    Abstract: The present invention relates to a method and an apparatus for generating an additional information bit stream of a multi-object audio signal. The apparatus for generating an additional information bit stream of a multi-object audio signal according to the present invention includes a spatial cue information input unit for taking, as an input, spatial cue information generated from a multi-object audio signal encoding device, a preset information input unit for taking, as an input, preset information for a multi-object audio signal, and an additional information bit stream generating unit for generating an additional information bit stream by using the spatial cue information and the preset information. The additional information bit stream includes a header region and a frame region. The preset information is included in the frame region. The apparatus of the present invention is advantageous as it is capable of changing set audio scene information in accordance with the idea of an editor or a sound engineer even during reproduction of a multi-object audio signal because preset information is included in the frame region of the additional information bit stream generated during encoding of the multi-object audio signal.
