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.
SACD players are not permitted to offer an output carrying an unencrypted stream of DSD. [57] The first two generations of Sony's PlayStation 3 game console were capable of reading SACD discs. Starting with the third generation (introduced October 2007), SACD playback was removed. [58] All PlayStation 3 models, however, will play DSD Disc format.

Super Bit Mapping (SBM) is a noise shaping process, developed by Sony for CD mastering. [ 1 ] Sony claims that the Super Bit Mapping process converts a 20- bit signal from master recording into a 16-bit signal nearly without sound quality loss, using noise shaping to improve signal-to-noise ratio over the frequency bands most acutely perceived ...
1997 – Alto (CD-521) by Joe Beck & Ali Ryerson is the first commercial recording captured with Sony's DSD recording technology which samples music at 2.8224 MHz (64 x the 44.1 kHz compact disc). 1998 – Just Jobim (CD-524) by Manfredo Fest is the first project captured with the new Meitner DSD conversion technology
The Sony NW-A800 series was the first video-enabled Network Walkman. [15] Announced on March 1, 2007, [ 16 ] this series has a metallic build. A chrome-like strip surrounds the edge of the device, and accenting of the same style surrounds the buttons and makes up the logos on the front.
The 1-bit converter is the basis of the DSD format by Sony. One criticism of the 1-bit converter (and thus the DSD system) is that because only 1 bit is used in both the signal and the feedback loop, adequate amounts of dither cannot be used in the feedback loop and distortion can be heard under some conditions (more discussion at Direct Stream ...
