摘要： Aspects of the disclosure relate to personal stage monitoring (PSM) systems and methods. A PSM system may include a transmitter and a receiver, where the transmitter may transmit audio data to the receiver to provide performers with monitoring feedback. The PSM transmitter may include audio processing and/or personal mixing devices that provide a customized mix of audio signals that may be transmitted to the receiver. The integration of the audio processing and/or mixing devices with the PSM transmitter advantageously reduces the complexity of the overall audio system and improves audio quality and performance by reducing noise and latency of the audio system.

摘要： A microphone module comprises a housing, an audio bus, and a first plurality of microphones in communication with the audio bus. The microphone module further comprises a module processor in communication with the first plurality of microphones and the audio bus. The module processor is configured to detect the presence of an array processor in communication with the audio bus, detect the presence of a second microphone module in communication with the audio bus, and configure the audio bus to pass audio signals from both the first plurality of microphones and the second microphone module to the array processor.

摘要： Systems and methods are described herein for receiving, at a plurality of audio channels, respective audio signals captured by one or more microphones; based on a speech quality determination for each signal, identifying, in real time, a first subset of the audio channels as capturing speech audio, and a second subset of the audio channels as capturing noise audio, wherein the first subset comprises one or more audio channels and the second subset comprises one or more other audio channels; generating, using a first mixer, a mixed audio output that includes the signals received at the one or more audio channels; generating, using a second mixer, a noise mix that includes the signals received at the one or more other audio channels; and removing off-axis noise from the mixed audio output by applying, to that output, a mask determined based on the noise mix.

摘要： A wireless communication system with scalable diversity and multi-transceiver diversity deployment is disclosed. An example communication system includes a first wireless transceiver, having a first bandwidth and a first center frequency, a second transceiver, having a second bandwidth and a second center frequency, and a processor. The processor is configured to operate the wireless communication system in a first mode when a difference between the first center frequency and the second center frequency is greater than or equal to half of the first bandwidth plus the second bandwidth. The processor is also configured to operate the wireless communication system in a second mode when a difference between the first center frequency and the second center frequency is less than half of the first bandwidth plus the second bandwidth.

摘要： A printed circuit board (PCB) assembly supports selecting alternate printed antenna geometries of an antenna by selectively placing common PCB components (for example, zero-ohm resistors) on the PCB. The desired zero-ohm resistors may be placed using automated part placement equipment commonly used to place surface mount components. The configurable antenna comprises at least one antenna section having a plurality of antenna components. Zero-ohm resistors are selectively placed in series along the antenna section to couple the desired conductor components when manufacturing the PCB assembly. With some embodiments, a configurable antenna includes a low frequency antenna section that may be selectively coupled with a high frequency antenna section antenna through one or more zero-ohm resistors, where each antenna section has a plurality of antenna components. With this approach, a common printed circuit board may be used to support a plurality of antenna variations spanning different frequency bands.

摘要： A microphone device comprising, for example, a mid microphone cartridge and two side microphone cartridges. The mid microphone cartridge may be, for example, a cardioid microphone cartridge, and the side microphone cartridges may each be, for example, a bidirectional microphone cartridge. Each of the mid microphone cartridge and of the two side microphone cartridges may be orthogonal to the other two microphone cartridges. The microphone device, which may be referred to herein as a mid dual-side microphone, may provide a combined pickup pattern, such as a beam and/or a toroid, that may be steerable.

摘要： A microphone may digitize multiple analog audio channels into multiple digital audio channels, digitally process the digital audio channels, and output the digital audio channels to another device while maintaining channel separation. The microphone may also include a touch-sensitive user interface that may have multiple live meter modes and a user-selectable color theme.
