- Direct_Stream_Digital abstract "Direct-Stream Digital (DSD) is the trademark name used by Sony and Philips for their system of digitally recreating audible signals for the Super Audio CD (SACD). Practical DSD conversion was pioneered by Andreas Koch and Ed Meitner of EMM Labs. Koch and Jonathan Tinn later founded Playback Designs, which pioneered the transfer of DSD files over USB connections. DSD technology was later developed and commercialized by Sony and Philips. Philips later sold its DSD tool division to Sonic Studio, LLC in 2005 for further development.DSD uses pulse-density modulation encoding—a technology to store audio signals on digital storage media that are used for the SACD. The signal is stored as delta-sigma modulated digital audio; a sequence of single-bit values at a sampling rate of 2.8224 MHz (64 times the CD Audio sampling rate of 44.1 kHz, but only at 1⁄32768 of its 16-bit resolution). Noise shaping occurs by use of the 64-times oversampled signal to reduce noise/distortion caused by the inaccuracy of quantization of the audio signal to a single bit. Therefore it is a topic of discussion whether it is possible to eliminate distortion in one-bit Sigma-Delta conversion.DSD-CD has been marketed as an audiophile medium, primarily in Hong Kong with music by Cantopop artists such as Sally Yeh. DSD technology may also have potential for video applications. A similar structure based on pulse-width modulation, which is decoded in the same way as DSD, has been used in Laserdisc video.[citation needed]".
