Abstract: Some examples of the disclosure are directed to systems and methods for dynamically updating simulated source locations of audio sources within spatialized audio content based on detection of a change in the location and/or orientation of an audio output device (e.g., earbuds or speakers that are optionally worn by a user and are optionally included in a headset). In some examples, the simulated source locations are updated if the change in the location and/or orientation of the audio output device is greater than a threshold amount of change, and the simulated source locations are not updated if the change in the location and/or orientation of the audio output device is not greater than the threshold amount of change. In some examples, a simulated source location is identified in a three-dimensional environment. In some examples, a mode of outputting audio is changed in response to movement of an electronic device.

Abstract: A method for using a loudspeaker array that is housed in a loudspeaker cabinet to present audio content to a listener in a room includes receiving (1) an audio channel that includes audio content and (2) acoustical characteristics of the room. The method also produces (1) a first beamformer input signal from the audio channel and (2) a second beamformer input signal and a third beamformer input signal by decorrelating the audio channel and adjusting the audio channel in accordance with the acoustical characteristics of the room. The second and third beamformer input signals are different de-correlated versions of the audio channel. The method also generates driver signals from the first, second, and third beamformer input signals to drive the loudspeaker array to produce a main beam, a first ambient beam, and a second ambient beam, respectively. Other embodiments are also described and claimed.
