An apparatus for processing a media signal and method thereof are disclosed, by which the media signal can be converted to a surround signal by using spatial information of the media signal. The present invention provides a method of processing a signal, the method comprising of generating source mapping information corresponding to each source of multi-sources by using spatial information indicating features between the multi-sources; generating sub-rendering in<img id="CUSTOM-CHARACTER-00001" he="2.46mm" wi="3.13mm" file="US20090003635A1-20090101-P00001.TIF" img-content="character" img-format="tif"/> formation by applying filter information giving a surround effect to the source mapping in<img id="CUSTOM-CHARACTER-00002" he="2.46mm" wi="3.13mm" file="US20090003635A1-20090101-P00001.TIF" img-content="character" img-format="tif"/> formation per the source; generating rendering information for generating a surround signal by integrating the at least one of the sub-rendering information; and generating the surround signal by applying the rendering information to a downmix signal generated by downmixing the multi-sources.
