Introduction - Sony SCD-1 Technical Background

1. Introduction.

Super Audio Compact Disc represents a quan-
tum leap in sound quality. Its Direct Stream
Digital ® (DSD) encoding gives music a freshness
and presence unmatched by any other audio
technology. To demonstrate this new format to
the fullest, Sony has built two landmark compo-
nents: the SCD-1 and SCD-777ES Super Audio
CD™/CD players.
In creating these players, Sony discarded many
preconceived notions about digital audio and
digital music reproduction. We had to invent new
approaches, build new architectures and pro-
duce entirely new Large-Scale Integrated (LSI)
circuits. It was to explain these accomplishments
that Sony created this white paper.
