ClearOne gets patent on echo cancellation

ClearOne (NASDAQ: CLRO), a global provider of audio and visual communication solutions, has been awarded a new patent on a system and method for combining echo cancellation and beamforming microphone arrays, the company said.

This patented technology is one of many innovations that help ClearOne conferencing systems to provide the best, clearest, and most intelligible audio possible.

On April 25, 2017, the US Patent and Trademark Office (USPTO) issued United States Patent number 9,635,186 entitled “A Conferencing Apparatus that combines a Beamforming Microphone Array with an Acoustic Echo Canceller.”

The ´186 patent covers, among other things, the method of first using a beamforming algorithm to generate several fixed beams, followed by performing acoustic echo cancellation on each beam, selecting a beam for transmission, and inhibiting the system from switching beams when the remote party speaks. Without this protection, whenever the remote party speaks they may hear noise fluctuations, distortions, and/or ambient sound changes that detract from conference quality and clarity.

This new patent is part of ClearOne´s growing patent portfolio that currently includes over 100 patents and pending patent applications covering multiple new technologies in the fields of audio and video processing, audio and video streaming, and communication technologies. This ongoing development of new patents continues ClearOne´s market leadership position, strong history of product innovation, and development of cutting-edge technologies.

ClearOne is a global company that designs, develops and sells conferencing, collaboration, and network streaming & signage solutions for voice and visual communications. The performance and simplicity of its advanced, comprehensive solutions offer unprecedented levels of functionality, reliability, and scalability.
