hierarchical multichannel audio encoding with compact collateral information |
| abstract |
hierarchical multichannel audio coding with compact collateral information. A parametric representation of a multichannel audio signal well describes the spatial properties of the audio signal with compact collateral information when coherence information, which describes coherence between a first and second channel, is obtained within a hierarchical coding process only. for channel pairs that include a first channel having only left-hand information relative to a listening position and including a second channel having only right-hand information relative to a listening position. Since within the hierarchical process the multiple audio channels of the audio signal are downmixed iteratively to monaural channels, it is possible to choose the relevant parameters of a coding step involving only the channel pairs that carry the information necessary to describe the spatial properties of the audio signal. multichannel audio signal. |
