Abstract

An apparatus for processing an audio signal and method thereof are disclosed. The present invention includes receiving the audio signal and preset information; obtaining preset matrix from the preset information, wherein the preset matrix indicates contribution degree of the object to output channel; and adjusting output level of the object by using the preset matrix. Accordingly, without user's setting for each object, if preset metadata to be applied to an audio signal is selected with reference to previously- set preset metadata, levels of objects included in the audio signal can be easily adjusted using preset rendering data corresponding to the selected preset metadata.
