摘要： A method of tracking sound sources in an environment by monitoring the local area with a primary sensor system comprising a microphone array. The location of sound sources in the local area are tracked using the monitored sound. If an ambiguity is determined in the tracked location of the sound source, a secondary sensor system is activated. The secondary sensor system has a larger power draw than the primary sensor system. The secondary sensor system determines the updated location of the sound source. The tracked location of the sound sources is updated to be the updated location. Once the location is updated, the secondary sensor system is deactivated.

摘要： A method to combine contact and acoustic microphones in a headset for voice wake and voice processing in immersive reality applications is provided. The method includes receiving, from a contact microphone, a first acoustic signal, determining a fidelity and a quality of the first acoustic signal, receiving, from an acoustic microphone, a second acoustic signal, and when the fidelity and quality of the first acoustic signal exceeds a pre-selected threshold, combining the first acoustic signal and the second acoustic signal to provide an enhanced acoustic signal to a smart glass user. A non-transitory, computer-readable medium storing instructions to cause a headset to perform the above method, and the headset, are also provided.

摘要： A system controls the audio focus for a user in a virtual conference call. The system retrieves sound parameters associated with participants in the virtual conference call with the user from a user profile of the user. The sound parameters define volume adjustments to be applied to audio data received from the participants for generating an audio mix customized to the user. The system receives the audio data from client devices of the participants, and for each of the participants, adjusts the audio data of the participant using the associated sound parameter of the participant. The system adds the adjusted audio data of the participants to the audio mix for the user and provides the audio mix to a client device of the user.

摘要： Determination of a set of acoustic parameters for a headset is presented herein. The set of acoustic parameters can be determined based on a virtual model of physical locations stored at a mapping server. The virtual model describes a plurality of spaces and acoustic properties of those spaces, wherein the location in the virtual model corresponds to a physical location of the headset. A location in the virtual model for the headset is determined based on information describing at least a portion of the local area received from the headset. The set of acoustic parameters associated with the physical location of the headset is determined based in part on the determined location in the virtual model and any acoustic parameters associated with the determined location. The headset presents audio content using the set of acoustic parameters received from the mapping server.

摘要： The disclosed computer-implemented method may include receiving, from a third party, a portion of data or computer-executable logic that is part of a specified model. Each model may include various portions of independently verifiable computer-executable logic. The method may further include receiving data at a processing engine. The processing engine may be configured to apply the specified model to the received data. The method may then execute the specified model at the processing engine to modify the received data and send the modified data to an application that is configured to process the modified data. Various other methods, systems, and computer-readable media are also disclosed.

摘要： This disclosure describes embodiments of methods, non-transitory computer-readable media, and systems for detecting that a physical space includes a physical object corresponding to an analogous virtual object from an augmented reality experience and rendering (or otherwise modifying) the augment reality experience to integrate the physical object as part of the experience. In particular, the disclosed systems can determine that a physical object within a physical environment corresponds to an analogous virtual object of an augmented reality experience. Based on this correspondence, the disclosed systems can modify one or more of the virtual graphics, sound, or other features corresponding to the augmented reality experience to represent the virtual object using the physical object. For example, the disclosed systems can modify acoustic features of a sound for the augmented reality experience to simulate the sound originating from (or being affected by) the physical object.

摘要： A communication system provides audio content to one or more client devices capable of playing spatialized audio content. For example, the communication system receives audio content from a client device and transmits the audio content to other client devices to be played for users. The communication system dynamically modifies audio content transmitted to different client devices based on a payload including audio parameters (e.g., local area acoustic properties, an audiogram for a user, a head related transfer function for a user, etc.) received from a client device.

摘要： A system receives audio data in a frequency range of 20 Hz-20 kHz. The received audio data is encoded by the system into ultrasonic data in frequencies that are greater than 20 kHz, and transmitted into a local area that is proximal to the transmitting device, i.e., within the transmission range of the transmitting device. An ultrasonic communication device that is located in the transmission range of the transmitting device may receive the ultrasonic data. The received ultrasonic data is decoded by the ultrasonic communication system in the receiving device into audio data in a frequency range of 20 Hz-20 kHz, and subsequently presented to a user of the receiving ultrasonic communication device.
