Abstract
An apparatus configured to: determine at least one spatial audio parameter for providing spatial audio reproduction; determine at least one transport signal; determine at least one coherence parameter for at least two frequency bands, wherein a sound scene is configured to be reproduced based, at least partially, on the at least one transport signal, the at least one spatial audio parameter, and the at least one coherence parameter; and provide the at least one transport signal, the at least one spatial audio parameter, and the at least one coherence parameter for encoding.

An apparatus comprising:
- at least one processor;
- and
- at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to:
- determine at least one spatial audio parameter for providing spatial audio reproduction;

- determine at least one coherence parameter for at least two frequency bands, wherein a sound scene is configured to be reproduced based, at least partially, on the at least one transport signal, the at least one spatial audio parameter, and the at least one coherence parameter;
- and
- provide the at least one transport signal, the at least one spatial audio parameter, and the at least one coherence parameter for encoding.
