not more. |
