Nureva adds third-party camera tracking to its audio API

Thanks to Microphone Mist technology, the new API Nureva transmits data that identifies where people are talking within a room. This way you can direct the camera and remote participants can follow conversations and see who is speaking.

Nureva has announced that his Audio API Enables camera tracking with precise sound location data for third-party camera integrations.

Technology Enabled Microphone Mist, that fills a room with thousands of virtual microphones, New Sound Location Device API transmits data that identifies where people are speaking within a room to direct and switch cameras so remote participants can more easily follow conversations and see who is speaking.

This is ideal for large rooms that can accommodate a large number of participants, such as a higher education classroom or a large meeting room or board room.

Unlike typical microphone systems that rely on mapping areas to camera presets and only provide directional data from sound sources or target unwanted sources, such as HVAC fans or a wall speaker, Nureva uses virtual microphones as pickup points to locate sound sources.

The advanced processing power of Microphone Mist technology filters out unwanted sounds that make it difficult for remote participants to follow the presenter.

Using the Nureva API, camera companies have easy access to address, precise location and sound level of the audio system being used. Sound locations are reported multiple times per second to allow automatic camera adjustments based on the location of the active speaker or the need to shift focus between multiple speakers.

Available through Nureva Developer Toolkit , The Sound Location Device API was created as part of a program to work with major camera companies to integrate their PTZ cameras with Nureva audio systems to offer customers a better audio and video experience..

Integrations are currently being made with AVer and Lumens, among other camera companies. At the beginning of this year, Cloud-based monitoring of any USB-connected third-party cameras added to Nureva Console. This makes 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 to enable camera tracking is a breakthrough that opens up many possibilities for sound placement”, comment Nancy Knowlton, CEO of Nureva.

Microphone Mist Technology

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

This directional approach limits the degree to which sound locations can be identified and creates a challenge in distinguishing desirable ones. (a person speaking) and the undesirables (paper whisper) 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 pickup points that act as individual microphones.. Creates the opportunity to identify sound locations accurately while distinguishing between desirable and undesirable sounds.
