Audio Compact Discs (SACD) The Next Generation Music Carrier
In the constantly
changing and rapidly advancing world of recording technology, Telarc
continually evaluates the latest developments. Ever since producing
its first digital recordings in 1978, Telarc's objective has been
to provide the highest quality music reproduction possible. Now
with the development of the Super Audio Compact DiscTM (SACD), which
utilizes the extraordinary Direct Stream DigitalTM (DSD) recording
technology, the foundation exists to launch a new era of high-resolution
stereo and multi-channel surround recordings.
The new Super
Audio Compact Disc format, created by Sony and Philips, provides
unprecedented sound quality in stereo and discrete multi-channel
surround. To achieve its sonic performance, SACD employs DSD, a
radically new digital encoding technology. DSD samples the musical
signal at a phenomenal 2.8 million times a second, 64 times the
amount of a traditional CD. The result is an extremely smooth digital
waveform with unparalleled frequency response and dynamic range.
Telarc is recording all of its projects using the DSD process.
benefits of SACD do not stop with its performance. The SACD format
supports several disc configurations, including a Hybrid SACD designed
to be completely compatible with the millions of CD players in the
market today. Hybrid SACDs actually contain two complete layers
of music information. One layer contains the high density DSD recording
that can be played in the new generation of stereo and surround
SACD players. The other layer is a conventional CD layer, which
can play on any CD player.
