VocalFusion voice processor for conference calling

Our high-performance digital signal processing solutions make the quietest voice in the room stand out and remove unwanted background noise to deliver outstanding sound performance. Our mono-AEC voice processor gives you up-close voice capture and processing accuracy at far-field range – even in noisy environments. Ideal if you’re looking for a cleaner, sharper conference call sound.


Accurate voice capture and barge-in from across the room, from across the room and for even the quietest of voices.


Mono-acoustic echo cancellation, noise suppression and dereverberation cut unwanted noise and echo for clear sound capture


Beamforming tracks the speaker of interest so you get best in class performance at all angles and over long distances.

Our rich optimisation parameters for the XVF3100 voice processor lets you adjust for noise attenuation, gain control and residual echo so you can tailor the best voice capture performance for your product. And our engineers are on hand to help you move rapidly from prototype to tuning, and from testing to volume production with a world-class product.
