Hi There,

With the screen shots I meant of each step in DVD audio extractor. Just an idea on case anything stands out :)

I own the standalone dvd's of When In Rome; again no issue :/
 
I misspoke, my "When in Rome" DVDs are the standalone, I just store them with the Boxset. Here are the screenshots of the process, along with the Audacity of one of the FLAC files (for "Mama") running. The playback meter is pegged through much of this song, and is indicative of the rest of the DVD. Appreciate any assistance you guys can offer. Thanks.

Again, the weird thing being the DVDs play fine straight from the dic, but when I rip them the loudness and distortion become evident.

On the far left panel of the first screen; what chapter do you have selected?

It is Chapter 1 (Title 1). Since I only selected the one chapter (song) on the right it deselected "all" from the Title selection. When I ripped the entire disc the first time I just selected Title 1 and the DTS option below it.

I just ripped Mama to stereo instead of 6CH from the DTS (6Ch 48kHz) and the distortion and loudness are gone. But still there if I rip to 6ch. Something is definitely amiss here.
 
I’m not sure DVDAE still does this, but not long ago it would tell you, that you could only get 48Khz off a disc, but once you ripped it the 96Khz would be there. I know that’s not your issue, but these programs do have glitches and bugs.
Also try rebooting everything and don’t startup other programs when running the rip and see what happens.
 
Strictly Mac user here (until I switch to Linux). I used that Audiomuxer app for a brief period. It was a workaround for decoding dts2496 when the codec for a full decode was hard to find and everything was defaulting to core only. You could hack the codec into it. There was a codec available in a free demo that normally was only available in a $1200 software suite or something like that.

Audiomuxer was very kludgy! It was quickly retired with that codec when ffmpeg integrated it and decoding dts2496 became simple.

XLD and ffmpeg are the audio utilities I'd most recommend.

Rip those files to .dts (direct stream demux) with DVDAE and decode tham with ffmpeg. That should illuminate where the trouble is. (ie Baked into the .dts rip or downstream.) It's likely the dts handling codecs in DVDAE are old and not updated since forever. Like their core only dts2496 codec.
 
@jimfisheye I just ripped the first song (Mama) to .dts (Direct Stream Demux). Then used ffmpeg (ver 4.3.1) via "ffmpeg -i mama.dts mama.flac" command line. The resultant flac is still distorted in 6ch form. I have not used ffmpeg before, are there other options I should be using? I have not heard of XLD.

No other options required.

Looks like a MAC OS issue or latest DVDAE version which I have used yet. I’m still on previous version. The DVDAE change log mentions fixes for MACOS,...
 
I just ripped it again using the Windows version of DVDAE and still have the heavy distortion…only when ripped to 5.1, music is clean when ripped to stereo, regardless of Win or Mac.
 
You could try ripping to MKV using MakeMKV (free) then convert the MKV to FLAC using Audiomuxer or Music Media Helper (both Windows apps). That would eliminate DVDAE as the problem.
 
BTW: You could rip the concert to MKV which retains the DTS stream and use that to play back (skip conversion to audio only FLAC). Or rip to MKA (audio only version of MKV with DTS stream)
 
Thanks for the options Homer, but I am ripping this to play in my car which is setup to play 5.1 surround. MKV or MKA files are not playble files in this setup. FLAC is my only option for audio only playback.
 
G'day Hawkeye,

Well; now I can only, errr, amplify the mystery.

I cannot see any issue with what you've selected there in DVD AE. I do not run it on the highest priority but cannot see that being an issue given...

Attached is a screen shot of my Mama from my copy of the When in Rome DVD's; also done in 24 bit, 96 kHz. Fascinatingly, but perhaps not too surprisingly, it seems identical. Even the points at 100% seem identical!

Now I am relatively amateur compared to most responding on this thread BUT... I suspect something might be amiss with the playback. I am wondering if there is something funny on the playback side but also...

Comparing the stereo and 5.1 rips is interesting.
- the bass is relatively strong in the 5.1 mix; perhaps too strong;
- in stereo the drums are relatively strong in the mix;
- the vocals are far better isolated in the 5.1.

In other words, I think there might be an off chance that what you are hearing is "as designed" :-/

In case it is useful, below is my dynamic range report produce in foobar using the Dynamic Ranger Meter 1.1.1 plugin.

Nice track to pick for the comparison. This messed up track hooked me on Genesis in 2002---

Regards

Me

Hmmm... Not what I expected but really points to DVDAE. At least with that particular album. What is the dts format expected? dts2496? dts ma? core dts (24/48)?

Yeah, I'd try the DVD -> MKV -> ffmpeg route next.
And/or install an older version of DVDAE.
