Audio or video conferences are often accompanied by room noises, e.g., papers being shuffled, keyboards being tapped, table-tops being tapped, noise from fans, air-conditioning, etc. Although commonly found in various in-room environments, such noises can be annoying and reduce the quality of audio in calls. Techniques of this disclosure reduce noise in microphone pick-up during calls or other in-room recording situations. The techniques utilize optimal placement of microphones, and signal processing techniques such as array processing, speech detection, noise cancellation, etc.
