Abstract: Systems and methods for acoustic echo cancellation with wireless microphone and speaker systems are described herein. In one embodiment, an acoustic echo canceller is provided that can, among other things, cancel an acoustic echo component of an audio signal that is produced when an audio signal transmitted to a remote speaker on a lossy wireless link is picked up by a remote microphone and transmitted back to a base station on a lossy wireless link.

Abstract: A video conferencing system has a microphone array that operates to receive acoustic signals corresponding to voice activity and to determine that the signals are either from within a sound field of interest and from outside the sound field of interest, and if the signals are from outside the sound field of interest the system attenuates these signals by not steering a microphone array beam towards these signals.

CPC classification number: H04W56/0015 , H04W48/16 , H04W88/08
Abstract: Systems and methods for adaptive OTA (over-the-air) synchronization of RF (radio frequency) base stations are described herein. Using these systems and methods, base stations in wireless audio systems can automatically identify externally sourced base station clocks and merge overlapping clock system domains, thereby eliminating the need for complex base station management and network configuration.

Abstract: A digital audio conferencing system has a fixed base station that is in communication with a far end (R.E.) system over a communication network. The base station is associated with a wireless loudspeaker and one or more wireless microphones. The base station operates to receive F.E. audio signals to be played by the wireless loudspeaker, and it operates to remove acoustic echo picked up by the wireless microphones. A first clock controlling F.E. audio signal sampling at the base station, and a second clock controlling audio signal sampling and at a wireless microphone are synchronized to one master, reference clock that controls the operation of the base station. Acoustic echo included in an audio signal picked up by a wireless microphone is removed by AEC functionality running in the base station.

Abstract: An audio or video conferencing system having an array comprised of two or more microphones and having one or more loudspeakers positioned proximate to the microphones. The conferencing system also has acoustic echo cancellation (AEC) functionality that removes direct and reverberant acoustic echo from microphone signals in two separate acoustic echo cancellation operations. The first AEC operation removes direct acoustic echo prior to a beamforming operation, and the second AEC operation removes reverberant acoustic echo from a microphone signal subsequent to the beamforming operation.
