Abstract
This paper presents a rule-based algorithm for designing a smart volume controller used in TVs. The algorithm is able to detect variations of loudness coming from different audio sources, i.e., TV programs and commercials, and adjust the volume controller intelligently so that the maximum allowable loudness is kept while maintaining the dynamic range of the programs. The design has been implemented and tested. Experimental results show the effectiveness of this design.
