  • Patent number: 8078298
    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.

  • Patent number: 8054993
    Abstract: A system for boosting the bass of an audio signal to closely match or mirrors a plurality of Robinson-Dadson loudness curves by interpolating coefficients from a table of values representing the Robinson-Dadson loudness. The system having a controller that interpolates the coefficients from the loudness curves and then uses the coefficients in a shelf filter that makes adjustments to the audio signal. The result of the adjustments to the audio signal is the introduction of bass boost slowly through a diminuendo or lowering of level through volume adjustment and to removes the bass boost rapidly during a crescendo or increase in level through user volume adjustment.

  • Patent number: 7742606
    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.

  • Patent number: 7725826
    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.

  • Patent number: 7689305
    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.
