A residual encoding device comprises: a down-mix signal generating unit for generating a down-mix signal by finding a weighted sum of a plurality of object signals which are inputted; a special parameter generating unit for generating a spatial parameter by normalizing a sub-band power of each of the plurality of object signals; and a residual signal generating unit for generating a residual signal of each of the plurality of object signals by using the spatial parameter. |
