APPARATUS FOR COMPENSATING LOW FREQUENCY BAND AUDIO SIGNAL BASED ON LISTENR'S CHARACTERISTICS

摘要

PURPOSE: An apparatus for compensating a low frequency band audio signal based on listener characteristics is provided to reproduce a high quality of audio signal based on the listening characteristics of a listener. CONSTITUTION: A frequency band division unit(110) divides a frequency band of an audio signal into plural sub-frequency bands, and an auditory characteristic information storage unit(140) stores auditory characteristic information on auditory frequency range of a listener and minimum recognition volume information for an audio signal of each sub frequency band of a listener. A low band compensating unit(150) controls the volume of an audio signal within an auditory frequency range based on auditory characteristic information to be maintained over the minimum recognition volume information.
