Unlike conventional microphones, or first generation array microphones, which have a fixed “listen” direction, Acoustic Magic Voice Tracker™ Array Microphones automatically locate the active talker and electronically steers a “listening beam” in that direction. It can direct its “listening beam” over a 360 degree range, creating a wide field of view. For Meeting Recording or Lecture Capture or Conferencing Applications, the Voice Tracker™ Array Microphones capture all the participants since the “listening beam” moves from one talker to the next in milliseconds. For speech recognition applications, it is no longer necessary to sit rigidly in front of the microphone. The user is free to lean backwards, sideways, or even move around.
The Voice Tracker™ I Array Microphone was the original implementation of our patented, automatically and electronically steering, “listening beam” technology. It has been in production since 2002, and has proven to be extremely rugged and reliable.
