}}</ref> The format is intended for storing individual tracks of DSD audio and has native support for ID3 metadata inclusion. The format defines a "format ID" field that could presumably be used to indicate DST compression. However, the only identifier defined in the spec is number 0 indicating "DSD raw". Files containing DSF data would typically use the<code>.dsf</code> file suffix. No official media type has been registered for the DSF file format.<ref name="Media Types"/> Freedesktop.org uses the unofficial media types <code>audio/x-dsf</code>.<ref name=":0" />
