Background the sound barrier

The quality of audio conferencing is a critical element of the modern workplace. Businesses thrive on working collaboratively with clients and colleagues located inside and outside of the corporate office.

Nureva’s breakthrough Microphone MistTM technology delivers 16,384 virtual microphones in the largest of meeting spaces for true full-room pickup and coverage. Quality and quantity – at a fraction of the cost of conventional systems.

Large Rooms. Big audio challenge.

The science behind the technology

The Dual HDL300 takes a completely new approach to the science of meeting toom microphones. The Microphone MistTM  technology will transform conference call audio in large spaces by placing up to 16,384 virtual microphones throughout a meeting room to pick up sound from any location. Enabled by real-time hardware, the solution uses sophisticated algorithms to simultaneously process sound from all virtual microphones to provide remote participants with the highest quality listening experience.

The Dual HDL300 custom audio processing units are capable of handling up to 25,000+ MIPS. This power is used to create the quality listening experience, the virtual microphones, continuous self-calibration, simultaneous echo cancellation, position-based automatic gain control and sound masking. Listening to all microphones simultaneously, the systems dynamically select the one closest to the speaker, ensuring the best quality sound for people outside of the room.

Fully plug and play, the self-calibration feature means there’s no technical setup or adjustment for the room. As the integrated microphone and speaker bars easily mount to the wall, it helps to eliminate table clutter and distracting noises while still picking up and delivering clear sound to all participant.

Quality, cost and convenience

Traditional solutions for audio conferencing in large rooms involve a big commitment in terms of time, budget and planning. New ways of working have placed greater emphasis on collaboration, decision-making and creativity within meeting spaces involving numerous physical or remote participants. The demand needs to be met with a cost-effective solution that can be installed quickly and simply yet delivers the highest quality listening experience.

Whether participants are leaning against a wall in a conference room or connecting via a laptop in a hotel lobby the Dual HDL300 offers truly disruptive technology. Audio conferencing goes way beyond simply sharing voices, an idea can be voiced and heard from anywhere, the back of the room, in front of a display or even the other side of the continent. The system resolves the common issues of poor quality and poor audio pickup, especially in large meetings with participants moving around the room.

The Dual HDL300 will capture dynamic discussions and ensure remote participants never miss a word even in large conference rooms. A performance that will transform your collaborative meetings and change your whole approach to conference call audio.
