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: A display system includes a head-mounted display unit and a detachable speaker unit. The head-mounted display unit outputs visual content to a user and provides a visual pass-through of a real environment to the user. The detachable speaker unit is detachably coupleable to the head-mounted display unit for providing aural content to the user. At least one of the visual content or the aural content is changed according to a position of the detachable speaker unit relative to the head-mounted display unit.

Abstract: Methods and apparatus for communicating audio packets with ultra-low latency at high data rates from an audio source device to one or more audio output devices over a wireless personal area network (WPAN) connection, such as via a Bluetooth connection. Latency is reduced by using time-efficient audio coding and decoding, limited retransmissions, reduced time and frequency of acknowledgements, and by combining Bluetooth Classic (BTC) packets for downlink audio and downlink control with Bluetooth Low Energy (BTLE) packets for uplink control, uplink acknowledgements, and inter-device wireless communication. The number of retransmissions and packet concealments per frame cycle can be limited to an upper threshold number to satisfy a low latency requirement.

Abstract: An audio communication system which enables two-way audio communication between at least two users in separate locations includes a talker feedback system which commands a set of audio drivers to generate an acoustical feedback signal which includes at least a portion of an audio input received from the talker to be directed to the talker. The acoustical feedback signal can be generated in response to an intensity of the talker-generated acoustical signal meeting a threshold level, and the feedback can result in causing the talker to reduce the intensity of the talker-generated audio content. The acoustical feedback signal can be directed to a limited portion of the environment in which the talker is located. The talker feedback system can provide at least some of the feedback to the talker via a haptic feedback device.

Abstract: A distributed self-scaling network audio processing system includes end nodes interconnected by packet-switched network and operating as peers on the network. Each of the end nodes supports local input processing, mixing, and output processing. The input processing includes the option of dual input channels for supporting separate front-of-house and monitor workflows. End nodes are added to the system to support specific audio processing applications, based on the number of audio sources, the number of output mixes required, and the number of locations from which users choose to interact with the system.

Abstract: An audio signal source balancing adapter provides connection between an unbalanced audio source and a balanced input amplifier of an audio processing instrument, such as an audio mixer panel, with a variable resistor in the cold line, so the input impedance may be matched by adjusting the variable resistor until "hum" disappears at the audio processing instrument. In one embodiment the balancing adapter has a mono plug at one end of a shielded cable and a stereo plug at the other, with a variable resistor, such as a rotary potentiometer, mounted in a housing at the mono plug. In another embodiment, a single housing has a mono plug in one wall of the housing and an XLR connector in another, with a rotary potentiometer within the housing, and wired to provide a balancing impedance in the cold line between the connectors.

Abstract: A digital audio gain control system has an operator interface with a CPU, RAM storage, and input devices for a user to store transfer characteristics relating gain to be applied to an incoming audio signal to the signal strength of that incoming signal. A communication link allows the transfer characteristic function to be sent to a RAM in a separate patchable amplifier unit having a DSP and RAM, and level detection circuitry for monitoring the signal strength of an incoming audio signal and applying gain according to the transfer characteristic communicated to the on-board RAM. The amplifier unit also sends operating information back to the operator interface, where operation may be displayed to aid an operator in adjusting the function.

Abstract: A production mix controller for processing and mixing audio signals has a control console separate from an audio mainframe. All audio signals to be mixed are confined to the audio mainframe, and the control console has channels of input devices providing low-voltage input control signals, which are converted to digital signals and stored by a microprocessor-based control system. The control system includes menu selectable functions for setting control modes and routing signals. Digitally controlled analog audio control devices at the audio mainframe are controlled by digital signals retrieved from memory and communicated to the audio mainframe, making the system software controllable. The invention includes functions for block copying arrays of input settings, and facility for storing and retrieving digital snapshots of entire configurations. Input controls are arrayed in channels, and channels are arranged in removable pod modules for modularity.
