1. A memory for storing data for access by an application program, the memory comprising:
a simulated reality application (an SR application) stored in the memory; and
a data structure stored in the memory, the data structure including an audio asset, wherein the audio asset comprises audio data and asset metadata, the audio data having therein a sound encoded in accordance with or as specified in the asset metadata, the asset metadata configures the SR application when executed by a computer for composing sound for an SR environment, as the audio asset is rendered in the SR application;
the asset metadata includes a relationship parameter representing a relationship between a listener in the SR environment and a SR object to which the audio asset is attached,
and wherein the SR application dynamically transforms the asset metadata by editing the relationship parameter which alters how the audio asset is rendered in the SR application executed by the computer.
