Editing Direct Stream Digital (section)

===DSD processing tools===
DXD was initially developed for the [[Merging Technologies]] Pyramix workstation and introduced together with their Sphynx 2, AD/DA converter in 2004. This combination meant that it was possible to record and edit directly in DXD,<ref>{{cite web|url=https://www.promates.com/music-store/hd-audio|title=Digital HD Audio Formats|access-date=October 27, 2014|archive-url=https://web.archive.org/web/20150621045338/https://www.promates.com/music-store/hd-audio|archive-date=June 21, 2015|url-status=dead|df=mdy-all}}</ref> and that the sample only converts to DSD once before publishing. This offers an advantage to the user as the noise created by converting DSD rises dramatically above 20&nbsp;kHz, and more noise is added each time a signal is converted back to DSD during editing.

The Pyramix Virtual Studio Digital Audio Workstation allows for recording, editing and mastering all DSD formats up to DSD256. A 12.288&nbsp;MHz DSD256 variant based on a 48&nbsp;kHz reference{{efn|{{times|48&nbsp;kHz|256}}&nbsp;{{=}} 12.288&nbsp;MHz as opposed to the more common {{times|44.1&nbsp;kHz|256}}&nbsp;{{=}} 11.2&nbsp;MHz}} is supported. The exaSound e20 DAC was the first commercially available device capable of DSD256 playback at sampling rates of 11.2896 or 12.288&nbsp;MHz.<ref>{{cite web|title=e20 Mk II - the first high-end DAC capable of DSD256|url=http://exasound.com/Blog/tabid/74/articleType/ArticleView/articleId/79/categoryId/8/e20-Mk-II--the-first-high-end-DAC-capable-of-DSD256.aspx}}</ref><ref>{{cite web|title=e20 Mk III - the first high-end DAC capable of 12.288 MHz (DSD256)|url=http://exasound.com/Blog/tabid/74/articleType/ArticleView/articleId/97/categoryId/8/e20-Mk-III--the-first-high-end-DAC-capable-of-12288-MHz-DSD256.aspx}}</ref> The Merging Technologies Horus AD/DA Converter offers sample rates up to 11.2&nbsp;MHz, or four times the SACD rate.

DSD128, 5.6448&nbsp;MHz, twice the SACD rate, has been supported by multiple hardware devices such as the exaSound e20 Mk II DA,C<ref>{{cite web|url= http://www.exasound.com/e20/Overview.aspx|title= exaSound e20 Mk II}}</ref> Korg MR-1000 1-bit digital recorder, Amanero Combo384 DSD output adapter and the discontinued exaU2I USB to [[I²S|I²S interface]]. 

Software supporting DSD includes [[Sonic Studio]]'s Amarra Luxe, Audirvana, [[foobar2000]] with SACD plugin, [[JRiver Media Center]], Roon,<ref>{{cite web|url=https://community.roonlabs.com/t/dsd512-upsampled-free-demo-from-www-wechdomi-org-resolved-with-build-218/24188/7|title=DSD512 ...upsampled free demo from www.wechdomi.org [Resolved with build 218]|date=April 17, 2017|quote=Thanks @wizardofoz, managed to download the 'Wechseldominante - Babel DSD512\Wechseldominante - Babel (DSD512).dff' and playback on my Holo Spring DAC. Direct DSD512 playback is far less computer intensive if it doesn't do any form of conversion. I managed to playback DSD512 without any issue.}}</ref> HQPlayer and Neutron Music Player are all able to handle DSD files of up to DSD512 rate fully natively.
