The Super Audio CD Format
Super Audio CD is the most fundamental improvement in digital music
reproduction since the CD itself. No surprise. It comes from the people who
invented the CD: Sony and Philips.
- Hybrid Disc
Furthermore, there is an option to add a separate CD layer to the DVD disc: the so called Hybrid Super Audio CD. Hybrid SA-CDs can be played back on virtually all CD drives and players as well as all standard DVD-Video systems. This makes Super Audio CDs compatible with all 11 billion CD and DVD players used around the world.
4 types of Discs
Every multi-channel Super Audio CD includes a separate 2-channel
stereo mix, done by the hand of the producer—not by a computer.
There are four different SA-CD configurations commercially available to record companies:
vast majority of SA-CDs introduced to the market today are of the hybrid
type, containing the CD layer. This disc plays on a CD and DVD player, at
are also SA-CDs without the CD layer, the so-called single layer discs. These
cannot be played on a standard CD player. The advantage is that this is
an entirely secure digital carrier.
Both the hybrid and single layer SA-CD can be released as a stereo-only album, or as a stereo plus surround album.
Super Audio CD offers the worlds most secure digital carrier, utilizing
a combination of physical and electronic protection barriers. These are layered
around the audio content in five independent layers, including a combination
of mechanical and encryption-based protection systems that cannot be broken
using any current hacking technique.
The end result is that when you buy a Super Audio CD in a music store, you can be confident that its the genuine article and not an illegal, inferior quality copy.
The CD layer on the hybrid disc is similar to a conventional CD in that its open to copying onto other carriers for home use.
