is 50% data compression using the DSD (Direct Stream Digital) protocol

DVD-A and SACD both offer advantages as well as disadvantages. SACD
discs can not be played on any DVD player, but that can even happen to some
DVD-As! While DVD-A expands on the success of DVD-Vs, SACD (being a
high-end, technically superior product) is facing a tough challenge, even
though it is completely reversely compatible with CDs and CD players. Get

FORMATS & MEDIA THAT MAKE SENSE
On what format a musical surround production will later be pressed makes
pretty much no difference, regardless of whether it is DVD-V, DVD-A, CD or
SACD. What is of much higher importance is the actual surround format.
Basically, there are currently 3 plausibilities:
1. If you want to listen to a surround mix at home or at the studio, you can use
multi-track hardware or software that was also used to create the mix.
Advantage: Mix available for manipulation at all times.
Disadvantage: Not compatible to popular surround formats; complete set
of equipment hast to be powered up (on average, at least a computer plus
an audio sequencer software plus surround/amplifier speakers.
2. Convert the completed mix into DOLBY
®
Digital or DTS
®
format.
Advantage: Compatible worldwide, almost all DVD players/surround
amplifiers can play it.
Disadvantage: Expensive encoder/software required.
3. Convert the completed mix using the WINDOWS
®
Media Encoder.
Advantage: Easily exchangeable via the internet, can be played on almost
any WINDOWS
®
XP PC, the encoder is free
Disadvantage: Not really widespread, high data compression, can not be
played on traditional DVD multi-players right now.
