I demuxed 2 BD's of The Aviator to use audio from import BD to Region A BD. German import has english DTS-HD Master Audio and I would like to use that with Region A BD with VC-1 because main track in it is AC3. Only problem is that the audio is not completely in synch.
I was thinking of converting DTS core and AC3 to wav with something like Wavelab and check the graph to see where the audio starts and add the delay when remuxing but that propably isn't the easiest way plus wavelab isn't freeware. Anyone have any ideas?

I don't quite understand why you you are bringing the Region A BD into the mix when your imported German disc has English DTS-HD Master Audio and a 1080p HD picture. Imported BD's, especially in AVC, are BETTER than VC-1 Region A BD's. Authoring/encoding houses in Germany actually know how to author/encode.

Only with flac, maybe you need:
eac3to.exe file.mkv 1: vid.mkv -slowdown 2: aud.flac -slowdown Quote:

I do believe The Aviator has the same master used for the Region A & B Discs. easiest way to compare is just open the file in vlc and take screenshots. another way is to index both .m2ts files with ffms2 and then do a stackhorizontal for side-by-side analysis of the same frame. But personally I would go with the AVC version with the higher bitrate.

Another question.
I'm trying to add AC3 track from Cars PAL DVD to Cars Region A BD. Everything goes fine except I think eac3to is remapping the channels incorrectly, I mean DVD ac3 should have the same channel order than in BD or am I wrong? Code:
D:\eac3to>eac3to e:\c.ac3 d:\cf.ac3 -slowdown AC3 EX, 5.1 channels, 1:51:44, 384kbps, 48kHz The Nero decoder doesn't seem to work, will use libav instead. Decoding with libav/ffmpeg... Remapping channels... Changing FPS from 25.000 to 23.976... Encoding AC3 <640kbps> with libAften... Creating file "d:\cf.ac3"... Clipping detected, a 2nd pass will be necessary. Starting 2nd pass... Decoding with libav/ffmpeg... Remapping channels... Changing FPS from 25.000 to 23.976... Encoding AC3 <640kbps> with libAften... Applying -0,28dB gain... Creating file "d:\cf.ac3"... eac3to processing took 25 minutes, 40 seconds. Done.

Remapping channels... is from ac3 internal order to uncompressed order, but the final ac3 have the same channel map than original.

http://forum.doom9.org/showthread.ph...81#post1212881 and also here (at the end of the post) is summary and conclusions from the tests: http://forum.doom9.org/showthread.ph...14#post1158014 in fact i tried recently even the latest Sonic version "4.3.0.238" and it can't work with eac3to at all.

http://forum.doom9.org/showthread.ph...85#post1443085 then it's obvious there is no match of the speaker positions between Mircosoft 5.1 WAV file and DTS-HD MA 5.1 - Microsoft 5.1 WAV files use only 0x3F as channel mask for 5.1 WAV files, which is FL, FR, FC, LFE, SL, SR. so, maybe i'm wrong somehow, but please explain. also, the same post gives information that DTS-HD MA 7.1 ("strange setup") tracks can be decoded with Sonic bit-perfectly to 5.1 channels that match DTS-HD MA 5.1 speaker positions, which is another thing that seems correct at least to me to be done. P.S. and the same question(s) for DTS-HD MA 7.1 not-"strange setup" tracks based on DTS and Microsoft channel layout diagrams and respectively speaker positions. [EDIT] BTW, in the mentioned old post, DTS channel layout diagrams are taken directly from DTS Labs software encoder software and Microsoft ones are from here: http://download.microsoft.com/downlo...krConfig5.docx page 6 and 7, where is also explained how Microsoft 5.1 WAV is played back on 7.1 channel system in Windows.

The angle between C-speaker and Rsr-speaker must be 150º, is not it? |

http://en.wikipedia.org/wiki/File:St..._placement.png The same for 5.1 config, the Surround channels can be located between 110º and 135º.

Of course MS WAV channels don't have a exact correlation with Surround channels, for that admit two ChannelMask for 5.1 config: 0x003F channel mask for FL, FR, FC, LF, BL, BR 0x060F channel mask for FL, FR, FC, LF, SL, SR Both must be played in the exact way: - A 5.1 system must consider the last channels as Surround channels (120º more o less). - A 7.1 system must split the Surround channels between Side and Back channels. Quote:
For me the standard 7.1 have a exact correlation with MS channels (and standard location of speakers in a 7.1 audio system), but we need make some correction for "strange setup" Also a receiver than accept 7.1 but have only 5.1 speakers must do some correction not only ignore the channels.

sorry, but i'm confused and i believe i'm not the only one having the same questions regarding this subject.
Quote:
http://download.microsoft.com/downlo...krConfig5.docx on page 9 Microsoft make it very clear that 5.1 WAV files no matter of the actual channel mask in newer versions of Windows are treatеd as with channel mask of 0x3F and effectively there is no channel mask of 0x060F, because even that channel mask is actually used it's the same for Windows as channel mask of 0x3F and thus in practice there is only one channel mask for 5.1 WAV files: Quote:
Quote:
so, do you say that SL and SR in Microsoft world is what in DTS world is "Ls" ans "Rs"? because that is in contradiction with DTS 5.1 speaker positions: http://www.imagebam.com/image/addcf997797266 and Microsoft 5.1 speaker positions as defined in page 6 "Playing a 5.1-Channel Stream on a 7.1 Speaker Configuration" of "SpkrConfig5.docx" document. that's the most confusing part at least for me.

DTS-HD MA 7.1 (normal setup): http://www.imagebam.com/image/43bb3497794528 and Microsoft 7.1 setup: http://www.imagebam.com/image/160e7497795034 considering how DTS-HD MA 5.1 speaker position is: http://www.imagebam.com/image/addcf997797266 and that there is no match in speaker position of Microsoft and DTS for 5.1 channels setup at least from what's defined in "SpkrConfig5.docx" document. anyway, i don't want to argue about it, but there is no doubt it's very confusing.

Code:
// Speaker Positions: #define SPEAKER_FRONT_LEFT 0x1 #define SPEAKER_FRONT_RIGHT 0x2 #define SPEAKER_FRONT_CENTER 0x4 #define SPEAKER_LOW_FREQUENCY 0x8 #define SPEAKER_BACK_LEFT 0x10 #define SPEAKER_BACK_RIGHT 0x20 #define SPEAKER_FRONT_LEFT_OF_CENTER 0x40 #define SPEAKER_FRONT_RIGHT_OF_CENTER 0x80 #define SPEAKER_BACK_CENTER 0x100 #define SPEAKER_SIDE_LEFT 0x200 #define SPEAKER_SIDE_RIGHT 0x400 ... #define KSAUDIO_SPEAKER_5POINT1 (SPEAKER_FRONT_LEFT | SPEAKER_FRONT_RIGHT | \ SPEAKER_FRONT_CENTER | SPEAKER_LOW_FREQUENCY | \ SPEAKER_BACK_LEFT | SPEAKER_BACK_RIGHT) ... #define KSAUDIO_SPEAKER_5POINT1_SURROUND (SPEAKER_FRONT_LEFT | SPEAKER_FRONT_RIGHT | \ SPEAKER_FRONT_CENTER | SPEAKER_LOW_FREQUENCY | \ SPEAKER_SIDE_LEFT | SPEAKER_SIDE_RIGHT) KSAUDIO_SPEAKER_5POINT1 = 0x3F with BL, BR KSAUDIO_SPEAKER_5POINT1_SURROUND = 0x60F with SL, SR but both must be played the same. Other question is how the system mixer work: - If the input is a 5.1 0x60F the output is 5.1 0x3F, no problem. - If the input is 7.1 and need 5.1 output, discards channels 4 and 5 (BL,BR) and send a 5.1 0x3F with original channels SL, SR. This undesired behaviour can be modified using filters like ffdshow. But all of this is irrelevant to your question: Quote:
Forget also all the figures about exact speakers position in the MS docx, the audio is created like DTS (or DD) say and real audio systems must have the speakers located like DTS-DD say: - For a 5.1 system: Surround channels at 110º-120º (not Side 90º nor Back 150º) - For a 7.1 system: Side channels at ~90º, Back channels ~150º

- I encode the 8 channels to 7.1 "strange setup" and after decoded with ArcSoft. - The max peak of each channel in decoded wav say me the coefficients
