Our range of algorithms help reduce background noise by up to 20 dB and thus provides significant speech enhancement in a wide area of intercom applications.

Our algorithm works on the data arriving from a single input channel, calculates statistical features of the data stream and based on these features, distinguishes between components of speech and noise. The algorithm preserves the speech components and attenuates the noise energy significantly. It combines maximum noise attenuation with minimal distortion of the speech signal.

Our ANC technology can be utilised effectively in applications where varying background noise requires suppressing e.g call centres, handsets and inter communication systems.
