Abstract
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.
