Techniques for adaptively providing acoustic echo cancellation (AEC) for a stereo audio signal associated with at least one microphone are discussed herein. Some embodiments may include determining, based at least in part on detecting a reference signal associated with a channel sample portion of the stereo audio signal, a panning state of the stereo audio signal. A hard-panned-configured AEC processing filter or a soft-panned-configured AEC processing filter is applied to the stereo audio signal to generate a filtered audio signal output based on the panning state.

Adaptive acoustic echo cancellation for a stereo audio signal

Array microphone systems and methods that can automatically focus and/or place beamformed lobes in response to detected sound activity are provided. The automatic focus and/or placement of the beamformed lobes can be inhibited based on a remote far end audio signal. The quality of the coverage of audio sources in an environment may be improved by ensuring that beamformed lobes are optimally picking up the audio sources even if they have moved and changed locations.
