Abstract: A head-mounted display system is disclosed that includes a housing; a visual system associated with the housing to facilitate image and/or video display; a wearable support connectable to the housing; and an audio component pivotably connected to the support such that the audio component is movable between a first position in which the audio component is in general alignment with the support, and a second position in which the audio component is out of general alignment with the support. Movement from the first position to the second position transitions the audio component from a first mode (i.e., an extra-aural mode) in which sound is projected through a first port in communication with a driver to a user to a second mode (i.e., an intra-aural mode) in which sound is projected through a second port in communication with the driver to the user.

Abstract: Spatial audio upmixing enables mixing spatial sound on a more granular per-channel level than is possible using conventional upmixing. A spatial bed is a multi-channel audio content that represents a complete sound field description, e.g., a virtual sphere of sound, for example surrounding a simulated reality listener in a simulated reality environment. A new spatial bed is generated by combining sections of at least two of such spatial beds. Other embodiments are also described and claimed.

Abstract: An audio asset library containing audio assets formatted in accordance with a file format for spatial audio includes asset metadata that enables simulated reality (SR) application developers to compose sounds for use in SR applications. The audio assets are formatted to include audio data encoding a sound capable of being composed into a SR application along with asset metadata describing not only how the sound was encoded, but also how a listener in SR environment experiences the sound. A SR developer platform is configured so that developers can compose sound for SR objects using audio assets stored in the audio library, including editing the asset metadata to include transformation parameters that support dynamic transformation of the asset metadata in the SR environment to alter how the SR listener experiences the composed sound. Other embodiments are also described and claimed.

Abstract: A method performed by a first electronic device that includes a first speaker, the method includes, receiving, via a network, a representation of audio content, while a second electronic device is playing back the audio content through a second speaker, determining that the first electronic device is moving away from the second electronic device, and, in response to determining that the first electronic device is moving away from the second electronic device, using the representation of audio to play back the audio content through the first speaker.

Abstract: A method performed by a portable media player device. The method receives a microphone signal that includes audio content output by an audio playback device via a loudspeaker. The method determines identification information regarding the audio content, wherein the identification information is determined through an acoustic signal analysis of the microphone signal. In response to determining that the audio playback device has ceased outputting the audio content, the method retrieves from local memory of the portable media player device or a remote device with which the portable media player device is communicatively coupled, an audio signal that corresponds to the audio content and drives a speaker that is not part of the audio playback device using the audio signal to continue outputting the audio content and any additional audio content related to the audio content.

Abstract: A head-worn device can determine that a playback device is outputting audio content. A microphone of the head-worn device can sense the audio content that is output by the playback device. Spatial filters can be applied to one or more audio channels of additional audio content that compliments the audio content output by the playback device. The resulting spatialized audio can be played through speakers to a user wearing the head-worn device.

Abstract: A method performed by an audio system comprising a headset. The method sends a playback signal containing user-desired audio content to drive a speaker of the headset that is being worn by a user, receives a microphone signal from a microphone that is arranged to capture sounds within an ambient environment in which the user is located, performs a speech detection algorithm upon the microphone signal to detect speech contained therein, in response to a detection of speech, determines that the user intends to engage in a conversation with a person who is located within the ambient environment, and, in response to determining that the user intends to engage in the conversation, adjusts the playback signal based on the user-desired audio content.

Abstract: An audio device can sense sound in a physical environment using a plurality of microphones to generate a plurality of microphone signals. Clean speech can be extracted from microphone signals. Ambience can be extracted from the microphone signals. The clean speech can be encoded at a first compression level. The ambience can be encoded at a second compression level that is higher than the first compression level. Other aspects are also described and claimed.

Abstract: Disclosed are techniques for a multimedia device with audio and video capturing capability to identify an audio device based on acoustic playback signal if the audio device cannot be identified from captured video. The multimedia device may assemble a list of candidate audio devices that are a possible match for the observed audio device from a database of previously recognized audio devices and may transmit commands to the candidate audio devices to play acoustic identification signals. The acoustic identification signals may be audible sound or ultrasonic tone sequences with embedded identification information unique to each audio device. The multimedia device may record and analyze the acoustic identification signals received from any of the candidate audio devices to construct metrics to select the most likely candidate for the observed audio device. The metrics may include time of flight, direction of arrival, received amplitude, direct-to-reverberant ratio (DRR) of the acoustic identification signals.
