Editing Direct Stream Digital (section)

==DSD playback options==
Sony developed DSD for SACD, and many disk players support SACD. Since the format is digital, there are other ways to play back a DSD stream; the development of these alternatives has enabled companies to offer high-quality [[music download]]s in DSD.<ref name="positivefeedback">{{cite web |url=http://www.positive-feedback.com/Issue60/dsd.htm |title=The Higher End: From an Editor's Notebook - Downloadable DSD |first=David W. |last=Robinson |date=April 2012 |publisher=Positive Feedback Online |access-date=May 14, 2012}}</ref>

===DSD disc format===
Some professional audio recorders (from [[Korg]], [[Tascam]], and others) can record in DSD format. Transferring this signal to a recordable DVD with the appropriate tools, such as the [[AudioGate]] software bundled with Korg MR-2000S recorder,<ref>[https://www.korg.com/us/products/drs/mr_2000s/ MR-2000S]</ref> renders a ''DSD Disc''. Such discs can be played back in native DSD only on certain Sony VAIO laptops and [[PlayStation 3]] systems.<ref>{{cite web |url=http://www.ps3sacd.com/faq.html#_Toc177216816 |title=PS3 SACD FAQ |publisher=PS3SACD.com |access-date=August 8, 2010 |archive-url=https://web.archive.org/web/20181019113937/http://www.ps3sacd.com/faq.html#_Toc177216816 |archive-date=October 19, 2018}}</ref> Sony produced two SACD players, the SCD-XA5400ES and the SCD-XE800, that fully support the DSD-disc format. In June 2012, [[Pioneer Corporation|Pioneer]] launched a series of SACD players compatible with DSD-disc. The PD-30 and PD-50. In January 2013, [[TEAC Corporation|TEAC]] announced a DSD-disc compatible player, the PD-501HR.<ref>{{cite web|url=http://www.whathifi.com/news/ces-2013-teac-announces-reference-501-the-most-advanced-mini-hi-fi-system-in-the-world|title=CES 2013 Announcement|date=January 8, 2013 }}</ref>

===DSD over USB===
An alternative to burning DSD files onto disks for eventual playback is to transfer the (non-encrypted) files from a computer to audio hardware over a digital link such as USB. The [[USB audio]] 2.0 specification defined several formats for the more common PCM approach to digital audio, but did not define a format for DSD.

In 2012, representatives from many companies and others developed a standard to represent and detect DSD audio within PCM frames; the standard, commonly known as DSD over PCM (DoP), is suitable for other digital links that use PCM.<ref name="DoP open Standard">{{cite web |url=http://dsd-guide.com/usb-link-dsd-audio-pcm-frames-andreas-koch |title=Method for transferring DSD Audio over PCM Frames Version 1.1 |first=Andreas |last=Koch |date=March 30, 2012 |publisher=DSD-Guide.com |archive-url=https://web.archive.org/web/20120515083952/http://dsd-guide.com/usb-link-dsd-audio-pcm-frames-andreas-koch |archive-date=May 15, 2012 |access-date=May 14, 2012 |display-authors=etal |url-status=dead |df=mdy }}</ref> The 1.1 revision added protocol support for higher DSD sample rates without requiring an increase the underlying PCM sample rate.

===Native DSD===
The definition of ''native DSD'' playback is somewhat a matter of philosophy. Generally speaking, it avoids the conversion of DSD data into multibit PCM anywhere along the reproduction chain.{{citation needed|date=January 2022}} Many commercially available DACs now support ''native DSD''.
