VOLUME LEVELER CONTROLLER AND CONTROLLING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a volume leveler controller and a controlling method.SOLUTION: In one embodiment, a volume leveler controller includes an audio content classifier for identifying a content type of an audio signal in real time; and an adjusting unit for adjusting a volume leveler in a continuous manner on the basis of the identified content type. The adjusting unit may configured to positively correlate dynamic gain of the volume leveler with informative content types of the audio signal, and negatively correlate the dynamic gain of the volume leveler with interfering content types of the audio signal.SELECTED DRAWING: Figure 20
