Abstract: Systems and methods are disclosed for networked audio automixing using array microphones and an aggregator unit that participate in making a common gating decision to determine which channels to gate on and off. Through the use of such a network of array microphones having the capability to generate submix audio signals and reduced bandwidth metrics, as well as AEC processing capability, array microphone lobe selection can be enhanced while maximizing signal-to-noise ratio, increasing intelligibility, and increasing user satisfaction.

Abstract: Array microphone systems and methods that can automatically focus and/or place beamformed lobes in response to detected sound activity are provided. The automatic focus and/or placement of the beamformed lobes can be inhibited based on a remote far end audio signal. The quality of the coverage of audio sources in an environment may be improved by ensuring that beamformed lobes are optimally picking up the audio sources even if they have moved and changed locations.

A front face of the housing includes a sound-permeable screen having a size and shape that is substantially similar to the at least one of the plurality of ceiling tiles. Embodiments also include an array microphone system comprising a plurality of microphones arranged, on a substrate, in a number of concentric, nested rings of varying sizes around a central point of the substrate. Each ring comprises a subset of the plurality of microphones positioned at predetermined intervals along a circumference of the ring.

Abstract: A wireless apparatus (such as a wireless microphone) utilizes an antenna comprising at least one element, which also supports a mechanical feature, an electrical circuit feature, or an ornamental feature. When an element is incorporated into an antenna, the element also continues to support its original feature. Embodiments may support different antenna types, including a half wave dipole and an inverted-F antenna that may be configured at different frequency bands suitable for Bluetooth® and WiFi® services. Embodiments support a wireless microphone that utilizes an antenna comprising a grille assembly and a chassis housing, where the grille assembly and the chassis housing are separated by an electric insulator. The RF output of a transmitter is electrically connected to the grille assembly while a grounding point of the transmitter is electrically connected to the chassis housing.

Abstract: Audio beamforming systems and methods that enable more precise control of lobes and nulls of an array microphone are provided. Optimized beamformer coefficients can be generated to result in beamformed signals associated with one or more lobes steered towards one or more desired sound locations and one or more nulls steered towards one or more undesired sound location. The performance of acoustic echo cancellation can be improved and enhanced.

Abstract: A wireless microphone system utilizes an antenna structure that supports dual frequency bands. With some embodiments, the wireless microphone system comprises a first apparatus (for example, a wireless transmitter) and an attached second apparatus (for example, an attached microphone), where the chassis of the first apparatus and the housing of the second apparatus support the antenna structure through an electrical connector (for example, through an outer shell of a Cannon (XLR) connector) between the two apparatuses. The chassis and the housing may support first and second halves of a dipole antenna, respectively. The first apparatus supports first and second electrical circuits that are operational within a first and second frequency band, respectively, and that connect to first and second input ports of a combining circuit (for example, a diplexer filter). The output port of the combining circuit connects to the housing through the electrical connector.

Abstract: A controller in a wireless system that may switch between two modes. In a first mode, the controller communicates directly with a wireless transceiver, using a first wireless protocol, and receives audio signal directly from the wireless transceiver, using a second wireless protocol. In a second mode, the controller communicates with a wireless transceiver via a wireless access point, using the first wireless protocol, and receives audio signal from the wireless transceiver via a wireless access point, using the second wireless protocol.

Abstract: Described are systems, methods, apparatuses, and computer program products for wireless in-ear-monitoring (IEM) of audio. A system includes transmitter(s) configured to map orthogonal sub-carriers of a digital signal to narrowband receivers to form receiver-allocated audio channels, modulate the digital signal, and transmit the signal as an ultra-high frequency (UHF) analog carrier wave comprising the orthogonal sub-carriers to the nearby receiver. A narrowband receiver is configured to demodulate and sample the sub-carriers allocated to the receiver. Sub-carriers can be positioned orthogonal to one another in adjacent sub-bands of the frequency domain and beacon symbols and pilot signals can be iteratively provided in the same portion of the frequency domain for each channel. The receiver can use non-data-aided and data-aided approaches for synchronization of the time domain and frequency domain waveforms of the received signal to the transmitted signal prior to sampling the allocated sub-carriers.

Abstract: A wireless microphone system may be configured to compensate for a radio frequency (RF) loss incurred in a wired communication path. The system may comprise a receiver configured to receive an downlink RF signal from a wireless microphone, and a transmission line accessory configured to receive an uplink test signal. The RF test signal may be generated from an RF source and may be measured by the transmission line accessory to determine configuration information for an adjustable RF gain circuit.

Abstract: The present disclosure describes a wireless microphone system that allows one or more microphones to wirelessly communicate with a receiver. Additionally, the wireless microphone system may allow for a plurality of microphones to be used interchangeably with the receiver. To ensure communication between the receiver and the one or more microphones, the receiver may occasionally transmit a synchronization signal to the one or more microphones. In response to receiving the synchronization signal, at least one of the one or more microphones may determine that a clock of the at least one microphone is drifting from the master audio clock of the receiver. The at least one microphone may then adjust the microphone's audio clock to re-synchronize the audio clock of the microphone with the master audio clock of the receiver.

Abstract: A microphone assembly can include a microphone capsule having a diaphragm and a diaphragm cover, a grill for protecting the microphone capsule, and a filter material placed between the grill and the diaphragm cover. The microphone assembly can include a first air gap between the grill and the filter material to create a first interface, a second air gap between the filter material and the diaphragm cover to create a second interface, and a third air gap between the diaphragm cover and a diaphragm to create a third interface. The first interface, the second interface, and the third interface are each configured to create turbulence to assist in draining off energy from plosives and wind and reduce intensity of disturbances at the diaphragm. The filter material may include a mesh and can be supported by a frame, and the frame may be configured to fit underneath the grill.
