The XVF3800 Voice Processor includes microphone interfaces, voice processing, and control functions, allowing you to optimize voice performance fully according to the acoustic characteristics of specific products. - Acoustic Echo Cancellation (AEC) AEC eliminates echo from microphone audio input, while reducing remote echoes, allowing the XVF3800 to extract clear voice signals even with high volume speaker outputs. - Noise Suppression Noise suppression eliminates static and non-static diffuse noise sources, such as air conditioning and road noise, with frequency characteristics that remain constant over time. This makes accurate, consistent voice capture possible. - Adaptive Multi-Beam Former Free-running and beamforming focused on tracking static and non-static speech sources, identifying Direction of Arrival (DoA), and isolating interesting speech to enhance bidirectional call and reverberation removal performance. - Automatic Gain Control (AGC) Configurable AGC adjusts output channels for optimal voice communication effects. Ideal for Teams and Zoom certification.
