Direct Stream Digital (DSD)

DSD (Direct Stream Digital) is a digital format that stores audio as a sequence of single-bit values at a very high sampling rate.

MPD understands the file formats dff and dsf. There are three ways to play back DSD:

Native DSD playback is used automatically if available. DoP is only used if enabled explicitly using the dop option, because there is no way for MPD to find out whether the DAC supports it. DSD to PCM conversion is the fallback if DSD cannot be used directly.
