microphone mist™ technology

This is what a revolution sounds like

Microphone Mist technology is the brains behind the Nureva™ HDL300 audio conferencing systems. It leaps past traditional audio technologies, filling a space with thousands of virtual microphones to provide true full-room pickup. It’s an entirely new approach to meeting room microphones that’s changing conference call audio.

Virtual microphones: the magic behind Microphone Mist technology

Microphone Mist technology fills a room with 8,192 virtual microphones (16,384 with the Dual HDL300 system). A virtual microphone is an individual “pickup point” created when two or more physical microphones (12 are in an HDL300 bar) work together through proprietary processing algorithms to focus their pickup patterns on a configurable zone. Thanks to advanced processing power, Microphone Mist technology listens to each virtual microphone simultaneously and zeros in on the predominant sounds and optimizes them for clear conversations – no matter where meeting participants move in the room.

Compare coverage

Traditional beamforming and tabletop omnidirectional meeting room microphones leave dead zones where people can’t be heard – especially when they move, interact and collaborate. It’s why we created Microphone Mist technology. Learn more from our Brief Guide to Audio Conferencing Systems.

Intelligent sound targeting eliminates unwanted sounds

HVAC and other unwanted sounds can seriously affect conference call audio. Traditional systems use “post-sound” filters that require substantial processing resources to suppress sounds. But new intelligent sound targeting (IST) in our Microphone Mist technology takes a “pre-sound” approach. Using adaptive learning algorithms, IST preemptively identifies and learns unwanted sounds and then simply stops picking them up. It’s another feature other technologies can’t match.

A powerful platform for how you work today – and tomorrow

With advanced system processing capability (15,000 MIPS for the HDL300, 25,000+ MIPS for the Dual HDL300), Microphone Mist technology delivers vital audio benefits, including full-duplex transmission, continuous autocalibration, acoustic echo cancellation, built-in sound masking and position-based automatic gain control. But we also designed Microphone Mist technology to help drive a road map of innovations (using adaptive learning algorithms, for example) that will continually advance the audio landscape – and your audio conferencing experience.

Only in the HDL300 systems

Revolutionary Microphone Mist technology was developed by Nureva engineers exclusively for the HDL300 systems.

HDL300 audio conferencing system in black

HDL300 system

US$2,999 MSRP*

For spaces up to 30' x 30' (9.14 x 9.14 m). The HDL300 system’s 8,192 virtual microphones provide true full-room pickup for any room configuration. Whether you’re seated at a table, holding a stand-up meeting or working at displays, you’re covered.

Dual HDL300 audio conferencing system in black

Dual HDL300 system

US$5,499 MSRP*

For spaces up to 30' x 50' (9.14 x 15.24 m). With just two microphone and speaker bars, the Dual HDL300 system’s 16,384 virtual microphones provide true full-room pickup for any room configuration. And it costs a fraction of traditional systems for large spaces.
