Interact Devices Selects Acoustic Magic’s Voice Tracker Array Microphone for their Video Conferencing System

Sudbury, MA May, 2006 – Finding a microphone that can pick up all the talkers in a large group meeting or distance learning class, while suppressing background room noise so the conversation can be heard at the far end, is a challenge. Often, conferencing systems employ extension or satellite microphones, which are expensive and take up table space.

Interact Devices, Inc. has found the solution in the Voice Tracker™ desktop array microphone, and selected it to be an integral part of their new, unique video conferencing system.

John Wilkerson, Vice President of Technology for Interact Devices, Inc states “we wanted a microphone that would match our high quality video (up to 30 frames per sec). We choose the Voice Tracker™ array desktop microphone because its signal to noise ratio is so good it can cover the entire room. Its exceptional signal to noise ratio also makes our acoustic echo canceller work better.”

According to Bob Feingold, founder of Acoustic Magic, Inc., “users like the Voice Tracker™ for large group conferencing applications because, as a single microphone, it is cost effective and can free up table space.” Users sometimes mount the Voice Tracker™ on the ceiling, further reducing table clutter and installation cost.”

The Voice Tracker™ array microphone locates a talker and electronically steers a “listening beam,” like an acoustic searchlight, in that direction. This creates spatial filtering; sounds from other parts of the room are not picked up. In addition, the Voice Tracker™ removes “stationary” background noise with digital noise reduction algorithms. This two-stage noise reduction, coupled with increased sensitivity since the Voice Tracker’s eight microphone elements are used continuously and constructively, give the Voice Tracker™ outstanding range and sound quality.
