Audio scene change signaling

An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to:

• receive information defining a limited area audio scene within the virtual reality audio scene, wherein the limited area audio scene defines a sub space of the virtual reality audio scene, wherein the information defines the limited area audio scene by defining a movement capability of a user within the virtual audio scene;
• process 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 the one or more audio scene changes for the limited area audio scene are processed by 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
• process 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.

A computer program product embodied on a non-transitory computer readable medium, comprising computer program code configured to, when executed on at least one processor, cause an apparatus to:

• receive information defining a limited area audio scene within the virtual reality audio scene, wherein the limited area audio scene defines a sub space of the virtual reality audio scene, wherein the information defines the limited area audio scene by defining a movement capability of user a within the virtual audio scene;
• process 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 the one or more audio scene changes for the limited area audio scene are processed by 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
• process 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.
