DVD-Audio was endorsed by the Warner Music Group, while the SACD format was endorsed by Sony and Universal Music Group, with an especially high-profile by UMG imprint Virgin Records.[5][6] Despite this, in 2011, The Warner Premium Sound series of albums was released by Warner Music Group, marking the first time the label released titles in a SACD format, with recording in DSD.[7] The series grew to ten rock and pop albums, with Super Audio CD/CD hybrid discs containing both an SACD layer and a standard CD layer.[8]

On August 28, 2013, the Acoustic Sounds label launched SuperHiRez.com (now defunct), which sold mainstream albums from major record labels that were produced with Direct Stream Digital or PCM audio formats.[17][18] On September 4, 2013, Acoustic Sounds announced an agreement with Sony Music Entertainment to provide the company's new digital download service with albums that have been produced or remastered in Direct Stream Digital format.[19]
Note that high-resolution PCM (DVD-Audio, HD DVD and Blu-ray Disc) and DSD (SACD) may still technically differ at high frequencies. A reconstruction filter is typically used in PCM decoding systems, much the same way that bandwidth-limiting filters are normally used in PCM encoding systems. Any error or unwanted artifact introduced by such filters typically affects the end-result. A claimed advantage of DSD is that product designers commonly choose to have no filtering, or modest filtering. Instead DSD leads to constant high levels of noise at these frequencies. The dynamic range of DSD decreases quickly at frequencies over 20 kHz due to the use of strong noise shaping techniques that push the noise out of the audio band, resulting in a rising noise floor just above 20 kHz. The dynamic range of PCM, on the other hand, is the same at all frequencies. However, almost all present-day DAC chips employ some kind of sigma-delta conversion of PCM files that results in the same noise spectrum as DSD signals. All SACD players employ an optional low-pass filter set at 50 kHz for compatibility and safety reasons, suitable for situations where amplifiers or loudspeakers cannot deliver an undistorted output if noise above 50 kHz is present in the signal.
Referred to as DSD512 because the sample rate is 512 times that of CD. It has a sample rate of 22.5792 MHz (512 times that of CD), or alternatively 24.576 MHz (512 times 48 kHz). Hardware such as the Amanero Combo384 DSD output adapter, and exaU2I USB to IS interface, and software such as JRiver Media Center, foobar2000 with SACD plugin (up to DSD256 only), Roon,[30] HQPlayer and Neutron Music Player are all able to handle DSD files of this advanced sampling rate fully natively.
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 downloads in DSD.[31]
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-1/2/1000/2000 recorders, renders a DSD Disc. Such discs can be played back in native DSD only on certain Sony VAIO laptops and PlayStation 3 systems.[32] HQPlayer from February 16, 2011, version 2.6.0 beta includes support for direct/native playback from DSD Interchange File Format (DSDIFF) and DSD stream files (DSF) to ASIO devices with DSD support. Moreover, Sony produces two SACD players, the SCD-XA5400ES and the SCD-XE800, that fully support the DSD-disc format. Only the DSF format is supported. However, since most personal computers have only PCM audio hardware, DSD discs must be transcoded to PCM on the fly with the proper software plug-ins with questionable quality benefits compared to native high resolution PCM sources like DVD or Blu-ray Disc Audio.
There are several alternative ways to store DSD encoded audio as files on a computer. One option is to use DSD native file formats that have been specifically for this purpose. Alternatively, DSD can be stored in general purpose audio formats that have been officially adapted to support DSD storage. Finally, DSD audio can be embedded into PCM audio streams that do not have special DSD support. However, a special decoder is needed to recover the DSD stream afterwards.
DSD Interchange File Format (DSDIFF) is a native DSD file format developed by Philips between years 2000 and 2004 for storage of DSD recordings.[48] The format supports DST compression of the payload as well as annotations used in Super Audio CD production. A single DSDIFF file may store an entire album as a single audio stream together with markers indicating where to cut the individual tracks for the album. Some parts of the audio content may be left out entirely from the resulting SACD. The embedded metadata format is intended for mastering engineers and not consumers. For example, markers indicating beginning of a new audio track have a text field for storing arbitrary text based information. However, there is no requirement for the text to contain the title of the track. A defacto standard for including ID3 metadata in an unofficial ID3 chunk has later formed as consumers have adopted the format for storing individual tracks of DSD audio. Files containing DSDIFF data would typically use the .dff file suffix. No official media type has been registered for the DSDIFF file format.[49] Freedesktop.org uses the unofficial media types audio/x-dff.[50]
Wideband Single-bit Data (WSD) is a native DSD file format developed by 1-bit Audio Consortium in 2002.[51] The consortium was established by Waseda University, Sharp and Pioneer a year earlier.[52] In 2012 the consortium published an updated 1.1 version of the specification.[53] The WSD header has a field for storing an absolute timestamp in samples since midnight. The timestamp makes it possible to accurately know how much time passed between two recordings made consecutively on the same physical recording device. Korg portable recorders MR-1, MR-2, MR-1000 and MR-2000s support WSD alongside other DSD based formats.[54][55][56]
DSD Stream File (DSF) is a native DSD file format developed by Sony around year 2005.[57][58] The format is intended for storing individual tracks of DSD audio and has native support for ID3 metadata inclusion. The format defines a "format ID" field that could presumably be used to indicate DST compression. However, the only identifier defined in the spec is number 0 indicating "DSD raw". Files containing DSF data would typically use the.dsf file suffix. No official media type has been registered for the DSF file format.[59] Freedesktop.org uses the unofficial media types audio/x-dsf.[50]
WavPack is a generic audio storage format supporting various different forms of audio.[60] Compressed DSD audio is also supported by the format.[61] The DSD support was initially introduced with the release of WavPack software suite version 5 in December 2016.[62] Files containing WavPack data would typically use the.wv file suffix. No official media type has been registered for the WavPack file format.[63] Freedesktop.org uses the unofficial media types audio/x-wavpack.[64] Since WavPack supports multiple formats the suffix or mime type alone do not indicate the presence of DSD audio.
In addition to actual DSD file formats, a wire format called DSD Audio over PCM Frames (DoP) is used for embedding DSD into PCM audio streams.[65] DoP makes it possible to circumvent any PCM-only component preventing DSD capable DAC from receiving the raw DSD data required for native DSD playback. While DoP is intended to be a wire protocol used for communication between music player application and a DAC, there exists tools that can embed DoP encoded DSD into FLAC files enabling user to use a non-DSD capable player for DSD playback with their DoP capable DAC.[66] DoP is not backward compatible with PCM. Thus, a DoP stream is likely to sound broken when played back by an unsuspecting PCM-only DAC, while a DoP capable DAC can detect the presence of DSD data, extract it from the PCM and play it back as DSD.
It was designed to be a simpler, more space-efficient way of storing digital music data than PCM. Importantly, DSD was also designed to be easy to convert to PCM files with sampling rates based on multiples of 44.1kHz.
While hi-res download sites are far and few between these days, those audiophile music sites that are still around mostly sell DSD downloads. The likes of HDtracks (opens in new tab), and Native DSD (opens in new tab) are good places to start.

In other words, the radius should increase in proportion of the square root of the file size. Instead, judging by the eye, the radius seems to increase proportionally with file size, which, if it is the case, is not correct because it exagerates the increase in file size by the power of two.
You can choose to download Stereo, Binaural and/or Multichannel DSD 256, DSD 128, DSD 64, and DXD. A growing number of albums are also available in the popular Stereo DSD 512 format as well as the latest Stereo DSD 1024.
DSD files contain 1 bit audio with pulse-density modulation encoding. The DSD 64fs version of this system has also been used to store DSD audio signals on SACD discs. DSD can be recorded in Standard Rate (2.8 MHz or 64fs), Double DSD (5.6 MHz or 128fs) and Quad DSD (11.2 MHz or 256fs). 2ff7e9595c
