Abstract
There is inter alia disclosed an apparatus for spatial audio encoding configured to: determine, for two or more audio signals, a first spatial audio direction parameter and a second spatial audio direction parameter for providing spatial audio reproduction: quantize the first spatial audio direction parameter (); transform the second spatial audio direction parameter to have an opposite spatial audio direction (); determine a difference between the transformed second spatial audio direction parameter and the quantized first spatial audio direction parameter (); and quantize the difference ().
