mix, equalise, control dynamics of, and so on) DSD data directly, and they are Merging Technologies' Pyramix and Sony's Sonoma. As I understand it, there are currently only two DAWs that can process (ie. Processing native DSD streams in a DAW environment is possible in a fashion, but isn't easy and has to contend with some significant technical issues. A disc without that physical copyright‑protection data is not playable on current standard SACD players. Copyright-protection data is embodied in a physical modulation of the width of the data‑stream 'pits', and only licensed SACD production plants have the technology to do that. The Super Audio CD (SACD) uses this data format for its 'high resolution' stereo and (if provided) surround tracks, while often also including standard Red Book CD stereo audio on a separate physical layer in the disc (the so called Hybrid Disc, which accounts for most commercial releases). However, the standard DSD rate has long been argued as insufficient, and a higher DSD rate of 5.6448MHz is now offered by some recorders, including the Korg range. The standard rate is 64 times 44.1kHz, which is 2.8224MHz.

DSD - Direct Stream Digital - is a generic PCM digital audio data format, but one that uses only one bit at a very high sample rate. SOS Technical Editor Hugh Robjohns replies: DSD and Super Audio CD are related but different things, and it might be worth clarifying that first.

Steinberg released software support for DSD some time ago in Cubase, but is it possible today to use DSD with Cubase or other desktop recording systems? If not, what are the alternatives to setting up a DSD workflow for recording, mixing and mastering to Super Audio CD? The DSD/SuperAudio CD format seems to slowly be coming back into focus, with recent releases from Korg and Sony, after many thought it was dead. Merging Technologies' Pyramix is one of a very few Digital Audio Workstations capable of processing DSD (Direct Stream Digital) data directly.
