Abstract: A personalized (i.e., speaker-derivable) bandwidth extension is provided in which the model used for bandwidth extension is personalized (e.g., tailored) to each specific user. A training phase is performed to generate a bandwidth extension model that is personalized to a user. The model may be subsequently used in a bandwidth extension phase during a phone call involving the user. The bandwidth extension phase, using the personalized bandwidth extension model, will be activated when a higher band (e.g., wideband) is not available and the call is taking place on a lower band (e.g., narrowband).

Abstract: Aspects of the disclosure relate to using a display as a sound emitter and may relate to an electronic device including a display. In particular a vibration sensor such as an accelerometer is physically coupled to the display and senses display vibration to provide a high accuracy feedback loop with respect to representing actual audio output from the display. The electronic device includes an actuator physically coupled to the display and configured to cause vibration of the display in response to an audio signal. The electronic device further includes a vibration sensor physically coupled to the display and configured to output a vibration sensor signal proportional to the vibration of the display due to the actuator. The electronic device further includes a processor operably coupled to the vibration sensor. The processor is configured to adjust the audio signal based on the vibration sensor signal from the vibration sensor.

Abstract: In general, techniques are described for compressing decomposed representations of a sound field. A device comprising a memory and processing circuitry may be configured to perform the techniques. The memory may be configured to store a bitstream representative of scene-based audio data, the scene-based audio data comprising ambisonic coefficients representative of a soundfield. The processing circuitry may be configured to process the bitstream to extract foreground components and corresponding foreground directional information, dequantize the corresponding foreground directional information to obtain corresponding dequantized directional information, and obtain, based on the foreground components and the corresponding dequantized foreground directional information, a reconstructed version of the scene-based audio data.
