DXD (Digital eXtreme Definition) is a PCM samplerate developed specifically by Merging Technologies. DXD is a 352.8 kHz/24bit audio signal, which is used to be able to seamlessly move a DSD signal into PCM (standard method of digitizing audio) world so EQ, dynamics and other effects processing can occur. The combination of DSD256, DXD and a timeline which can automatically do samplerate conversions with the most transparent SRC on the planet is what makes Pyramix the most sonically impressive workstation ever made.
