Abstract: A system for management and control of audio-related equipment. A link manager may be included in the system. The link manager may be configured to manage subscriptions to multiple other audio-related devices or control panel views. When the managed data variables change, the link manager module may notify other audio-related devices and/or control panel views of the change. In response to the notification, the other audio-related devices and/or control panels may subscribe to the audio-related device with the changed data variable, to request receipt of the updated data variable. In some examples, the link manager module may also be configured to lessen the subscription burden for a particular audio-related device.

Abstract: A system for management and control of audio related equipment. The system provides an architecture to manage, monitor, and control all of the audio related equipment in an audio system. A communication protocol used within the system allows standardized communication between the performance equipment mangers and the audio related devices, as well as device-to-device communication. The protocol allows users to add audio related devices to an audio system without performing a setup to configure communication between the devices.

Abstract: A system for determination of the functionality of an audio-related device that is operable in an audio system includes a performance equipment manager. The performance equipment manager may receive from an audio-related device an audio node structure representative of the corresponding audio-related device. The received audio node structure may be reviewed to determine if all the components included in the audio node structure are predefined within the performance equipment manager. For those components that are known, no discovery is necessary and actual values of changeable parameters in the audio-related device may be obtained. For unknown components of the audio node structure, the performance equipment manager may undertake discovery to identify additional portions of the audio node structure, and/or attributes related to the unknown components, in order to obtain actual values of changeable parameters related to the unknown components.

Abstract: A system includes a variable amplifier, a source sound processor, an area sound processor, and an adjustment circuit. The variable amplifier adjusts an audio input signal to generate an audio output signal with an appropriate level so that the audio output signal is audible over noise in a listening area. The source sound processor and the area sound processor may split the audio output signal and a monitoring signal into frequency bands, and may compare these signals band-by-band to find differences that represent time-varying noise in the monitoring signal. These differences may be modified to account for the acoustic response of the listening area and for constant-level background noise in the listening area. The adjustment circuit controls the variable amplifier in response to these differences.

Abstract: A system for management and control of audio-related equipment. The system is a common architecture that provides the capability to manage, monitor and control all of the audio-related equipment in an audio system. To facilitate messaging between audio-related devices, each of the audio-related devices may be assigned a node ID a sequential manner as each audio-related device powers up. The system may also include a method for discovery of audio-related devices on an audio network. In some examples, a PEM may be located geographically remote from the audio-related devices. Accordingly, error logging, alarming and system operation may be monitored to provide troubleshooting from a remote location.

Abstract: A system may instantiate a control panel view that is useable to monitor and control an audio-related device operable in an audio system. A product plugin that corresponds to an audio-related device may receive and analyze the components of an audio node structure received from the audio-related device. The product plugin is configured to store one or more predefined control panel views that are associated with one or more of the components. The product plugin is also configured to instantiate the predefined control panel views that correspond to the components. If the product plugin determines that all of the components are not represented, one or more user interface aspects can be integrated into one or more of the control panel views prior to instantiation. Alternatively, a generic control panel view can be generated.

Abstract: A system for communication among audio-related devices in an audio system includes a performance equipment manager that communicates with audio-related devices to monitor and control changeable parameters of a corresponding audio-related device. Each of the audio-related devices includes an audio node structure having components that are representative of the functionality of the respective audio-related device. Some of the components are representative of changeable parameters in the audio-related device. The performance equipment manager is configured to be selectively subscribed to one or more of the changeable parameters so that when a predefined condition occurs, the audio-related device is configured to automatically provide the current value of the changeable parameter(s) to the performance equipment manager.

Abstract: Systems and methods for ambient noise compensation are disclosed. One example of a system includes a variable amplifier, a source sound processor, an area sound processor, and an adjustment circuit. The variable amplifier adjusts an audio input signal to generate an audio output signal with an appropriate level so that the audio output signal is audible over noise in a listening area. The source sound processor and the area sound processor may split the audio output signal and a monitoring signal into frequency bands, and may compare these signals band-by band to find differences that represent time-varying noise in the monitoring signal. These differences may be modified to account for the acoustic response of the listening area and for constant-level background noise in the listening area. The adjustment circuit controls the variable amplifier in response to these differences.
