Nureva supports third-party camera tracking with an audio API
Patented Microphone Mist technology Nureva Delivers precise sound localization data for third-party camera integrations in a room with thousands of virtual microphones.
The new device API sound localization from Canadian audio conferencing solutions specialist transmits data that identifies where participants in a room are speaking to direct and change cameras, so that those who are remote can follow the conversations without problems and see the interlocutor.
This development is especially indicated for use in large rooms in which a larger number of participants normally attend, as in meeting space, higher education classrooms, etc.
Unlike typical microphone systems, which depend on the assignment of 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), from a wall speaker etc.; Nureva uses virtual microphones as collection points.
The processing capacity of the technology Microphone Mist, patented by the company, filters out unwanted sounds that make it difficult for remote participants to follow the presenter. Through this API, camera companies have easy access to address, location and sound level of the Nureva audio system being used.
Sound locations are communicated several times per second to allow for automatic camera settings based 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 Location Devices API was created as part of a program to work, with the main camera companies, in integrating its PTZ cameras with Nureva audio systems and offering customers a better audio and video experience.
Integrations are currently being made with AVer y Lumens, among other companies. Earlier this year it was added to Nureva Console Cloud-based monitoring of any USB-connected third-party cameras, making it easier for IT staff to remotely monitor cameras and ensure proper operation in meeting rooms and classrooms.
“The use of Microphone Mist technology for camera tracking is an advance that opens up many interesting possibilities for the capture and use of sound location data,” he says. Nancy Knowlton, Nureva CEO. “We are delighted to be working with leading camera manufacturers to enable this functionality and deliver the type of integrated audio and video experience that customers are asking for.”.
Microphone Mist vs. beamforming
Many traditional audio systems use microphone technology beamforming, which picks up 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 of identification of the precise locations of sounds and poses a challenge in distinguishing desirable sounds. (a person who speaks) of the annoying (the rustle of paper) inside a beam.
These issues limit the precision with which sound location data can be used for camera tracking.. Microphone Mist technology avoids these problems by filling a space with thousands of collection points which act as individual microphones, locating sound more precisely and differentiating desired sounds from unwanted ones.
The Nureva Sound Location Device API, company of which Cramp is an official partner in Spain, is now available through Nureva Developer Toolkit at no additional cost to the company's clients.
