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.
Acoustic Magic has been manufacturing and selling the Voice Tracker I scanning-beamforming array microphone since 2002. More than 18,000 have been sold. It has been proven to be reliable, easy to use and capable of picking up talkers clearly at ranges as far as 30 feet, with a 360 degree field of view.
We are now excited to introduce the Voice Tracker III, which is based on the pioneering and proven technology of the Voice Tracker I, but has 2 dB better signal to noise ratio, and a flatter frequency response curve, leading to a “brighter” sound quality.
Voice Tracker™ array microphones incorporate 5 important technology innovations:
-Automatic and electronic scanning “listening beam” with a field of view of 360°.
-Constructive addition of multiple microphone elements for long range.
-Spatial filtering for noise reduction.
-Rapidly converging AEC algorithm (Voice Tracker II only).
Embedded algorithms for ease of use.
