| Coverage of ITU-R Speaker Configurations
The contribution proposes to add ITU-R speaker configurations to CICP and 3D Audio tables.
Support for Horizontal-Only HOA
Currently, the 3D Audio HOA tools to not have any directivity that lies directly on the horizontal plane. This can be resolved via an additional 64-value codebook and without any changes to bitstream syntax.
Screen-related Adaptation for HOA
In the current specification, HOA audio sound stage adaptation can result is peaks in computational complexity. The presenter noted that an implementation-dependent solution is to pre-compute the adaptation matrix for each production and decoder screen size combination.
The contribution proposes an alternative signalling of production screen size.
