XMOS launches the XVF3800: high-performance voice processor for collaboration applications

XMOS announces the launch of its XVF3800 voice processor, designed to deliver a high-performance, rapid time-to-market solution for enterprise and consumer voice conferencing platforms. The four-microphone processor is intended to enable Microsoft Teams and Zoom certification in conferencing devices, video bars, portable speakerphones, PCs, gaming monitors and collaborative display solutions. State of the art algorithms provide high-quality audio in challenging environments, while the processor itself enables engineers to fully optimise performance based on the specific acoustics of the product at hand. Key features include: Acoustic echo cancellation (AEC) – removes far-end echoes picked up by the microphones, which enables the XVF3800 to extract clear voice signals even with high-volume speaker output Adaptive multiple beamformers – tracks both stationary and non-stationary voice sources, identifying the direction of arrival, and isolating the voice of interest, improving double talk and dereverberation performance Noise suppression – nulls diffuse noise sources (air conditioning, road noise etc.) to enable accurate, consistent voice capture Automatic gain control (AGC) – ensures a consistent far-end volume for speakers at different distances from the device. Beyond the specialised microphone interface and two supporting linear mic arrays, the XVF3800 also inco...
