Is my DVD to WAV audio rip real lossless ?...

Hi, I'd like to rip a couple of audio tracks from a musical DVD for an edit. As I'm untutored to PCM audio rip, nor to the audio channel matter if there are dialogues were it can be removed, I mean to record it with the default magnetophone of my computer and edit the few seconds of unwanted dialogues with another mix that should fit.

The DVD concerned is actually "Star Wars A Musical Journey" and is said to have a high bitrate and very good sound quality.

... So the question is: is the conversion made in such a way is good / accurate, or is there any loss occuring ?

Not sure if I totally understand the post. If you "rip" an audio track from a DVD, then nothing is lost.

If however you are converting to something else, or recording from your computer to a cassette (magnetophone???) then there are losses involved.

There is a simple default tool in the accessories under Windows that is named "Magnetophone". It allows you to create or record files in Wav form from 8,000 Khz 8bits mono to 48,000 Khz 16bit Stereo.

You just have to run your music (DVD or whatever) + to take care of the 3 main volumes, and cut all others (microphone/aux, etc...). I use to fix wave vol. at maxi, recording vol very low, and computer main volume more or less low.

...

... Am I the only one to use these toys ?

So not a real "rip" I imagine, as I guess it's an immediate stereo convertion of the DVD audio...?  To notice I don't know a damn thing about the audio properties from DVD. (But I guess there may be more than 2 channels...)

Ah, now I understand - "Microsoft Sound Recorder" is named "Magnetophone" in the French version of Windows.

I have used that tool before, but I wouldn't recommend it for your purposes.

The easiest way would be to use DVD Decrypter in IFO mode, with stream processing enabled, to extract the audio track you need.

That's great Moth3r, thank you very much.

I'll check about this DVD Decrypter then. I think I heard about it when I searched for an answer the first time. I'll let you know.

 Indeed, easy to do... But that's where I'm entering a new world that is all what I'd liked to avoid... I expected to have directly a AC3 or PCM file...

... Of course not. That leads to seek for another tool to convert the Vob to wav. isn't it ? Why did I felt it ?

Also I still don't know about what is made such a track of, if it is possible to remove SFX from it etc... Because if I convert a Vob to Wav, I guess it can't be anything else than a 2 stereo track.

Well... Does it really make a difference with the Microsoft Sound Recorder ?

Edit: ah... as far as I understand now watching the DVD Decrypter screen, looks like the AC3 as 6 Channels and the PCM as 2...

I even don't have a 5.1 plugin on my PC so you know !

You should have ended up with an AC3 file or a WAV file. Did you click the "stream processing" tab?

You can use something like azid or besweet to decode/split an AC3 file into mono WAV files for each channel.

Yes, and I tried both "demux" and "raw". I haven't tried the "direct stream copy". Would that be the mistake ?

 Yep, I saw besweet looks sweet.

"Demux" should work. What audio streams are present on the DVD? Put a tick in the box next to each stream you want to demux.

What output do you get?

That's what I tried:

It gives both VOB+IFO, but only the VOB from PCM can be readen by my dvd viewer.

For info, here are the input (default... I don't know what is this all about, excepted the chapter selection)

Ah - now I remember, there's a peculiarity in the way DVD Decrypter dumuxes the streams. You need to select/highlight the audio stream and demux each one individually.

Alternatively you could just rip the whole DVD to your hard drive and from there use PGCDemux, which is much more logical in operation.

 You mean the PCM or the AC3 ?

... Or do you mean the Chapters ?

Or do you mean the VOB files I obtained. (Sorry I told you: 0 knowledge + the langage obstacle)

The first time I tried I only selected the AC3... Well, I'll give it a try.

And I'll stay with DVD Decrypter... I won't rip any more thing in the future and I'm a little annoyed with having ten softwares for something I'd make only once.

OK, forget the tick (check) boxes - they are not relevant to demuxing, sorry about the misinformation.

You see in your screenshot above, the video stream is the one selected (the grey highlighting is around the "0xE0 - Video" text). You need to click on the text that says "0x81 - Audio", then demux. After the operation is complete, do the same for the PCM audio stream "0xA0".

You should end up with an IFO file, a stream information TXT file and the two demuxed audio files.

 I think I already have tried and had to name the second stream with another name for it doesn't erase the 1st one... But I'll try again.

... sorry about the misinformation.

 Please don't apologise. You're great to help me !

And I'm alright...

Thanks Moth3r,

It would have worked earlier if I didn't change the name of the 2nd file, afraid I was to erase the first !

There's a lot of settings to convert AC3 to 6ch wav so I'll watch to find the simplest way. My first try is successfull though.
