METHOD AND APPARATUS FOR CONTROLLING AUDIO SIGNAL LOUDNESS

摘要

Disclosed is a method for controlling the loudness of an audio signal. The method for controlling the loudness of an audio signal comprises: a step of measuring loudness of a first audio signal which is the loudness of an inputted audio signal; a step of scaling the inputted audio signal by using a predetermined initial Peek weight, and measuring loudness of a second audio signal which is the loudness of the scaled audio signal; and a step of controlling the loudness of the inputted audio signal by using the loudness of the first and second audio signals and target audio signal loudness.
