1. A method comprising:
receiving information defining a limited area audio scene within a virtual reality audio scene, wherein the limited area audio scene defines a sub space of the virtual reality audio scene, and wherein the information defines the limited area audio scene by defining a movement capability of a user within the virtual audio scene;
processing only one or more audio scene changes that are within the limited area audio scene without processing one or more other audio scene changes that are within the virtual reality audio scene but outside of the limited area audio scene, wherein processing the one or more audio scene changes for the limited area audio scene comprises determining whether a movement of the user within the limited area audio scene meets a condition of the one or more audio scene changes in order to trigger the one or more audio scene changes; and
processing a change to an audio scene based upon rendering parameters of one or more audio elements within the virtual reality audio scene that are associated with the one or more audio scene changes that are determined to be triggered.
