Abstract

An apparatus for decoding a signal and method thereof are disclosed, by which the audio signal can be controlled in a manner of changing/giving spatial characteristics (e.g., listener's virtual position, virtual position of a specific source) of the audio signal. The present invention includes receiving an object parameter; extracting object information by parsing the received object parameter; generating a control parameter using the extracted object information and control information including at least one of user control information, default control information, device control information, and device information; and, generating a rendering parameter determining a position and level of an object in an output signal using the object parameter and the control parameter.
