    摘要： 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.

    摘要： 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.

    摘要： 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.

    摘要： An ambient noise compensation system determines an ambient noise level of a listening area. The ambient noise level may be calculated from the differences between a desired audio signal in the listening area, a measured background noise level in the listening area, and measured acoustic characteristics of the listening area. Based on the ambient noise level, the system adjusts a level of the desired audio signal so that it is audible over undesirable noise.

    摘要： A ring based network includes a first circuit and a second circuit. The first circuit selects one of a number of inputs and switches an input to a first common communication line. A second circuit selects one of a second number of inputs and switches a second input to a second common communication line linked to one of the first number of inputs. A detect circuit controls the switches of the first and second circuit to emulate a communication ring in which nodes are connected in series in a communication loop.
