Features

This technology was created to improve audio quality, compared to other similar technologies through various audio processing features: * a dynamic audio leveling to focus on the human voice, and to equalize participants audio power easing listening * a spatialization of audio to improve voice clarity and reduce fatigue by preventing speech overlapping when multiple participants are talking at the same time * a

noise reduction Noise reduction is the process of removing noise from a signal. Noise reduction techniques exist for audio and images. Noise reduction algorithms may distort the signal to some degree. Noise rejection is the ability of a circuit to isolate an u ...

to limit unwanted background sounds in noisy environments * an echo reduction to limit audio reinjection when input and output devices are placed close together while, at the same time, avoiding to cut back on bandwidth usage and network resilience, through the use of heavy compression.
