The big hold-up with the new CD/DVD-Audio dual discs has been the
physical thickness of the actual discs. In order to make the new CD
compatible discs work in many older car audio CD decks, compromises
have been made on the disc that are not true of individual DVD-Audio
or CD discs. For example, because of the bonding process, the CD layer
of the dual disc can now supposedly play only 60 minutes of content,
as opposed to 74 minutes on a traditional red book CD. The DVD layer
of the disc is what record industry technology geeks call a “DVD 5,”
which is a single-layer DVD that is not capable of storing as much
music and aftermarket goodies as a “DVD 9,” which is a dual disc DVD. 
Record industry execs guess that certain content decisions will need
to be made on song edits to make long albums fit on the shorter CD
side of the new flip disc. Tougher decisions will have to be made on
the DVD 5 side of the disc, because if a disc is authored with 5.1
channels of 24/96 MLP surround sound (the best sound you can get,
which can still only be played back on a DVD-Audio player), then other
goodies will need to be left off or down-converted to lower
resolutions. Possible compromises include omitting a lot of video
clips or photo galleries. If space is really tight, 24/96 or 24/192
stereo tracks may be eliminated completely with the CD side being the
only stereo version of the album. 
One possible solution to the storage space problem posed by longer
albums or discs with lots of supplemental information is the idea of
shipping records with two physical discs. Supplemental materials, much
like a DVD-Video movie, can be offered on a CD or additional DVD 5
disc. The raw cost to the label could be as much as $1 per disc, which
would be reflected in the cost of the overall disc packages, which are
being test-marketed this month in Seattle and Boston at $18.99. At
these prices, the discs should come with a second disc because they
still will struggle to complete with blockbuster feature films on
DVD-Video that cost only a few dollars more. Consumers should expect
to see the prices of the CD/DVD-Audio dual discs drop to closer to $14
as the discs become more popular. At $18.99 per disc for albums like
Back In Black on CD/DVD dual disc (the Sony Music dual discs are CD on
one side and stereo music on the DVD 5 side during the test
marketing), it is hard to hold the sales numbers to very tough
scrutiny, as you can go to a Best Buy and pick up the CD-only version
of the album for as much as 40 percent less. If the new discs are to
become popular with mainstream audiences, they need offer much more
content and added values, as well as competitive pricing. During this
test marketing, they got the pricing all wrong.

For the first time, consumers can easily write their own
high-resolution DVD-A's for under $100. 
Minnetonka Audio Software plans to release a home studio 'lite'
version of its discWelder™ software.
discWelder BRONZE will be a basic DVD-Audio authoring program that
allows consumers and prosumers to deliver surround and high-resolution
audio on DVD-Recordable media. The software will arrive in March 2004
with the unprecedented sticker price of $99. 
With discWelder BRONZE, the user can import all Linear PCM formats
supported in the DVD-Audio specification, including surround (up to 6
channels of 24-bit, 48kHz audio) and high-resolution stereo (two
channels of 24-bit, 192kHz audio). Surround and stereo tracks may be
used on the same disc, in WAV or AIFF file format, and
discWelder-burned media will play on any DVD-A player that supports
DVD+R/W.

Who fuckin' cares?

A breakthrough in audio may be music to your ears 
There are two formats for multichannel surround sound, which could do
for recorded music what jet engines did to airplanes 
02/06/04
WAYNE THOMPSON 
If you've been swept off your feet by the magic of multichannel
surround sound on movie soundtracks, then perhaps it's time to take
the next step -- multichannel music. 
For many of us who grew up on two-channel stereo, this is the next
frontier in audio -- a technology that makes the listener feel like
he's at a concert, perhaps in the center of the stage itself. 
We're talking about DVD-Audio and Super Audio CD (SACD) -- digital
formats that give consumers an unprecedented listening experience. 
SACD, co-invented by Sony and Philips, uses something called Direct
Stream Digital (DSD) that samples data in the digital bit stream at a
rate of 2.8 million times a second -- or about 64 times that of
conventional CDs. 
DVD-Audio, on the other hand, uses a special encoding system developed
by Meridian Audio Ltd. to deliver six full-range audio channels with
frequency ranges well beyond the grasp of human hearing. It'll make
the family pooch sit up and take notice. 
Put another way, no data from the digital bit stream is discarded in a
DVD-Audio system. The system captures every breath of a live concert
with a dynamic range (144 decibels), well in excess of the human ears'
dynamic range, which is about 120 decibels. 
So, without getting into a discussion of the principles of acoustic
physics, let's just say that Super Audio CD and DVD-Audio systems are
to recorded music what the jet engine was to airplane travel. 
The only problem with both of these high-resolution music formats is
compatibility. 
For instance, you can't play an SACD on a standard CD player unless
the SACD is a double-layered hybrid disc, meaning that a second layer
of bits on the disc is sampled at the same rate as a regular CD. 
Sony has tried to remedy this by licensing other record labels to
produce more hybrid, multichannel discs. At the beginning of this
year, there were more than 1,200 SACD releases available, half of
which are multichannel surround mixes. 
DVD-Audio discs, on the other hand, won't play on any standard CD
player, but all DVD-Audio titles -- about 700 of them at last count --
will play on all DVD players because the sampling system is the same
as used for movie soundtracks on DVD-Video discs. 
All SACD or DVD-Audio players can play conventional compact discs. 
At last month's International Consumer Electronics Show in Las Vegas,
the advocates for DVD-Audio made a case for their format's advantages
over SACD. 
Their pitch, though, wasn't necessarily about the ultimate sound
quality because, frankly, only a golden-eared audiophile can detect a
quality difference between SACD and DVD-Audio. 
Rather, it was about value relating to disc capacity. A DVD-Audio disc
not only gives a listener a very high resolution surround sound but it
also comes with slide shows, lyrics and music videos -- all for the
price of a single CD. 
All major record companies, except Sony Music, plus a number of
smaller labels, are backing DVD-Audio. 
It's hard to predict which format, in the end, will win out, but
DVD-Audio's edge at the moment is that it uses the pulse code
modulation (PCM) digital audio technology preferred by engineers and
producers, and one identical to that employed in the studio; thus it
provides a direct link from the artist to listeners at home. 
According to Sound & Vision magazine's 2004 Buyer's Guide, there are
more than 30 manufacturers of DVD-Audio players, offering an estimated
160 different models, ranging in price from $130 to $20,000, with
Panasonic, Yamaha, Pioneer and Denon the market share leaders. 
On the SACD side, the buyer's guide lists five manufacturers and 13
players, seven of which are made by Sony, its inventor. 
The best bargain for consumers, though, is the so-called universal DVD
player, which made its debut in 2001. This player can handle both
formats with equal grace and dexterity. 
Sound & Vision's Buyer's Guide lists 19 universal audio models from 14
manufacturers, ranging in price from Pioneer's $239 DV-563A player to
$14,995 for Faroudja's DVP2000, which offers dazzling electronics and
a pedigree that says you've bought the Rolex of sound machines.
Following are four universal players worth a closer look: Denon's
DVD-2200, at $629, offers a full digital bass-management feature on
both formats. The bass-management function allows users to optimize
their sonic performance with any loudspeakers, system and room
environment. Marantz's DV6400 universal player, at $599, provides very
high-quality audio performance, with bass management for SACD discs
and built-in Dolby Digital and DTS surround sound decoding. It also
includes a video-off mode that turns the video circuitry off during
audio-only playback, for enhanced sound quality when listening to
audio-only discs. Yamaha's DVD-S1500, at $399, will be available to
dealers next month. One of the few all-purpose DVD players for under
$400 that includes progressive scan circuitry with processing by
Faroudja, its SACD and DVD-Audio circuits are completely independent
for each format. Onkyo's THX Ultra DV-SP1000, at $2,000, is a
reference grade universal player. It features two digital multichannel
audio iLink (IEEE 1394) outputs for high-resolution 5.1-channel audio
signals. Available in April, the DV-SP1000 boasts outstanding build
quality and can compete with high-end universal players costing twice
as much.

 The big hold-up with the new CD/DVD-Audio 
[cut...]
Occhio che nessuno ha detto, da nessuna parte, che il lato DVD deve essere
un DVD-Audio. Sony, per esempio, per evitare di farsi concorrenza sui
SACD, ha fatto uscire, per il test, dei dischi il cui lato DVD e' un
DVD-Video.

Sony si', Warner, ovviamente, un po' meno (parla di "music distribution
format" e di DVD-Audio"). Il DualDisc e' neutro, dal punto di vista del
contenuto dello strato DVD (potrebbe persino, credo, essere fattibile un
DualDisc con un CD da una parte e un SACD dall'altra, anche se non avrebbe
il minimo senso: ci sono gli ibridi per questo).
Piuttosto, mi piacerebbe avere una qualche conferma o smentita sulla
limitazione a 60 minuti della durata del lato CD; che il lato DVD sia
limitato a un DVD-5 mi pare assodato.

Quindi una vera presa in giro sia per l'audio che per il video.
Non sanno davvero più che pesci prendere pur di vendere qualcosa e con
altri formati alle porte non fanno altro che aggiungere confusione a
