Key features
Acoustic Echo Cancellation (AEC)
Acoustic Echo Cancellation removes echo from the microphone audio input while reducing far-end echoes enabling XVF3800 to extract clear voice signals even with high-volume speaker output.
Noise Suppression
Noise suppression nulls stationary and non-stationary diffuse noise sources, for example air-conditioning and road noise where the frequency characteristics do not change over time. This enables accurate, consistent voice capture.
Adaptive Multiple Beamformers
The free-running and focused beamformers track both stationary and non-stationary voice sources, identifying the direction of arrival (DoA) and isolating the voice of interest to enhance double talk and dereverberation performance.
Automatic Gain Control (AGC)
The configurable and flexible Automatic Gain Control tunes the output channels for optimal voice communication. Ideal for passing Teams and Zoom certifications.
