''DSD Interchange File Format'' (DSDIFF) is a native DSD file format developed by [[Philips]] between 2000 and 2004 for storage of DSD recordings.<ref>{{Citation

}}</ref> The format supports [[DST compression]] of the payload as well as annotations used in Super Audio CD production. A single DSDIFF file may store an entire album as a single audio stream together with markers indicating the location of individual tracks for the album. Some parts of the audio content may be left out entirely from the resulting SACD. The embedded metadata format is intended for mastering engineers not consumers. For example, markers indicating the beginning of a new audio track have a text field for storing arbitrary text-based information. However, there is no requirement for the text to contain the title of the track. A [[de facto standard]] for including [[ID3]] metadata in an unofficial ID3 chunk was later developed as consumers adopted the format for storing individual tracks of DSD audio. DSDIFF files typically use the <code>.dff</code> file suffix. No official [[media type]] has been registered for the DSDIFF file format.<ref name="Media Types">{{Citation
