Abstract
An audio system includes an automatic level controller receiving at least one input audio signal from at least one audio medium. The automatic level controller includes a gain adjust module for producing an output audio signal based on the at least one input audio signal. A difference between a maximum sound level and a minimum sound level of the at least one input audio signal is greater than a difference between a maximum sound level and a minimum sound level of the output audio signal. A filter arrangement is communicatively coupled to the automatic level controller. The filter arrangement receives the output audio signal and divides the output signal into a plurality of filtered signals. Each of the filtered signals corresponds to a respective frequency band. A multiband dynamics controller is communicatively coupled to the filter arrangement. The multiband dynamics controller receives the filtered signals and applies a different respective gain characteristic to each of the filtered signals to thereby produce a plurality of gain adjust signals. The gain adjust signals are combined into a multiband dynamics controller output signal.
