Abstract: An audio system of a client device applies transformations to audio received over a computer network. The transformations (e.g., HRTFs) effect changes in apparent source positions of the received audio, or of segments thereof. Such transformations may be used to achieve “animation” of audio, in which the source positions of the audio or audio segments appear to change over time (e.g., circling around the listener). Additionally, segmentation of audio into distinct semantic audio segments, and application of separate transformations for each audio segment, can be used to intuitively differentiate the different audio segments by causing them to sound as if they emanated from different positions around the listener.

Abstract: A method to assess user condition for wearable devices using electromagnetic sensors is provided. The method includes receiving a signal from an electromagnetic sensor, the signal being indicative of a health condition of a user of a wearable device, selecting a salient attribute from the signal, and determining, based on the salient attribute, the health condition of the user of the wearable device. A non-transitory, computer-readable medium storing instructions which, when executed by a processor, cause a system to perform the above method, and the system, are also provided.

Abstract: A method for providing a world-locked experience to a user of a headset in an immersive reality application includes receiving, from an immersive reality application, a first audio waveform from a first acoustic source to provide to a user of a headset, determining a direction of arrival for the first acoustic source relative to the headset, and providing, to a speaker in the headset, an audio signal including the first audio waveform and intended for an ear of the user of the headset, wherein the audio signal includes a time delay and an amplitude for the first audio waveform based on the direction of arrival for the first acoustic source relative to the user of the headset. A non-transitory, computer-readable medium storing instructions which, when executed by a processor, cause a system to perform the above method, and the system, are also provided.

Abstract: An audio system that includes an IMU or accelerometer in physical proximity to a microphone and a driver. The signal generated by the IMU or accelerometer may be used to filter the audio signal generated by the microphone with respect to mechanically coupling between the driver outputting sound and the microphone via a shared structure. In some cases, an accelerometer may be incorporated into a package of the microphone to provide analog-based filtering prior to converting the audio signal of the microphone to a digital format.
