Abstract
An apparatus for controlling a volume of an audio signal and method thereof are disclosed, by which a volume of an input signal can be controlled by using a non-linear gain curve and a target volume of the input signal. The present invention includes receiving an input signal and reference information controlling a volume of the input signal; and adjusting a volume of the input signal with the reference information, wherein the reference information comprises at least one of metadata indicating characteristics of the input signal, output environment information indicating characteristics of an environment in proximity to the apparatus and stored reference information being transmitted from memory. Therefore, the present invention is able to control a volume of an input signal adaptively by using reference information, for example metadata, outside environment information and stored reference information.
