SDDS audio track ?

[JamesTKirby]

I borrowed my friend's Amelie PAL R2 disc.

Here are the audio tracks (from SmartRipper):

Stream[002] X=[[0x80] Audio Français AC3(6Ch) 48kHz ] [] [] [] []
Stream[003] X=[[0x89] Audio Français SDDS(5Ch) 48kHz ] [] [] [] []
Stream[004] X=[[0x82] Audio Français AC3(2Ch) 48kHz ] [] [] [] []

There's a possibility that SmartRipper (v2.41) has misinterpreted the SDDS track but I find that a bit unlikely.

Now, in another thread someone told me that SDDS audio is not for consumer use (i.e. only for theaters). I believe him, but let's elaborate on this... can I take some advantage of this SDDS stuff ? Is it better than the AC3 tracks usually ?

Btw, this is not the first DVD I have found an SDDS track on.

Thanks for any input,

@JamesTKirby,

I'm afraid it's DTS, better try DVDDecrypter just to make sure.

Think about it, SDDS is a 7.1 format, just as Roberto explained, why should there be only 5 channels then, as reported by smartripper ?

cheers

Another point, besides the fact of smaller number of channels, is that, AFAIK, it's impossible to throw a SDDS stream in a DVD. The only SDDS encoder available takes the audio streams from the source and prints it directly in the movie celluloid. It's not recorded to a file or something like that first.

Now, if that wasn't reason enough, the only SDDS decoder works only with celluloid as well. So, what DVD maker, in his right mind, would add a audio stream that noone in the world would be able to decode? :)

Hi,

I use SmartRipper only to rip my DVDs and Smartripper ALWAYS prints SDDS for DTS audio tracks.

LOL. Indeed, it says SDDS in my Hell Freezes Over DVD, and I'm bloody sure that's DTS. :D

Simply a silly bug in SmartRipper.

BTW: Using version 2.40

Edit: DVD Decrypter 3.1.3.0 recognizes DTS normally.

Yep, thanks for clearing this up, all of you :)

I'll try get a brain from somewhere, just in case ;)

Actually NUENDO allows you to create SDDS audio tracks!
They are 7.1 sound.

The difference between 7.1 normal and 7.1 SDDS is

normal Left/Right, Center, LFE, Surround Right/Left, Left/Right Surround

SDDS Left/Right, Left/Right Center, Center, LFE, Left/Right Surround

Basically there are 5 front speakers, which makes sense for large theaters.

So I assume that if you can create SDDS you can use them? Then again as NUENDO is high-end audio program, proberly used to create source file to be put onto film?

hope this helps in some small way:)
