Claim 13:
14. A device configured to decode a bitstream comprising:
a memory configured to store the bitstream;
one or more processors, coupled to the memory, configured to:
receive the bitstream that includes reorder information to determine how one or more reordered foreground audio objects, in an ambisonics domain, in a first time segment were reordered;

decompress the received bitstream to:
generate the foreground audio objects, in the ambisonics domain, in the first time segment based on the reorder information; and
generate one or more spatial vectors, in the ambisonics domain, wherein the one or more spatial vectors corresponds to the one or more foreground audio objects in the first time segment, wherein the reorder information is based on a swap of spatial positions of at least two of the one or more foreground audio objects in a soundfield such that a first spatial position in the ambisonics domain is associated with a second of the at least two of the one or more foreground audio objects in the soundfield after the reorder of the one or more spatial vectors, and that a second spatial position in the ambisonics domain is associated with a first of the at least two of the one or more foreground audio objects in the soundfield after the reorder of the one or more spatial vectors.
