Efficient spatial separation of speech signals

  • US Patent No. 7505601
  • Issued: March 17, 2009
  • Status: Active

A computationally efficient method and device for adding spatial audio capabilities to new and existing centrally switched communication systems without modifying the internal operation of the systems or the switching architecture by producing a digitally filtered copy of each input signal to represent a contralateral-ear signal with each desired talker location and treating each of a listener's ears as separate end users.
