Abstract: The present disclosure relates to an audio system and a method of controlling the same. An aspect of the present disclosure is to provide an optimal listening state according to a user setting volume and hardware characteristics of an audio system. The audio system includes a signal inputter configured to receive an input audio signal; a signal processor configure to variably apply a dynamic range for each area of the input audio signal, to apply a scaling of a size corresponding to an inverse number of a boosting gain determined by a user setting volume for the input audio signal, to perform a tone mapping of the input audio signal by applying the boosting gain, to perform signal compensation for the input audio signal by the inverse number of the scaling, and to apply a master volume according to the user setting volume; a storage configured to store parameters used in signal processing of the signal processor; and a signal outputter configured to output the audio signal processed by the signal processor.

Abstract: A signaling processor is provided. The signaling processor includes a frequency domain processing module configured to generate a cut-off frequency of an input signal and to generate level information for adjusting a level of a high frequency recovery signal and a time domain processing module configured to receive the cut-off frequency and the level information from the frequency domain processing module, to generate a signal having a frequency greater than or equal to the cut-off frequency using part of a signal of a frequency lower than the cut-off frequency in the input signal, to generate the high frequency recovery signal by adjusting a level of the generated signal using the level information, and to synthesize the high frequency recovery signal with the input signal.
