The Voice Tracker™ II automatically and electronically steers a listening beam towards the active talker. This enables pickup over an entire room. This 20 foot pickup range Is accomplished in two ways. First, sensitivity was increased compared to conventional microphones by constructively adding the output of six separate, always on microphone elements. Second, spatial filtering and background noise reduction are used to eliminate sound from all areas in the room except that space around the active talker, so the increased sensitivity is not corrupted by noise.
The Voice Tracker™ II also incorporates embedded acoustic echo cancellation, which eliminates annoying echo at the far end.
The Voice Tracker™ II is powered by USB and has a USB as well as analog audio output.
