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.

Abstract: An electronic device includes sensors configured to detect an orientation of a display, driver logic, and a speaker array. The driver logic processes the audio data received by an interface to form audio output data, and forms driver signals representing the audio output data based on the orientation of the display detected by the one or more sensors. The speaker array receives the driver signals formed orientation of the display, and renders the audio output data for playback based on the driver signals.

Abstract: An electronic device includes a microphone array configured to capture audio data, one or more sensors configured to detect an orientation of the microphone array, and digital signal processing (DSP) logic, and an interface. The DSP logic processes, based on the orientation of the microphone array detected by the one or more sensors, the audio data captured by the microphone array to form audio input data. The interface configured to transmit the audio input data over a communications channel to be output by another electronic device.
