Claim:
1. A method, comprising: receiving, in an input interface to an encoder component of an audio rendering system, audio data comprising audio objects, the audio objects comprising audio object signals and associated metadata, the associated metadata including at least audio object size data; determining, by a large object detection component based on the audio object size data, a large audio object having an audio object size that is greater than a threshold size, wherein the large audio object is spatially diffuse and requires a plurality of speakers to reproduce the large audio object; and performing, in a decorrelator component coupled to the input interface, a decorrelation process on audio signals of the large audio object to produce decorrelated large audio object audio signals that are dependent on a defined location of the large audio object and other information, wherein the decorrelated large audio object signals are mutually independent of one another, and the decorrelation process comprises adjusting a level of each of the audio signals by adjusting a respective audio gain for each of the audio signals to generate the decorrelated large audio object audio signals corresponding to a speaker feed to each speaker of the plurality of speakers, and further wherein the plurality of speakers covers a large spatial area.
