Abstract: An audio signal size control method is disclosed. The control method comprises the steps of: calculating, by using an input audio signal, a first band gain for compensating for normalization degradation as a result of normalizing an input audio signal size to a target audio signal size; applying the calculated first band gain to the input audio signal; and normalizing the audio signal, to which the calculated first band gain has been applied.

Abstract: Disclosed is a method whereby a terminal device outputs an audio signal. The audio signal output method comprises the steps of: receiving a broadcast signal including a normalized audio signal having a preset audio signal size; detecting program genre information from the broadcast signal; detecting a preferred audio signal size corresponding to the detected program genre information; and adjusting the size of the normalized audio

Abstract: An audio signal size control method is disclosed. The control method comprises the steps of: measuring a first audio signal size which is the size of the input audio signal; scaling the input audio signal using a preset initial peak weighting value and measuring a second audio signal size which is the size of the scaled audio signal; detecting a third audio signal size by applying the first audio signal size to a preset mapping table for maintaining the sound deviation of the audio signal to be output; and adjusting the size of the input audio signal using the first audio signal size, the second audio signal size, and the third audio signal size.
