Nureva supports third-party camera tracking with an audio API

Patented Microphone Mist technology from Nureva Delivers accurate sound localization data for third-party camera integrations in a room with thousands of virtual microphones.

The new device API Sound Localization from the Canadian audio conferencing solutions specialist transmits data that identifies where participants are speaking who are in a room to direct and change cameras, so that those who are remote can follow the conversations without problems and see the interlocutor.

This development is particularly suitable for use in Large rooms in which a larger number of participants usually attend, as in meeting space, Higher Education Classrooms, Etc.

Unlike typical microphone systems, that rely on assigning areas to the camera presets and only provide directional data from the sound source or unwanted sound sources (Heating Equipment, Ventilation and air conditioning, Hvac), of a wall speaker etc; Nureva Used virtual microphones as collection points.

The processing power of the technology Microphone Mist, Patented by the company, Filters out unwanted sounds that make it difficult for remote participants to follow the presenter. Using this API, Camera companies have easy access to the address, location and sound level of the Nureva audio system being used.

Sound locations are communicated multiple times per second to allow Automatic camera adjustments depending on the location of the active speaker or the need to shift focus between multiple speakers.

Available through the company's developer toolkit (Nureva Developer Toolkit), the Sound Localization Devices API was created as part of a program to work with, with leading camera companies, in integrating their PTZ cameras with Nureva audio systems and providing customers with a better audio and video experience.

Integrations with Aver and Lumens, among other companies. Earlier this year, Nureva Console cloud-based monitoring of any USB-connected third-party camera, making it easy for IT staff to remotely monitor cameras and ensure they are working properly in meeting rooms and classrooms.

"The use of Microphone Mist technology for camera tracking is a breakthrough that opens up many exciting possibilities for capturing and using sound localization data," he said Nancy Knowlton, CEO of Nureva-. We're thrilled to be working with leading camera manufacturers to enable this functionality and deliver the kind of integrated audio and video experience customers are asking for.".

Microphone Mist vs. beamforming

Many traditional audio systems use microphone technology beamforming, that collects all the sounds that are produced within the directional beams emanating from the microphone array.

As they point out from Nureva, This directional approach limits the degree to which precise sound locations can be identified and poses a challenge in distinguishing desirable sounds (A Person Who Speaks) of the annoying (The Crunch of Paper) Inside a Beam.

These issues limit how accurately sound location data can be used for camera tracking. Microphone Mist technology avoids these problems by filling a space with Thousands of pick-up points that act as individual microphones, locating sound more accurately and differentiating desired sounds from unwanted ones.

The Nureva Sound Localization Device API, company of which Crambo is an official partner in Spain, is now available through Nureva Developer Toolkit at no additional cost to the company's customers.
