Hi all,

I've seen several posts about extracting audio from a blu-ray or DVD audio disc, but I haven't seen this situation yet.
I have an .iso. It is a remaster of Tarkus by ELP and is in 5.1 audio.
The video is just a static image of the Sony logo, so I'm not really interested in that.
Mounting the .iso gives me the audio_ts and video_ts directories.

When I look at MakeMKV it offers to extract as a .mlp file (which I understand MC doesn't play) or I can do flac (and some others).
The Flac option (and the others) only allow for 2-channel.

Does anyone have a solution that will retain the 5.1 audio?

Best,
Stu

DVD Audio Extractor is what I used in the past to extract audio from DVD/BD. Sadly, it's not free though but it works great!

[JimH]

For DVD, I think you could rip with MC and then convert.

Thanks for both replies. I see DVD Audio Extractor has a free 30 day trial, so I can check out both options.

I'm actually not even sure I'll listen to the 5.1 that often, but I'd like to have it, for when my wife and daughter are out of the house (my son's into it)

It has been awhile since I looked at DVD Audio Extractor, but as of then, it would not extract hi rez audio from DTS HDMA, only the lossy core DTS.  I was disappointed when I discovered that during my own evaluation period.  So, I have not relooked at it.

I have tested the following freeware which works as advertised for extracts of BD or DVD audio to FLAC, including DTS HD MA:

http://www.videohelp.com/software/AudioMuxer

It seems a little complex, and I have not yet used it all that much yet.  It does break each BD chapter into a separate "track" file in FLAC. No tagging is carried over from the BD.  You have to do that tagging manually.

[mark_h]

For discs with no PCM you can dump the high resolution DTS stream using DVD Audio Extractor, which MC can play
or convert to FLAC...

[fitbrit]

Or simply use MakeMKV and then tag the resulting mkv as audio in Media Type. Uses up more space, but is the simplest way.

[ssands]

Thanks for all the replies.

I think I must be missing something.

It is a DVD-Audio.
When I use DVD-Audio Extractor, it reports MLP (48kHz 24bit 6 channel). (See first attached photo).
When I use DVD-Audio Extractor, and select anything other than Direct Stream Demux (which yields MLP files), I do not have an option for the original 5.1 audio, ONLY mono or stereo. It does not seem to support for than two channels in any conversion.

When I tried MC convert function, MC reports "No tracks to format". See the second attach screen clip). All the files are vob and bup, etc. I don't know which to select, but when I double click on the icon that MC shows me, it plays.

The third clip displays what MC sees when I point it at the virtual ROM drive.
I'm fairly ignorant of all the different formats, so I have no idea about a DTS stream, but I don't see any DTS files.
I tried AudioMuxer but it doesn't understand vob, bup etc files, nor does it list MLPs in the file formats it knows.
I tried MakeMKV and it went ahead and made an MKV that plays. I have not tagged it as audio yet, so I don't know if all the channels came through or not.
Will report back.

[ssands]

...and MakeMKV only made stereo. No 5.1

[mark_h]

For MLP files, just rip to FLAC with DVD Audio Extractor...  I just did exactly that with a disc I have here and got a 96/24 6 (5.1) channel FLAC from a 96/24 6 channel MLP source.

I just did that. MC reports a 2 channel input. I used DVD Audio Extractor V7.3.0

[mark_h]

Well, I suppose there could be something peculiar about that disc, but generally speaking ripping multichannel isn't an issue...

When I look at DVD Audio Extractor, it does not give an option for more than two channels when using FLAC.
Does the interface you are using in DVD-AE allow for more than stereo?
I can only choose Mono or Stereo.

[mark_h]

Yes - in the FLAC encoder options

Sample Rate: Same as input
Channels: All 6 Channels (or I can select 'mono' or 'stereo')
Bits per sample: 24 bits

[ssands]

Channels: All 6 Channels (or I can select 'mono' or 'stereo')

Ha! I don't have that "All 6 Channels" option.
Now, I gotta figure out why...

[craigmcg]

Just guessing but it could be a limitation of the trial version.

[JimH]

The trial version is only time limited.  It has the same features as the full version.

[ssands]

That's correct. They do state the trial is fully featured.
So, I can't figure out why I wouldn't have the 6 channel option.
So weird.

[ssands]

When I select FLAC as my encoding option (and only get an option for mono or stereo), it states I have FLAC V1.3.1 (see screen clip)
Does your version of DVD-AE show a different version?

[mark_h]

1.3.1 here also...

Tested a bunch of discs with MLP, both 96/24 and 48/24, and all show 6 channels when the multichannel tracks are checked.

[blgentry]

A little extra info about DVD-A discs:  If you are definitely talking about a DVD-A and NOT a Blu-Ray disc of some sort...

DVD-As usually have a compatibility DVD layer that contains a lossy version of the audio.  Usually Dolby Digital, but it could also be DTS of course.  This is so people without a DVD-A player can still play their DVD-A discs on a normal DVD player.  That's probably what your screen shot above is showing.  There's normally a video stream too, but it tends to just be a screen shot of the album cover or something like that.

I've only ripped a couple of DVD-A discs using DVD Audio Extractor.  I used the Mac version, since my Mac is my everyday computer (I don't use Windows).  On that version, I absolutely had the option to rip the stereo and multi-channel tracks separately.  I remember because the size of the multi-channel tracks was HUGE compared to stereo.

Importantly, as far as I know, DVD-AE is the only program that will actually rip DVD-A audio from a DVD-A disc. 

Brian.

[ssands]

I'm way out of my depth on this unfortunately.

The .iso opens into Audio_ts and video_ts folders. The video (as far as I know) is just a couple of static images, nothing more.

DVD-AE will extract .mlp files, or, as I mentioned, stereo flac files. For some reason, it will not allow me to extract multi-channel.
DVD-AE also reports that the music is 6 Channel.

Question: If I want MC to play some files, which do I choose? (vob, bup, or something else altogether)?

[syndromeofadown]

It seams you are getting something simple and making it complicated.

Use DVDAE for everything except DTS HDMA for which you should use MC.

Neither DVDAE or MC play or extract from an iso. Unless of course the iso is mounted, and in that case it acts just like a disc inserted into a dvd drive that both programs can read. You can mount an iso with Virtual Clone Drive or similar.

Once mounted use the open disc option in DVDAE. Do not use "open dvd files"

Once mounted play the disc in MC by selecting it in drives and devices.

You can rip, or extract, the iso to a hard disc folder.

Once ripped you can use "open dvd files" in DVDAE or play the Video_ts.ifo in video_ts folder with MC.
Note that the Audio_ts folder contains the DVDAudio data that MC won't play (that's why you extract it)

[ssands]

Well, I think I *may* have found the issue.

I mounted the .iso and pointed MC at the mounted drive. MC plays it and displays the static screen images (which I'd rather not see).

I right-clicked, opened the DSP window and MC indicates that the source is two channel.
That contradicts DVD-AE, and I'm wondering if DVD-AE has got it wrong.

[syndromeofadown]

MC is playing the contents of the video_ts folder. (the standard dvd content)
DVDAE extracts the audio from the audio_ts folder. (the DVDAudio content)

If MC could play the DVDAudio content there would be no point in extracting it with another program.
mpl is the audio that exists in the audio_ts folder. You need to convert it to flac with DVDAE.

When you open the album with DVDAE it lists the contents of it in the left pane. Perhaps you should post a screen shot of this.

Thank you.
There are two selections in the left hand pane of DVDAE. I was selecting both. When I just selected the first one, I get the 6 channel audio. The second one is 2 channel and I guess that seemed to override the 6 channel extraction. Now, I've got my 6 channel rip

Thanks to everyone who replied; I greatly appreciate the input.

I need to understand the different formats, files, and structures of these different types of audio.

i have several BD audio and older DVD-A discs.   for DVD-A i just extract directly using DVDAE.   for bd audio, i use makemkv to decrypt and back up the disk.  then i open the backup in dvdae and select the appropriate title.  usually a PCM track as all my bd audio discs have three audio formats: PCM, Dolby TrueHD, DTS-MA.   dvdae nicely downloads metadata as. well.  well worth the money i spent for the license

if you dont have PCM or TrueHD and only dts-ma then you need to convert the dts audio.  there are ways to demux and convert.  i did it once but have long since forgotten the pipeline i used

i like to rip bluray concerts and extract the audio tracks to an album and import into jriver. this typically works great since most concerts have other thsn dts tracks, each song is a separate chapter, and dvdae handles them nicely

[mark_h]

For DTS-MA, just get DVD Audio Extractor to dump the raw DTS streams.  MC can play them and convert them to FLAC.

Sorry for being late to this thread. I've used DVDAE for many years but I've always avoided using it on DTS-MA. Fortunately, most of my discs also have PCM that I can extract, but can you explain what you mean by using DVDAE to "dump the raw DTS streams?"

[mark_h]

When you come to the extraction options, there's a choice to directly  save dts channels off to .dts files.  MC can play/convert these streams.

Direct Stream Demux

Excellent. I've heard and discussed the problem of using DVDAE on DTS-HD MA many times over the years but never heard of an easy solution until now. Many thanks.

[mojave]

For DVD-A discs, I use the free DVD-Audio Explorer 2008.

For Blu-ray, I use JRiver's Convert Format and select "convert video to audio". This extracts the 5.1 or 7.1 DTS-MA or Dolby TrueHD to multi-channel FLAC.

[BadMax]

I try to rip my first Audio DVD but surround and back channels are interchanged.

I tried DVD Audio Extractor and DVD-Audio Explorer.

In DVD-Audio Explorer i see: Lf-Rf-Ls-Rs
But only saving as mlp and looking at the properties in foobar says: FL FR FC LFE BL BR
