Burn a DVD-AC3 Compatible CD-R

grant+harris writes "This interesting article shows how it is possible to burn AC-3 audio onto a normal CD-R. Will this technology usher a new type of online piracy when DVD-Audio and surround sound systems become more commonplace?" While this is only audio, it is a good step in the right direction.

DVD-Audio?

[nedron]

What does AC-3 have to do with DVD-Audio? DVD-Audio uses Meridian Lossless Packing, not Dolby Digital. The DVD-Audio disc may also have an AC-3 or (preferably) DTS track for backward compatibility, but the main mode is MLP.

You can do more than that...

This has been out for over a year, maybe two. Oddly enough, I was just doing this last night. There's several programs that will do this, in fact there's a program that will do this in one easy step as opposed to SoftEncode...

"This program allows a direct conversion from VOB/AC3 to CD, using BeSweet (freeware) and SurCode DTS (for DTS-CDs : commercial-ware)!! Makes AC3-CDs, DTS-CDs and standard CDDA discs. "

This is way cool. I took my roomate's Dave Matthews DVD, popped it through this program, and out came a burned CD in either DTS-CD, DD5.1, or regular CD. Way cool, and perfectly legal as far as I'm concerned. I'm making a backup and/or transfering the media to a different format.

quite some time ago.

Better than that, you can burn mini-dvd's on to a CD. There are several programs that will burn the ISO DVD directory structure on to a regular CD. This comes in handy for say, when I took my roomate's NIN DVD in DTS, and extracted the DTS track, and burned that onto a dvd-cd. The DTS track is a perfect 550mb. How cool is that. Also good for burning DD5.1/THX trailers onto a CD to take to the home theater shops to test out their systems. You can get full blown .vob's here:

I have my copy with 12 different trailers, including the simpsons THX one. It doesn't work in all players, you need to test them out. :)

Fun programs to have:
Surcode DTS encoder
Sonic Foundry Soft Encode
Gear Pro CD/DVD burner
Scenarist NT dvd authoring program (it's a $39,000 program which can be used to make menus like the Matrix DVD)
vobrator
DVDDecrypter

Please don't use their new-speak...

...unless you really believe that copying some bits is really the equivolent of boarding a ship, raping and killing those on-board, stealing what is left, then burning the ship and the bodies of those you have murdered.

If you want to refer to violation of copyright law, then please call it what it is.

WAV-padded AC-3 not reliable

[yroJJory]

I've done a considerable amount of testing 5.1 formats on CD-R and DVD-R (and variations). Yes, AC3 can be WAV-padded to look like a PCM audio file and subsequently put onto a red book CD-DA disc, but I've found that most older AC3 decoders don't understand the reverse bit-order format.

On the flip side, WAV-padded DTS does work on all DTS decoders, as it was included in the format from the beginning.

Additionally, DTS is a better format because it is fixed-rate 4:1 compression, as opposed to AC3's variable 12:1.
