PROBLEM TO BE SOLVED: To provide a power management system for an audio system.SOLUTION: The audio power management system includes: a parameter computer configured to perform calculation of an estimated operational characteristic of a loudspeaker in real-time based on a measured actual parameter of an audio signal driving the loudspeaker; a threshold comparator in communication with the parameter computer, the threshold comparator being configured to develop and monitor a threshold in real-time based on the measured actual parameter and the estimated operational characteristic; and a limiter in communication with threshold comparator, the limiter being positioned between an audio source supplying the audio signal and the loudspeaker in receipt of the audio signal, the limiter being configured to selectively adjust the audio signal in real-time based on the threshold. |
