property Deferred: Boolean;
When set to True the change of parameters of the 3DListener or any 3DBuffer will be deferred and will be commited only this value changes to False. If False any change will be immediatelly executed.
If you need to apply any parameter change immediatelly within some deferred settings you'll need to call the interface methods directly.
This property is available only if the PrimaryBuffer's DS3DListener
property is not nil.
