Microphone Mist technology

Powering the HDL300 system is patented Microphone Mist technology, the revolution that audio conferencing has been waiting for. It fills rooms with thousands of virtual microphones so people’s voices are picked up everywhere — making Nureva the easiest and most cost-effective way to get true full-room audio coverage in all your spaces.


The virtual mic difference

  • Full-room microphone pickup
  • Intelligent Sound Targeting
  • Position-based gain control
  • Continuous autocalibration
  • Simultaneous processing

With 8,192 virtual microphones filling your space, there’s always one nearby. People can speak and act naturally in meetings and classes and be confident they will be heard by those who are remote.

HVAC and other unwanted sounds can seriously affect your audio performance. So instead of trying to suppress them after the fact, we use adaptive learning algorithms to preemptively ignore them.

We apply gain separately to each sound in a space based on its position, creating a natural listening experience for remote participants.

With our technology, you never need to recalibrate your systems manually. Your HDL300 is automatically and continuously adapting to changes in your room’s acoustic profile.

Microphone Mist technology listens to, and processes, all virtual microphones simultaneously. Conversations sound natural even when more than one person is speaking at the same time.

Built for flexibility

With full-room microphone coverage, simple installation and cloud-based device management tools, the HDL300 system is the easiest and most cost-effective way to equip your large rooms.

Easy audio for divisible rooms

Do you have rooms with movable dividers or walls? Get great audio no matter how you’re using the space. With the addition of an Ethernet switch, the microphone and speaker bars from two HDL300 systems can work together as a single system, providing audio coverage up to 30' x 50' (9.1 x 15.2 m). It’s easy to change back to running the two systems independently when the room is divided.

Features & updates   



The HDL300 system is available in over 35 countries, with more coming. Find a distributor.

No — all you need is a computer running a UC&C platform. No extra speakers, components or DSP are required. To get updates and manage the system, be sure to install Nureva Console on your in-room computer.

Yes. Although the HDL300 comes with integrated 20-watt speakers, you can also connect it to your own speakers if you prefer.

One of the most popular features of the HDL300 (and all Nureva systems) is the fact that we keep adding features and making improvements. To get regular firmware updates, be sure to register your system in Nureva Console.

When two people talk at the same time, the HDL300 system focuses on the stronger signal (the louder voice), while the other voice drops into the background. The effect is as if you were standing in the room close to the louder talker, but are also aware that someone else is speaking at the same time.

The system monitors and adjusts to the location of a talker 10 times per second.

Yes, but please note that not all UC&C systems support stereo audio.

Setting up the HDL300

At Nureva, we keep things simple. It’s why installing the HDL300 system is an easy procedure that usually takes less than an hour. Hang the microphone and speaker bar on the wall (with just two screws and plugs), run an Ethernet cable to the connect module and then a USB cable to a computer with UC&C software and you’re ready.
