    摘要: Provided are an apparatus and method for coding and decoding a multi object audio signal with multi channel. The apparatus includes: a multi channel encoding means for down-mixing an audio signal including a plurality of channels, generating a spatial cue for the audio signal including the plurality of channels, and generating first rendering information including the generated spatial cue; and a multi object encoding unit for down-mixing an audio signal including a plurality of objects, which includes the down-mixed signal from the multi channel encoding unit, generating a spatial cue for the audio signal including the plurality of objects, and generating second rendering information including the generated spatial cue, wherein the multichannel encoding unit generates a spatial cue for the audio signal including the plurality of objects regardless of a Coder-Decoder (CODEC) scheme the limits the multi channel encoding unit.

    摘要: Provided is a method and apparatus for decoding a multi-object audio signal. The apparatus comprises: a side information bitstream input unit configured to receive the side information bitstream; a spatial cue information extractor configured to extract spatial cue information based on the side information bitstream; a preset information extractor configured to extract preset information and default preset information based on the side information bitstream; and a decoder configured to decode the multi-object audio signal using at least one of the spatial cue information, the preset information and the default preset information. The side information bitstream includes a header region and a frame region. The frame region includes the preset information and the header region includes the default preset information for using at least one of the preset information and the default preset information for rendering the multi-object audio signal corresponding to the frame region. The preset information includes a layout of a playback system to be a mono system, a stereo system or a multi-channel system, an audio object location and an audio object level.
