Note: I can't upload the sample in the uploads forum. Whenever I click on the "add this attachement" or "post new topic" buttons I only get an error message: "This document contains no data"... Here is the thread anyway.

If it's smaller than 9Mb, send it to my e-mail. I'll host it for a while at RW.

Just found my Creative sampler disc, but am unable to get anything off of it using PPCM Ripper.  I can extract the MLP files using the DVDAExplorer program, but as has been noted by others I can't play them.  Will keep trying.

Also, I can't trick WinDVD into thinking I have 7.1 surround.  I have an Audigy 2.  Does anyone know how to do this?

I'm not sure what I have to do to test its authenticity (i.e. is it the original high resolution audio or a downsample?), so people in the know, please analyse this sample ;-)


Downsample

That's so evil...

I still don't understand this bullshit of only allowing Creative card owners to enjoy full quality.

Maybe the sample was originated from 48KHz master... 16/48 or 24/48 shouldn't be too uncommon in recording business, no?

I used DVDAExplorer on my NIN Downward Spiral Dualdisc - it says the tracks are at 48000khz and rips them to my harddisk as MLP files.  I cant figure out how to play them back.  Dvdaripper wont work, there isnt an MKB file in the AUDIO_TS directory on the DVD.  PPCMripper can rip the tracks, they come out as 24bit/48khz though...

Not quite what I was expecting, I thought that most DVD-As are encoded @ 96khz.

But then why upsample it to 96kHz? Just for marketting?

Downward Spiral DVD-A is 48khz.  I believe that's how it was originally recorded.  Remember that was a few years back now.

Would you mind posting a screenshot? I've a hard time picturing what you mean (I don't know much about such things).

Do you happen to know any of the recording details of the clip you posted?  If it's 70s Yes, it must have been analog recording.  If it's later than that, it could have been recorded digitally at 48khz.

Mmm-kay, I downloaded the evaluation program and I see the same. So I loaded the stereo mix too (still 24bit/96kHz), and it didn't show the lowpass. So I tried another DVD-A (The Doors - L.A. Woman), and it's even more obvious, the full band is used. So it's just the 5.1 mix on the "Yes - Fragile" DVD-A that has been butchered??

I wish I could upload more samples and screenshots, but I can't access my web space right now (no idea why). The point is, the tools do work fine, they do extract genuine 96kHz audio. I'm still shocked about that Fragile 5.1 mix though

I wouldn't say it's butchered.  Maybe they just didn't have enough space on the disc to include all 6 channels of the 5.1 mix in 96khz, so they made it 48.

As you said above,

I noticed that you need to set up WinDVD properly in order to extract the right audio (check "24bit/96kHz output" and set up the target audio system to 5.1 in the "audio center").


So the sample rate of the surround mix on the disc is probably 48, it just was output as 96 since you set that option.

If the stereo is fine, then nothing is being downsampled.

How long before some wizard disassembles the windvd codec and decryption code, and comes up with an open-source, self-contained extracting tool ?

I'd say 3-4 months...

Question: PPCMripper says it won't extract multichannel audio, that the disc must be decrypted first.  Could anyone describe how to get the multichannel audio from these discs?

It definitely says "Advanced Resolution Multi-Channel Surround Sound (96 kHz/24-bit)" on the back of the DVD case. I want my money back!
