Convert 24 bit Audio From A DVD-Video Disc to WAV/FLAC

[DylanCh82]

Hello. I hope this has not been beaten to death already in other posts, but I have been searching the net and this forum all night trying to figure out how to get this done. Any help would be very greatly appreciated.

My final goal is to "rip" (I understand it is not exactly ripping, however for simplicity I will use that term) the audio from my concert DVDs, Dual-Discs, etc. to FLAC. I have a couple that have 24bit 48k LPCM tracks on them, and these are the ones that are causing me to pull my hair out. My plan is to rip to .wav and then convert to .flac.

I can rip the audio off of my DVD into a 24 bit 48k .VOB file, and play that file in VLC player, however I cannot find the right program or get the settings right in the ones I have tried to convert this .vob file to a .wav. I tried using VLC but just got white noise. I have Goldwave, however could not get it to open the .vob file properly...

Any ideas? Am I on the right track? It is getting late and I may have to give up for the night, I can post more info if needed.

I would try to see if DVDDecrypter can handle that disc. DVDDecrypter has the ability to take only the audio from the disc....and the ability to give you one, giant audio file(whole concert) or give you chapters(individual songs).
That should make the audio conversion much easier.

Eac3to using the HD-DVD/Blu-Ray Stream Extractor GUI should do it. Open the vob file, deselect the video, tell it to output the audio stream as wave, and type -down2 into the +Options area next to the audio stream if it requires downmixing to stereo.

tsmuxerGUI should be able to extract the audio. Under the output section, select the "demux" option.

TAudioConverter should make short work of the job.

You could remux the vob file as an MKV using MKVMergeGUI, then use MKVCleaver to extract the audio stream from the MKV file. Or open the MKV using foobar2000 and use it's converter to convert the audio within to a wave file.

DGIndex should open and extract the audio from the vob file.

MeGUI should convert the extracted audio to flac, or you can load the vob file into it's audio encoding section and convert it to flac without needing to extract it first.

Ripping the audio is not the best method to do this, instead of thinking foward you need to think backwards. That is my only hint.

Not much of a hint.

Regardless, I disagree. Ripping (as a first step) IS the best method (not counting leaving it as-is in DVD-Audio or similar format). All other forms of capturing have a much higher likelihood of loss involved.

There is a program called DVD Audio Extractor ..... it could very well get you to 1 point so you may easier get to where you want to go in the end.

First off I would like to say thank you to all the replies! (also I am typing very fast so if there are errors...oh well
I really am impressed at the speed of which people replied, I have been busy with x-mas and just now got a chance to thank you all.

I have got a process for the LPCM tracks...been working on my 5.1 DD and 5.1 DTS DVDs now which is causing me some grief also, so exactly how I got the LPCM "project" accomplished is not fresh in my head, I will need to refer back to my notes which I don't have right now, however I am pretty sure I used eac3to.exe to extract and then ffmpeg to convert to FLAC.

I tried to use DVD Audio Extractor on a couple DVD-Video discs and all it did was lock up my disk drive. The only way I could get it to open was to restart the computer... don't know if anybody else has had this problem or not.

Which thank you for the FFMPEG hint...I had seen that software before but never used it as I thought it was way over my head, however decided this time to try to compile my own version, which did not run for some reason...still need to figure that one out...but also I downloaded a fairly recent build which worked for me. Long story short I now KNOW that fully understanding FFMPEG is way over my head, and after 3 days of researching how in the $^&* to first get then compile and use this program I have been exposed to all sorts of new interesting stuff (command line, source file building, batch file creating, etc.) that really interests the true nerd inside me! I have decided I WILL figure out how to compile my own build of FFMPEG and utilize it, not going to waste hours of late night internet scouring and an angry wife for nothing .

I have a question on the DTS and DD tracks from these concert DVDs and I will post it here because I feel it is related but please feel free to let me know if it should go on a new thread,

Getting a 5/5.1 channel DTS track from a DVD-Video disk:
1) rip selected track with DVD Decrypter by selecting DTS track and stream processing, demux get a .vob output.
2) transcode to seperate mono wavs with tranzcode (I realize DTS is a lossy format and I do not gain anything by this, my main goal is not to loose anything)
3) attempting to use BeSweet to combine all the .wavs into a single, multichannel .wav format ---this is my current problem I get an output file, however the speed is doubled)
4) next step is to convert to multi-channel flac with FFMPEG
5) playback... nothing for now until I get my HTPC built.

Questions:
1) is there a better way to "rip" a DD or DTS track from my DVDs without loosing any fidelity (again I know that both of these formats are lossy)
2) any thoughts on why my output file is doubled?

[DylanCh82]

Am I being stupid here? Can I do the DTS and DD extraction all in FFMPEG?

Cornucopia has no idea what he is talking about. In 2003 delevopled and designed a method to take 5.1 audio files and convert them in to 2 channel mixes. This is for CD's.

In experiments have tried pulling the audio, but will be honest your best is just to use the PCM 2 channel mix for your 2 channel audio.

However when you listen to the 5.1 mix, it sounds so much better than the 2 channel audio, so you want that to mix on your CD's. Now understand, with AC-3 the audio is mixed totally different and it is not designed for PCM wav files. As far as compression, you are not talking about MP3's. If you pull the video/audio track from the DVD that information is not compressed at all.

When you convert the 5.1 to 2 channel audio normally the right speaker gets a lot of the center speakers data, creating a weird balance in the recording. It does sometimes sound ok, but it is not mixed correctly.

What I am designing or creating is for the CAR, my stereo already has 5.1 and DTS, my car has 4 speakers, to make these mixes sound amazing we go backwards and create Quadraphonic recordings out of the 5.1 mixes.

Bat999, thank you again. I figured this out exactly the same time as I posted the "stupid" reply, however I have to say that you have only pushed me down the rabbit hole and I have a long way to go to drag myself back out .
Deter, thank you for the reply, but I think you misread my post. I am talking about a DVD-Video disc here, not a high resolution Blu-ray.. The DTS and Dolby Digital tracks on these discs ARE compressed files using a lossy format, unlike DTS-HD and Dolby-True-HD on a Blu-ray. http://en.wikipedia.org/wiki/DTS_(sound_system)

I don't quite understand the way you're going about it. Are you saying you're transcoding the individual channels to mono wave files and then trying to add them together to make a 5.1ch wave file again? If so..... why??
If you have a multichannel audio file normally you'd just keep it as a multichannel file, whether you convert it to another format or not.

The way I'd do it is to rip the DVD as you normally would so you end up with a DVD's worth of vob and vts files etc on your hard drive. If you want to you can open the ripped files (or the original DVD if you have something like AnyDVD decrypting in the background) and use it's re-author function to split it into individual tracks. It'll split by chapter and many concert DVDs have chapters for each song. Then you'd use DVD Shrink's backup function to "backup" the re-authored DVD to a new location on your drive, and you'd have individual vob files for each song.
From there it's easy to extract the dts audio "as-is" in it's original multichannel form. In my first post I linked to three or four programs which will extract the dts audio. DgIndex is probably the easiest to use, and if you've got a video program on your PC there's a good chance you already have it. Many programs use DGIndex to extract the audio as part of the conversion process. MeGUI and AutoGK both use it.

Anyway, whether you extract the audio from the vob files you've split into chapters, or a vob file of the whole concert, you'll end up with a DTS file, or several, on your PC. If you've ripped the whole DVD (or the main movie) there's usually a bunch of 1GB, sequentially numbered vob files. If you open the first one using DGIndex, it should automatically add the rest and extract the audio from them all as a single file.

Once you have the audio extracted, then it's pretty easy to convert it. Although I'd be tempted to keep the original DTS audio and maybe use MKVMergeGUI to remux it as an MKA file. That's another option.... You could open the vob files using MKVMergeGUI, deselect everything except the dts audio and save the output as MKV. If later you want the original DTS for some reason, MKVCleaver will extract it for you.
Anyway, you should be able to convert it directly to flac and not need to worry about wave files unless you want to edit it. I'd probably just open the dts audio using foobar2000 (foobar2000's dts decoder may be a separate plugin), right click on it and select convert and choose flac. Foobar2000 will convert as many simultaneously as you have CPU cores. Or it'll convert to multichannel wave files. You can pick your desired bitdepth, although 16 bit stops the file sizes from getting too out of control.

I've never used BeSweet so I can't help much there, but logically the speed problem would be caused by the bitrate being changed somewhere in the process, which would probably cause the audio to play faster or slower, but I don't know why it's happening.

Deter's last post has so much wrong and wacky info in it that I am officially calling him a nutter.

I must have downmixed a squillion multichannel audio files using a variety of programs and I've never had a problem with the centre channel being mixed more to the right. Not when downmixing while converting DVDs to AVI, and not when I've downmixed multichannel concert DVD audio to stick on my MP3 player. I don't know what program Dexter uses but he should be using something else.

Again thanks for the posts. I will use the info here to play around with it some more. I think (so far) my questions have been answered. My "overall goal" is to listen to some of the multi-channel music I have sitting on my shelves and never have listened to. I am currently working on encoding all of my CDs (1500+) to FLAC and setting up a home network to steam music across, and as I was doing so I noticed how much multi-channel music I have and have never even listened to and wanted to experiment with a way of archiving that to my computer so I would be easier for me to access it (lazy...I know...but I still spin some vinyl from time to time so that makes up for it )
Thanks again and I hope this thread may help someone else who has similar needs! It sure has helped me.
