VOLUME AUTOMATIC CORRECTION DEVICE BY CHANNEL CHANGE AND ITS METHOD

摘要

PROBLEM TO BE SOLVED: To provide a volume automatic correction device by channel change and its method. SOLUTION: The method comprises a process of comparing an average level value of an input audio signal and a preset input/output level curve and generating a gain value for adjusting the level of the audio signal; a process of adjusting the volume of the input audio signal by reflecting the generated gain value on the level of the input audio signal; and a process of adjusting a dynamic range for an audio signal of which the volume is adjusted.
