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: Address range memory mirroring in a computer system, and related methods and computer-readable media. The computer system includes one or more memory mirror agents that are each configured to be programmed to mirror write data of a write request to a memory address mapped to the memory mirror agent. The memory mirror agent is configured to mirror write data to a redundant memory space in memory if the write memory address is within a programmed memory space to be mirrored by the memory mirror agent. The memory mirror agent can be programmed to perform memory mirroring based on specific address ranges to provide flexibility in controlling and changing the exact memory space of the memory system to be mirrored. If an error is detected in read data in response to a memory read request, the memory mirror agent can retrieve the stored redundant data to maintain data integrity.

Abstract: 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.
