Claim One:
1. A device for decoding a coded audio bitstream, the device comprising: a memory configured to store a coded audio bitstream; and one or more processors electrically coupled to the memory, the one or more processors configured to: obtain, from the coded audio bitstream, a representation of a multi-channel audio signal for a source loudspeaker configuration; obtain, in a Higher-Order Ambisonics (HOA) domain, a representation of a plurality of spatial positioning vectors that are based on a source rendering matrix, which is based on the source loudspeaker configuration; generate a HOA soundfield based on the multi-channel audio signal and the plurality of spatial positioning vectors; and render the HOA soundfield to generate a plurality of audio signals based on a local loudspeaker configuration that represents positions of a plurality of local loudspeakers, wherein each respective audio signal of the plurality of audio signals corresponds to a respective loudspeaker of the plurality of local loudspeakers.
