Let you understand Nureva's Microphone Mist™ technology
Each Nureva audio system brain uses Microphone Mist™ technology. Microphone Mist™ technology can evenly fill the entire space with thousands of virtual microphones. Compared to traditional long-distance pickup systems, which may still have blind spots despite using multiple physical or logical microphones, the Nureva audio system can achieve true large space coverage with just 1-2 devices. Even with slight adjustments to the space layout during use, the real-time automatic calibration function can continuously optimize the listening experience, allowing meeting participants to move and converse naturally and easily while maintaining a safe distance from team members.
Beamforming technology has been widely used in the video conferencing field in recent years, effectively solving the problem of long-distance audio pickup. Beamforming technology can accurately determine the direction of the speaker, and when combined with DSP processing equipment, it can achieve very good results through professional design and debugging. If the design is not professional enough, a series of issues such as coverage dead zones may arise. Similarly, if the system integrator lacks sufficient debugging experience and uses AGC processing methods to adjust gain based on the volume of sound signals, issues such as fluctuating volume may occur.
Microphone Mist™ technology can accurately determine the speaker's position and calculate the required gain based on the inverse square law. Therefore, when speaking from any position in the space, the output volume remains very stable. Even when moving while speaking, the gain adjustment is very smooth, and someone at the far end may not even notice that the other person is speaking while moving.
Based on Nureva's
Microphone Mist™ technology
can achieve the following functions:
Whole house coverage
Nureva's Microphone Mist™ technology can achieve true whole house coverage. Depending on the product model, the number of virtual microphones and applicable space area vary. In small spaces, within a range of 5.5x5.5m, it can fill 4096 virtual microphones; in medium spaces, within a range of 7.6x7.6m, it can fill 8192 virtual microphones; in large spaces, within a range of 9.1x15.2m, it can fill 16384 virtual microphones. Thousands of virtual microphones will be evenly distributed in the applicable space (ensuring uniform distribution density of virtual microphones in that space), achieving true full coverage within the space. At this point, regardless of whether facing or turning away from the microphone, the Nureva audio system can deliver clear sound to the far end.
Multiple speakers
Multiple speakers at the same time is an important indicator of the convergence speed of DSP echo cancellation processing. Any DSP audio processing system used for echo cancellation needs to accurately know the relative position of the speaker to the speaker to achieve a relatively ideal echo cancellation effect, which helps improve the convergence speed of echo cancellation. If the relative positioning of the speaker and the speaker is not precise enough, achieving a relatively ideal echo cancellation effect will require a lot of convergence time, thus affecting the experience. Conversely, if the system can accurately determine the speaker's position, the echo cancellation processing can converge instantly, resulting in a better experience. Even if some systems have limited DSP resources, they can directly use parameters that are close to well-converged positions, and minor imperfections can be adjusted in real-time, significantly improving the convergence speed of echo cancellation during multiple speakers.
Intelligent sound localization
Sound localization mainly includes noise localization and speaker position localization. Accurate noise localization facilitates DSP modeling to eliminate steady-state noise. Speaker position localization can provide basic positional information for location-based automatic gain control, serving as the calculation basis for gain based on location. In addition, intelligent sound localization can also provide precise coordinate data for camera tracking, guiding the camera's shooting direction, and based on accurate positional information, it can also guide the camera's zoom.
Real-time optimization and adjustment
When there are slight changes in the environment within the space, the Nureva audio system can make real-time adjustments based on the actual environment to ensure that the audio signal of the speaker on this end is always at its best effect when delivered to the far end.
