A device obtains an object-based representation of an audio signal of an audio object. The audio signal corresponds to a time interval. Additionally, the device obtains a representation of a spatial vector for the audio object, wherein the spatial vector is defined in a Higher-Order Ambisonics (HOA) domain and is based on a first plurality of loudspeaker locations. The device generates, based on the audio signal of the audio object and the spatial vector, a plurality of audio signals. Each respective audio signal of the plurality of audio signals corresponds to a respective loudspeaker in a plurality of local loudspeakers at the second plurality of loudspeaker locations different from the first plurality of loudspeaker locations.
