===DSD over PCM (DoP)===

In addition to actual DSD file formats, a format called ''DSD Audio over PCM Frames'' (DoP) is used for embedding DSD into PCM audio streams.<ref>{{Citation

While DoP is intended to be a wire protocol used for communication between music player application and a DAC, there exists tools that can embed DoP-encoded DSD into FLAC files enabling users to use a non-DSD capable player for DSD playback with their DoP-capable DAC.<ref>{{Citation
