Acoustic Magic Voice Tracker 2 II Quick Start Manual

The Voice Tracker™ II Array Microphone
The Voice Tracker™ II starts with Acoustic Magic's unique, customer proven, patented scanning
beam array microphone technology, which spatially filters undesired sounds and noise over a
360° field of view. But it has been designed to enhance its applicability for video and audio
conferencing , while retaining its attributes for meeting and lecture recording, speech recognition,
voice control, and security monitoring.
Effective at Long-Range
The Voice Tracker™ II creates an exceptional signal to noise ratio by increasing its signal pickup
while reducing room noise. It accomplishes room noise reduction through a two-stage process.
First, it minimizes unwanted background noise and reverberation by beamforming. Its digital
signal processor creates a "listening beam" (like a searchlight) that automatically and
electronically focuses on the talker, spatially filtering sound from other directions. Then its
proprietary noise reduction algorithms diminish the remaining background noise and
reverberations. The Voice Tracker™ II increases its sensitivity by constructively adding the
output from its six "always on" microphone elements. As a result, the Voice Tracker™ II has
range of more than 20 feet for conferencing, meeting recording, and home automation
applications; and a range of several feet for hands-free/headset free full vocabulary automatic
speech recognition applications.
Full Duplex operation for VoIP and conventional conferencing
The Voice Tracker™ II has a high performance acoustic echo canceller built in. This AEC,
combined with, a mute button, and the Voice Tracker™ II's long-range, make it ideal for
conferencing and telephony (speakerphone) applications.
Portable
The Voice Tracker™ II is half the size of the original Voice Tracker™, and fits easily into a
briefcase. It can be powered through its USB connection, eliminating the need to carry a wall
power converter and making it operable in any country.
Easy to use
Our patented beam steering technology, noise reduction algorithms, and AEC, all operate from an
internal DSP. No software needs to be loaded on your PC, and there is no drain on your
computer's processing capability. There are no moving parts, so the Voice Tracker™ II is rugged
and reliable.
