Two approaches to audio coverage
Microphone MistTM technology
Microphone Mist technology fills a room with thousands of virtual microphones (individual “pickup points”). No matter how far apart in-room meeting participants are or which direction they face, a virtual mic is always close by. There are no dead zones. And thanks to advanced processing power, Microphone Mist technology listens to each virtual microphone simultaneously and zeros in on the predominant sounds, optimizing them for clear conversations. Unlike other systems, it also ignores consistent noise sources from HVAC, displays or computer fans. The result is a clear and consistent audio experience that makes remote team members feel like they’re in the room.
Beamforming technology
Many traditional audio conferencing systems employ beamforming technology, which picks up sound in defined “lobes,” usually pointed at fixed positions around a meeting room table. Pickup can be adequate, as long as participants stay clustered around the lobes. However, if meeting participants move outside the lobes – to present at a display or spread out within the room – they may enter a dead zone where pickup can be diminished, making it difficult for a remote caller to hear. And if a talker is between lobes, the audio may drop off or rise sharply, which can be an annoying and even fatiguing experience for remote participants.

Active Zone Control
An extension of Microphone MistTM technology, Active Zone Control emphasizes pickup of the virtual mics in a controlled “active” zone at the front of the room while inhibiting pickup from the virtual mics in the rest of the space. Lecturers or presenters can leave lapel mics, headsets and the hassles of changing batteries behind. They can move freely in the active zone, confident that remote participants can hear them above room noises.
Partial zone
Set the active zone for the required dimensions at the front of the room, and the person speaking can be heard more clearly while sounds and voices from the rest of the space are suppressed. It adds up to better audio for remote audience members and lecture capture.
Full zone
When it’s time for group discussions or questions from the class or audience, switch to the full zone setting to activate all the virtual microphones in the space so everyone in the room can be heard by remote participants.

Intelligent Sound Targeting
Intelligent Sound Targeting (IST) identifies and stops targeting persistent undesirable sound sources like HVAC and display fans to give remote callers a better listening experience.
More clarity, less noise
HVAC and other unwanted sounds can seriously affect conference call audio – ultimately causing frustration and even reducing productivity. But IST, a feature of Microphone MistTM technology, takes a groundbreaking approach to this problem. Instead of attempting to suppress undesired sounds completely, it uses its intelligent sound identification capabilities to mitigate the negative impact of those sounds in an elegant and efficient manner. You hear voices better and unwanted noises less.
Pre-processing vs. post-processing
Achieving rich, full-room audio pickup in noisy meeting and learning spaces has always posed a significant technical challenge. Traditional systems use “post-processing” filters to suppress sounds. However, these require substantial processing resources and are not always effective. But IST takes a “pre-processing” approach. Using adaptive learning algorithms, IST preemptively identifies and learns unwanted sounds and then simply stops targeting them. It’s a feature other technologies can’t match.
