/**
* SECTION: IpatchSampleData
* @short_description: Sample data proxy object.
* @see_also: #IpatchSampleStore
* @stability: Stable
*
* An object which acts as a proxy for sample data and one or more cached
* versions of the same audio but potentially differing in sample format
* and/or storage media. #IpatchSampleStore is used instead of the
* #IpatchSample interface, for increased performance.
