Abstract

An electronic device includes a microphone array to capture audio input data, a speaker array to render audio output data for playback; one or more sensors to detect an orientation of the microphone array, acoustic echo cancellation logic, and an interface. The acoustic echo cancellation logic applies acoustic echo cancellation to the audio input data to form echo-cancelled audio input data based on the orientation of the microphone array. The interface transmits the echo-cancelled audio input data over a communications channel as part of an audiovisual communication system.
