Audio
three-dimensional space with a grid of thousands of evenly distributed virtu- al microphones at specific positions. This results in a very high degree of spatial resolution. A virtual micro- phone is any one of the thousands of predetermined locations (a spatial fo- cus point) in three-dimensional space. The microphone system monitors all the thousands of virtual microphone positions in real time and determines which to focus on based on proprietary logic.
Because the virtual microphones are evenly
distributed throughout the
space, a participant walking around the room is tracked and followed effort- lessly. People can be sitting, standing or even walking to a flip chart or touch display on the edge of the room – their voices are always picked up. Because the virtual microphones are spaced close together, the handoff and tran- sition between virtual microphones is seamless, creating a consistent audio experience for the person on the other end of the call. This avoids disruption from big switches between discrete microphones or beamformer zones, which can alter the background noise and volume of the person talking.
Surpassing the status quo
Microphone Mist technology creates a natural meeting experience that is fundamentally
different than other
audio approaches. With discrete mi- crophone systems, seeing the physical microphone in the room often causes participants to modify their behavior to be within the pickup range. They may even need a lapel mic or handheld mic if they walk out of the coverage range of the static-positioned microphones. A beamforming microphone system is typically configured to cover specific areas in the room. If people leave that
area, their voices may not be picked up. Plus no one can see where the beamforming coverage starts or ends, which can create situations where the audio will drop off unexpectedly when participants move around the room or change from sitting to standing. Microphone Mist technology has nei- ther of these limitations, so partic- ipants in the room can act and talk naturally. It’s also much more flexi- ble. With the demands on spaces to become adaptable to multiuse ar- rangements, the benefits of having thousands of evenly distributed virtual microphone positions becomes clear.
Why higher resolution matters
By taking advantage of thousands of discrete 3D virtual microphone posi- tions instead of relying on broad cov- erage zones, Microphone Mist tech- nology results in audio conferencing systems that are more precise and capable. Put another way, if we move from using broad coverage zones – that either aim in the direction of a desired sound source or use a broad omni coverage pattern – and instead detect and analyse sound at many thousands of positions in a room, we have the opportunity to reimagine au- dio conferencing.
By applying a new approach that ana- lyzes a room three dimensionally, au- dio characteristics can be determined for each one of thousands of locations in a room. That wealth of sound in- formation can then be independently evaluated for desirability and quality, and automatic adjustments to the sys- tem can be made accordingly. People talking can be treated differ- ently from unwanted noise sources, such as HVAC systems. Even common noises such as a people typing can be defocused by the system. For example,
if you are typing and talking on a call, a microphone system with a broad cov- erage pattern will pick up both sounds equally and treat them the same. Be- cause Microphone Mist technology re- solves the space to thousands of focus points, it can focus on the exact spot where a voice is located, meaning that the keyboard sounds are naturally re- duced in level. HVAC and noisy displays can be treat- ed differently by Microphone Mist technology using intelligent sound tar- geting technology because the system knows the position of the HVAC vent in 3D space. It can adapt in real time, fo- cusing on the active participants and not the bothersome noise sources in the room.
Ready for the future
In uncertain times, where physical dis- tancing and other COVID requirements demand more of our spaces than be- fore, it is more important than ever to select and install an audio system that’s up to the challenge. Systems need to be able to adapt in a future forward manner that accommodates new and scalable technologies. Microphone
Mist technology rep-
resents an entirely new approach to the acoustic space. It opens up a world of possibilities, where hanging one audio conferencing system on a wall results in true full-room audio coverage. And even more importantly, this novel ap- proach has the potential to continue to deliver improvements, meaning that the system you buy today only gets better with time.
