With 7.1 config the order in wav files is: FL FR FC LF BL BR SL SR
and mean:
BL BR = Back Channels at 150║ (more or less)
SL SR = Side Channels at 90║ (more or less)

Like you can see don't exist (in wav specs) a exact correspondence with Surround channels in 5.1 (120║)
Before XP SP2 the FL FR FC LF BL BR maskchannels was used for 5.1, after the FL FR FC LF SL SR was recommended but the previous one is also accepted.
I figured that the difference between Back and Side channels were their angle compared to the Center, and that the difference does matter in 7.1 far more than it does in 5.1.

I took that Dolby/DTS snippet from one of Microsoft's pages detailing Channel Masks (albeit in the case of WMA 9 Pro):

"The 5.1 and 7.1 Dolby configurations make use of SL and SR speakers, while the 5.1 DTS system, the default used by Windows Media, places the side speakers in the back (BL and BR). The 7.1 SDDS configuration, which is the default used in Microsoft Windows« XP, makes use of five front speakers. Although this configuration is used commonly in large commercial theaters, it may not provide the best experience in a home system."

I never see this:
5.1 (DTS) FL, FR, C, LFE, BL, BR (63)
5.1 (Dolby) FL, FR, C, LFE, SL, SR (1551)

Of course is a big absurdity, the users don't need move the surround speakers to 90║ whe listen AC3 and to 140║ when listen DTS.

the latest 1.1.0.10 doesn't work with eac3to though. anyway, it's interesting if they fixed the problem with DTS-HD MA tracks reported by eac3to as "7.1 (strange setup)". as you know such tracks are not bit-perfect decoded by old 1.1.0.0 versions of "dtsdecoderdll.dll"
Ugh! So what is the version of choice we should all use?
I just confirmed I'm still on 1.1.0.0 - will I need to update? Can I replace just this dll (I don't really want to update the whole TMT software suite, because they keep on getting worse as the build numbers progress).

@madshi,
When you have time and get back to eac3to, would you be kind enough to add a switch to be able to turn off the audio alerts please? I was watching one of my shows with eac3to running some operations in the background and it was really annoying to hear the alerts over the program. Thank you.

If you delete the success and error wavs then this will silence eac3to.

EDIT - Atak_Snajpera beat me to it!

eac3to is reporting 189 chapters when there's only 16 reported by BdInfo.

What kind of information should I send to madshi?

Can "eac3to" be used to "timestretch" (or shorten) an .AC3 audiostream of a BluRay?

If so, how?

Hi!

Thanks for the suggestion(s), but based on their definitions ("-slowdown convert 25.000 and 24.000 content to 23.976 fps"
"-speedup convert 23.976 and 24.000 content to 25.000 fps") they appear to be specifically for NTSC to PAL and PAL to NTSC conversion. (If my interpretation is incorrect, please advise)

What I'm seeking at the moment is to evenly, over the duration of the audiostream, shorten the audiostream by 700ms...

See the 2nd link, in the quote, below. If your's is dated 4/25/08 vs 4/21/08, then you're OK. If not, then you should update to the dll ver 1.1.0.1

Was solved with a more recent version of dtsdecoderdll.dll <-----

Hey guys, I'm looking for a simple program that will display volume levels of an audio track (DTS, AC-3) graphically, I suppose.
There's a VU meter built into either VLC or MPC, but it's indicators hardly move so there's no easy way to compare tracks. I've done a search and can't find anything. Thanks

Thank you all. Believe it or not, I actually thought of that after I posted the message. It would still be a useful switch though. I find the audiible warnings useful except under certain circumstances. It would be easier to not have to delete or rename them just for those cases.

AC3Filter and/or MatrixMixer should be able to do the trick.

But if you prefer the stupid nerdish methods ,
you could as well "AudioDub" a BlankClip and apply
Histogram("AudioLevels") onto it.

Thanks madshi for contacting me directly about this file. It does use spectral extension. I had implemented the feature in the "sandbox" repository from the original Google Summer of Code project, but had not merged to FFmpeg SVN because I only had 1 sample file to test... until now!! With this sample and another (also provided by madshi) working properly, I decided to merge the changes to FFmpeg SVN.
@jruggle:
Do you remember my problem?
Do you have some informations how do convert the file into another format like .wav?
I tried it with ffmpeg 0.5, but i failed.

thank you very much...

how can I transform a .thd track to .dts again? when I enter it that way 'eac3to source.thd dest.dts' then I get 6 wav files first, but which are apparently not accepted by the surcode dts encoder and the process is cancelled.

How can I disable "Patching bitdepth to 24 bits..." during extracting Core from DTS-HD?

Thanks for the tool.

It's good to know that it's finally possible to convert TrueHD.
As I've been playing around with Nero these past days, could you tell what sort of working graph permit the decoding of TrueHD ?
Is it Nero Splitter -> Nero Audio Decoder 2 ?
Do you need to specify anything in the Nero Audio Decoder 2 options ?
