Multichannel Ring Upmix

Document Thumbnail

Multichannel spatial decompositions and upmixes have been proposed, but these are usually based on an unrealistically simple direct/ambient sound model, not capturing the full diversity offered by N discrete audio channels, where in an extreme case each channel can contain an independent sound source. While it has been argued that a simple direct/ambient model is sufficient, in practice such is limiting the achievable audio quality. To circumvent the problem of capturing multichannel signals with a single model, the proposed “ring upmix" applies a cascade of 2-channel upmixes to surround signals to generate channels for setups with more loudspeakers featuring full support for 360-degree panning with high channel separation.
