The method is applicable to a head-mounted device having a motion sensor, a left speaker, and a right speaker and includes the following steps. A rotation angle of the head-mounted device is detected by the motion sensor. Dual-channel audio signals corresponding to the left and right speakers are obtained.

Energy distributions of the four-channel audio signals of the left and right speakers are corrected according to the rotation angle and the four acoustic source positions to respectively generate a left output signal and a right output signal.

Abstract: An exemplary acoustics generation system accesses time-domain audio data representative of a virtual sound presented to an avatar of a user experiencing an extended reality world, and transforms the time-domain audio data into frequency-domain audio data representative of the virtual sound. The system also accesses acoustic propagation data representative of characteristics affecting propagation of the virtual sound to the avatar within the extended reality world. Based on the frequency-domain audio data and acoustic propagation data, the system generates a frequency-domain binaural audio signal representative of the virtual sound as experienced by the avatar when the propagation of the virtual sound to the avatar is simulated in accordance with the characteristics affecting the propagation. Additionally, the system transforms the frequency-domain binaural audio signal into a time-domain binaural audio signal configured for presentation to the user as the user experiences the extended reality world.

Abstract: An audio assembly includes a microphone assembly, a controller, and a speaker assembly. The microphone assembly detects audio signals. The detected audio signals originate from audio sources located within a local area. Each audio source is associated with a respective beamforming filter. The controller determines beamformed data using the beamforming filters associated with each audio source and a relative contribution of each of the audio sources using the beamformed data. The controller generates updated beamforming filters for each of the audio sources based in part on the relative acoustic contribution of the audio source, a current location of the audio source, and a transfer function associated with audio signals produced by the audio source. The controller generates updated beamformed data using the updated beamforming filters and performs an action (e.g., via the speaker assembly) based in part on the updated beamformed data.

A relative position of the wireless loudspeaker is determined when sound from the wireless loudspeaker is determined to be the dominant sound (e.g., during output of a response to a user command or query or during speech by a far-side party during a two-way audio communication). A beam corresponding to the relative position is thereby selected for echo cancellation.
