University Uses Array Microphones for Distance Learning, Teleconferencing
SUDBURY, Mass.—June 20, 2006—Acoustic Magic has announced that Ohio University is using its Voice Tracker array desktop microphone for distance learning and large group teleconferencing applications.
According to the announcement, the Voice Tracker works by locating a talker and electronically steering a “listening beam” in that direction to create spatial filtering, ensuring that sounds from other parts of the room are not picked up. In addition, it reportedly removes “stationary” background noise with digital noise reduction algorithms. The Voice Tracker can be connected to a PC through a sound card, or through a USB port using an optional USB adapter.
“The Voice Tracker is great for 15- to 20-person seminars and meetings, at ranges up to 20 feet,” said David Underwood of the College of Business at Ohio University, in the announcement. “Although I could put lavaliere mics on the professors, the Voice Tracker gives [them] freedom to not worry about microphone placement and drop-out; and [it] does a great job picking up the questions from the back of the room. We have been configuring it with an audio mixer in our international and regional graduate programs for Adobe Macromedia Breeze and SKYPE conferences since December.”
