The Voice Tracker™ array microphone can pick up talker throughout the entire room, it has often been used for conferencing application. The addition of a high-quality AEC algorithm to our internal DSP is the main differentiating feature of the Voice Tracker™ II Array Microphone, but it has several other attributes as well.

A crucial audio requirement for conferencing is the elimination of acoustic echo (sound from the far end talker picked up by the open mic and sent back). The Voice Tracker™ II Array Microphone’s internal AEC algorithm provides performance that rivals or exceeds that of AEC boxes costing several thousand dollars.

Connect the Voice Tracker™ II Array Microphone to your PC based VoIP software and eliminate the need to use headphones; all the near end talkers will be heard, even if they talk softly or are far away from the mic and the far end talker will hear no echo.

Acoustic Echo occurs when an open mic picks up a far end talker (from the loudspeaker) and sends it back to the far end talker (as an echo). In the above charts, the bottom chart shows the audio from near end and far end talkers transmitted by the Voice Tracker™ II with acoustic echo cancellation off. The top chart shows a similar audio transmission with the AEC turned on.
