Patent number: 9426279Abstract: Traditionally, echo cancellation has employed linear adaptive filters to cancel echoes in a two way communication system. The rate of adaptation is often dynamic and varies over time. Disclosed are novel rates of adaptation that perform well in the presence of background noise, during double talk and with echo path changes. Additionally, the echo or residual echo can further be suppressed with non-linear processing performed using joint frequency-time domain processing.Type: GrantFiled: January 21, 2014Date of Patent: August 23, 2016Assignee: CONEXANT SYSTEMS, INC.Inventors: Youhong Lu, Trausti Thormundsson, Yair Kerner, Ragnar H.

Patent number: 8983092Abstract: Peak reduction and power limitations are used to prevent distortion and protect components. In a cellular telephone, peak reduction can be based on battery power level to prevent electrical distortion from saturation. In addition peak reduction can be used to prevent mechanical distortion such as rub and buzz. Dynamic range compression can be used for peak reduction. In another application dynamic range compression can be used to control the power output to protect a speaker from damage. One example of a dynamic range compressor/peak limiter comprises a look-ahead buffer and an analysis engine. For example, the look-ahead buffer holds a window of samples of a signal. The analysis engine selects a gain envelope function on the basis of the samples, for example, by selecting the Pth sample in the buffer whenever that sample exceeds a given threshold.Type: GrantFiled: July 14, 2011Date of Patent: March 17, 2015Assignee: Conexant Systems, Inc.Inventors: Trausti Thormundsson, Govind Kannan, Shlomi I.

Patent number: 8656415Abstract: There is provided a method for use in a computer for redirecting an audio stream from a first audio endpoint to a second audio endpoint in the computer having a controller and a computer operating system for execution by the controller. The method includes directing the audio stream from a client application running on the computer operating system through a first audio resource stack of the computer to the first audio endpoint. The method further includes creating an audio endpoint bridge using the computer operating system, where the audio endpoint bridge provides a path for the audio stream to be directed from the first audio resource stack to pass through a second audio resource stack to the second audio endpoint. The method may also enhance the audio stream to reduce noise and redirect the audio stream to the second audio endpoint using the audio endpoint bridge.Type: GrantFiled: June 30, 2008Date of Patent: February 18, 2014Assignee: Conexant Systems, Inc.Inventors: James W.

Patent number: 8411847Abstract: Disclosed methods and systems measure acoustic responses to training signals activated prior to communication sessions. Profiles related to the acoustic responses are saved and adapted during communication sessions. Training signals may have uniform frequency distributions over a frequency range and may be in response to user inputs, timeouts, or predetermined events. In the next excessive divergence is detected, an adapted profile may be substituted by an original, trained profile.Type: GrantFiled: June 10, 2008Date of Patent: April 2, 2013Assignee: Conexant Systems, Inc.Inventors: Bryan J.
