platform	string	The ID (GUID) of the platform. An object GUID of the form: {aabbcc00-1122-3344-5566-77889900aabb}.
return	array	Data to be returned for every attenuation curve link change. The array of return expressions defines which elements of the Wwise object will be returned. This can include built-in accessors, such as the name or id, or object properties, such as the Volume or Pitch.
return [...]	any of:	A return expression.
	string	Specifies one or many of the built-in accessors for Wwise objects. Possible values: id name notes type shortId classId category filePath workunit parent owner path isPlayable childrenCount totalSize mediaSize objectSize structureSize sound:convertedWemFilePath sound:originalWavFilePath soundbank:bnkFilePath music:transitionRoot music:playlistRoot audioSource:playbackDuration audioSource:maxDurationSource audioSource:trimValues audioSource:maxRadiusAttenuation audioSource:language workunit:isDefault workunit:type workunit:isDirty switchContainerChild:context
	string	Specifies one or many dot-separated accessors that form a query and yields a value or an object reference. Specifying a single @ returns the value of the property for the associated object. Specifying a double @ returns the value of the property for the source of override. Refer to Wwise Objects Reference .
