Spatial Coding of Complex Object-Based Program Material

Immersive audio, capture, transport, and rendering: a review

“…If object audio is supported, JOC parameters can be extracted to restore audio objects for Dolby Atmos immersive audio. In order to further reduce the bandwidth of OBA content, [25] proposes a spatial coding scheme that performs dynamic object-grouping, which represents a complex object-based scene as an equivalent reduced set of object groups. They demonstrate that a 10:1 immersive audio, capture, transport, and rendering, a review reduction in object count can be achieved while maintaining high-quality audio playback and rendering flexibility at the endpoint.…”

“…30). A simplified formulation of HRTF-based XTC approach is as below [49] Out (25) The matrix inversion process can introduce instability, which leads to spectral coloration thus reduced output quality. In order to overcome this problem, regularization is frequently used to reduce the effect of the ill-conditioned frequencies at the cost of losing some amount of XTC accuracy [49].…”
