  • Method and apparatus to automatically control audio volume
    Patent number: 9461603
    Abstract: A method includes comparing a magnitude value of an audio signal in a fixed unit section with a target volume level, measuring audio gain in each fixed unit section using specific functions which are each determined to be different according to a ratio of the target volume level to the audio signal magnitude, and providing the measured audio gain to the audio signal in the fixed unit section.
    Type: Grant
    Filed: September 14, 2012
    Date of Patent: October 4, 2016
    Assignee: SAMSUNG ELECTRONICS CO., LTD.
    Inventor: Chi-ho Chung
