Direct Stream Digital (DSD) is a trademark used by Sony and Philips for their system for digitally encoding audio signals for the Super Audio CD (SACD).. DSD uses delta-sigma modulation, a form of pulse-density modulation encoding, a technique to represent audio signals in digital format, a sequence of single-bit values at a sampling rate of 2.8224 MHz.
In a 2014 study, however, Marui et al. found that under double-blind conditions, listeners were able to distinguish between PCM (192 kHz/24 bits) and DSD (2.8 MHz) or DSD (5.6 MHz) recording formats, preferring the qualitative features of DSD, but could not discriminate between the two DSD formats.
Digital eXtreme Definition (DXD) is a digital audio format that originally was developed by Philips and Merging Technologies [1] for editing high-resolution recordings recorded in Direct Stream Digital (DSD), the audio standard used on Super Audio CD (SACD).
The 'Music' category is merely a guideline on commercialized uses of a particular format, not a technical assessment of its capabilities. For example, MP3 and AAC dominate the personal audio market in terms of market share, though many other formats are comparably well suited to fill this role from a purely technical standpoint.
The format used for SACD mastering and 5.1-channel downloads – file extension for DSDIFF files DSD Direct Stream Digital is a 1-bit method of storing audio on digital media. The audio format used for Super Audio CDs (SACD) with effective 20-bit resolution. DSDIFF
An audio format is a medium for sound recording and reproduction.The term is applied to both the physical recording media and the recording formats of the audio content—in computer science it is often limited to the audio file format, but its wider use usually refers to the physical method used to store the data.
WavPack compression can compress (and losslessly restore) 8, 16, 24, and 32-bit fixed-point, and 32-bit floating-point PCM audio files in the .WAV file format. It can also handle DSD input in DSDIFF or DSF format. [2] It also supports surround sound streams and high sampling rates. Like other lossless compression schemes, the data reduction ...
Linear pulse-code modulation (LPCM, generally only described as PCM) is the format for uncompressed audio in media files and it is also the standard for CD-DA; note that in computers, LPCM is usually stored in container formats such as WAV, AIFF, or AU, or as raw audio format, although not technically necessary.
