Ya know, I was just going to ask what was meant by a DAD. Thanks for the info.discWelder BRONZE makes DVD-Audio discs only and supports 24/192 and 24/96 stereo and well as a whole bunch of other combinations of sampling rate and bitdepth. The full capabilities of BRONZE, STEEL and CHROME are defined in their respective manuals.
You can get the BRONZE manual on http://www.discwelder.com in the Downloads section.

Hi CDR,
It is great to see some industry representation. There are many folks here who are intrested in and confused about creating their own hi-rez discs. Hopefully AA will provide a valuable if not always civil feedback loop for your products.
A guy/girl from Minnetonka! Welcome aboard!To clarify, some years ago before DVD-Audio was conceived, Classic Records and Chesky Records realised that the DVD-Video specifications allowed for two-channel 24-bit 96kHz PCM. They decided to release audio-only discs in this form, and Classic coined the phrase "DAD" (for "Digital Audio Disc" I guess). They're nothing special, just a DVD-Video disc with a fancy name.

For those who can't be bothered downloading the manual, doesn't 192kHz 24-bit require MLP packing, and therefore one needs a $2,500 software encoder to enable that facility?
A misconception. The problem is the maximum data rate possible with the dvd mechanisms in use. That data rate is ~9.6 Mbps.192000 x 2 x 24 = 9.2 Mbps
96000 x 4 x 24 = 9.2
48000 x 6 x 24 = 6.9These are all good.
96000 x 5 x 24 = 11.5
Uh oh.
MLP encoding (Meridian Lossless Packing, PPCM, Packed PCM) reduces the data rate for 24/96 5.0 and 5.1 to a manageable number.
Hi CDR interesting moniker for someone from Minnetonka?...
If you have any influence with those people at your outfit..I would respectfully suggest that the issue of having both music files authorized.for playback in billions of standard DVD machines.be made available and easily via the use of the discwelder product ...even if its an update via the web....many thanks..will probably get one whilst I am over there...in just a few hours.....Dave
