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.
