Keyboard Click Removal (KRC) software is designed to suppress the impulsive clicking noise generated by keyboards or mice. When a participant of conference is taking notes on their laptop or messaging other participants, their keyboard clicks can be heard by all remote users. This creates a distracting and difficult listening environment. The KRC software is designed to solve this common problem.

VOCAL’s Keyboard Click Removal software is a real-time Voice Quality Enhancement (VQE) algorithm for voice communications. The algorithm works solely on the microphone capture stream, no peripheral keyboard information is required. When the clicks are detected, the clicks are smoothly suppressed for an improved listening experience. The KRC software can be offered as a standalone solution or can it into integrated into VOCAL’s Acoustic Echo Cancellation and Noise Reduction module.
